00:11:12,839 He decided he couldn't raise a child in that environment, 204 00:11:12,881 --> 00:11:16,718 and decided that it was time to leave. 205 00:11:17,344 --> 00:11:20,263 He had taken a couple of parental classes, 206 00:11:20,305 --> 00:11:23,183 and he was looking into buying a crib. 207 00:11:23,224 --> 00:11:25,727 He thought after the baby was born, 208 00:11:25,769 --> 00:11:28,396 they'd find some even ground. 209 00:11:28,438 --> 00:11:32,859 [music] 210 00:11:32,901 --> 00:11:34,944 [Narrator] But just months later, 211 00:11:34,986 --> 00:11:37,781 this new father is found dead from a gunshot 212 00:11:37,822 --> 00:11:40,033 in his own garage. 213 00:11:41,242 --> 00:11:44,204 Authorities begin a sweep of the crime scene, 214 00:11:44,245 --> 00:11:48,416 while investigators track down Michael's family and ex, 215 00:11:48,625 --> 00:11:50,251 Kathryn Sinkevitch. 216 00:11:51,378 --> 00:11:54,047 [Shawn] They obtained an emergency cell phone ping 217 00:11:54,089 --> 00:11:57,550 to figure out where Miss Sinkevitch was located. 218 00:11:58,009 --> 00:11:59,135 There was no murder weapon, 219 00:11:59,177 --> 00:12:00,887 there was no gun found at the scene. 220 00:12:00,929 --> 00:12:02,389 The investigator could see 221 00:12:02,430 --> 00:12:05,141 the wound to the left side of his temple was obvious. 222 00:12:08,228 --> 00:12:12,732 [Narrator] But there's evidence that wasn't the only shot fired. 223 00:12:12,774 --> 00:12:15,402 They noticed that there was three casings, 224 00:12:15,443 --> 00:12:18,113 on the, on the garage floor. 225 00:12:18,571 --> 00:12:20,490 [Narrator] Detectives take a closer look 226 00:12:20,532 --> 00:12:23,410 to find where the other two shots landed. 227 00:12:23,451 --> 00:12:28,289 They find that Michael was hit not once, but twice. 228 00:12:28,957 --> 00:12:31,251 It turns out that he was also shot once in the back. 229 00:12:31,292 --> 00:12:33,545 The third shot apparently missed Michael. 230 00:12:34,337 --> 00:12:37,549 This was a shocking event to a fairly peaceful suburb. 231 00:12:37,590 --> 00:12:39,968 So, to have something like this, to have someone, you know, 232 00:12:40,010 --> 00:12:41,386 shot and killed inside the garage, 233 00:12:41,428 --> 00:12:44,139 it was highly unusual and startling for everyone. 234 00:12:44,180 --> 00:12:46,975 [music] 235 00:12:47,017 --> 00:12:48,435 [Narrator] Coming up... 236 00:12:48,476 --> 00:12:51,855 The investigation uncovers shocking footage. 237 00:12:52,188 --> 00:12:54,941 There's a figure dressed all in black 238 00:12:54,983 --> 00:12:57,652 that runs very quickly up the driveway. 239 00:12:57,986 --> 00:13:00,739 [Narrator] And authorities learn the details of 240 00:13:00,780 --> 00:13:02,615 a harrowing phone call. 241 00:13:02,949 --> 00:13:04,617 [Marlie] I was talkin' to Mike. 242 00:13:04,659 --> 00:13:06,619 I had heard three booms. 243 00:13:06,661 --> 00:13:09,080 I knew there was something wrong. 244 00:13:23,219 --> 00:13:26,598 [Narrator] On December 16th, 2016, 245 00:13:26,639 --> 00:13:30,435 authorities in Maricopa, Arizona discover the body 246 00:13:30,477 --> 00:13:34,564 of 31-year-old Michael Agerter in his garage. 247 00:13:35,148 --> 00:13:36,858 [Michael] Three bullets were fired. 248 00:13:36,900 --> 00:13:39,402 One of the bullets struck the B-pillar. 249 00:13:39,444 --> 00:13:42,322 Two of the other three that were fired struck Michael. 250 00:13:42,364 --> 00:13:43,948 One in the left side of the head, 251 00:13:43,990 --> 00:13:46,034 and then one that had gone through 252 00:13:46,076 --> 00:13:49,037 a lower part of the door and seat, 253 00:13:49,079 --> 00:13:51,915 and was wedged in the body in the back. 254 00:13:53,583 --> 00:13:57,754 Once they had the scene somewhat contained, 255 00:13:57,796 --> 00:14:00,173 they did a safety sweep of the house. 256 00:14:07,263 --> 00:14:09,849 They made sure there was no other victims inside the house, 257 00:14:09,891 --> 00:14:11,601 or anyone who was hiding in the house. 258 00:14:12,602 --> 00:14:15,188 [Shawn] It didn't appear that there was anything missing. 259 00:14:15,230 --> 00:14:17,982 Nothing inside the house looked like it had been ransacked, 260 00:14:18,024 --> 00:14:19,776 like there was an attempted robbery. 261 00:14:20,318 --> 00:14:22,946 [Narrator] But officers do find something inside 262 00:14:22,987 --> 00:14:24,572 that gets their attention. 263 00:14:27,575 --> 00:14:29,869 They noticed there was a home surveillance system 264 00:14:29,911 --> 00:14:31,246 in Michael's house. 265 00:14:31,287 --> 00:14:35,083 [music] 266 00:14:35,125 --> 00:14:37,002 [Narrator] In order to view the footage, 267 00:14:37,043 --> 00:14:40,130 investigators will need permission from a judge. 268 00:14:41,256 --> 00:14:43,008 While waiting on the warrant, 269 00:14:43,049 --> 00:14:45,260 investigators talk with Michael's neighbors, 270 00:14:45,301 --> 00:14:47,262 who have gathered outside. 271 00:14:54,728 --> 00:14:57,105 [Narrator] Most report that they don't know Michael, 272 00:14:57,147 --> 00:14:59,232 who only recently moved in. 273 00:15:01,109 --> 00:15:03,403 However, several do report 274 00:15:03,445 --> 00:15:05,989 seeing a vehicle parked in front of his house 275 00:15:06,031 --> 00:15:08,742 moments before the shots rang out. 276 00:15:14,664 --> 00:15:17,292 [Narrator] But the accounts of who was driving the van 277 00:15:17,334 --> 00:15:19,753 are inconsistent at best. 278 00:15:20,337 --> 00:15:22,630 We had quite a few different descriptors 279 00:15:22,672 --> 00:15:24,132 of the driver. 280 00:15:24,174 --> 00:15:26,760 We had a Black male, we had a Black female, 281 00:15:26,801 --> 00:15:30,305 we had a Hispanic female, we had a white female. 282 00:15:30,347 --> 00:15:34,768 [music] 283 00:15:34,809 --> 00:15:38,646 [Narrator] With minimal details on the driver from neighbors, 284 00:15:38,688 --> 00:15:40,315 investigators switch gears 285 00:15:40,357 --> 00:15:44,027 and take a look at the footage from Michael's security cameras. 286 00:15:45,987 --> 00:15:48,365 [Michael] You could see a white minivan 287 00:15:49,032 --> 00:15:52,702 parked across the street, just to the west. 288 00:15:53,244 --> 00:15:56,039 The van waited across the street for a number of minutes. 289 00:15:56,456 --> 00:16:00,502 Then you see a subject get out of the car, 290 00:16:00,543 --> 00:16:02,045 wearing a hoodie. 291 00:16:02,087 --> 00:16:05,632 [music] 292 00:16:05,674 --> 00:16:09,177 They see footage of Michael's Lexus pulling into the garage. 293 00:16:10,178 --> 00:16:13,098 There's a figure dressed all in black 294 00:16:13,139 --> 00:16:15,892 that runs very quickly up the driveway. 295 00:16:15,934 --> 00:16:19,688 [music] 296 00:16:19,729 --> 00:16:22,357 [gunshots] 297 00:16:22,399 --> 00:16:26,361 [music] 298 00:16:26,403 --> 00:16:28,863 [Michael] And then approximately 11 seconds later, 299 00:16:28,905 --> 00:16:31,116 this subject is seen running away. 300 00:16:31,616 --> 00:16:35,495 In that 11 seconds, Michael was executed. 301 00:16:35,537 --> 00:16:38,373 [music] 302 00:16:38,415 --> 00:16:41,376 [Narrator] Between the hoodie and the angle of the cameras, 303 00:16:41,418 --> 00:16:45,213 investigators can't get a look at the person's face. 304 00:16:46,423 --> 00:16:49,509 Authorities are still talking to potential witnesses 305 00:16:49,551 --> 00:16:53,555 when they finally get in touch with Michael's family in Ohio. 306 00:16:54,389 --> 00:16:57,559 His sister Marlie reveals horrifying details 307 00:16:57,600 --> 00:17:00,603 about her last conversation with Mike. 308 00:17:01,438 --> 00:17:02,939 [Marlie] I was talkin' to Mike 309 00:17:02,981 --> 00:17:04,858 through the Bluetooth in his car. 310 00:17:04,899 --> 00:17:06,651 He had asked me to hold on, 311 00:17:06,693 --> 00:17:10,238 to switch over to the phone instead of the car. 312 00:17:11,406 --> 00:17:14,200 And the next thing was... 313 00:17:14,993 --> 00:17:17,328 He had said, "Holy [bleep]." 314 00:17:19,372 --> 00:17:22,459 And I had heard three gunshots. 315 00:17:23,918 --> 00:17:26,379 And then I didn't hear anything. 316 00:17:29,424 --> 00:17:32,802 I knew there was something wrong. 317 00:17:34,637 --> 00:17:38,933 [Narrator] Marlie tried calling Michael again, to no avail. 318 00:17:38,975 --> 00:17:41,311 [Marlie] It was very hard for me, 319 00:17:41,770 --> 00:17:43,855 because I'm all the way here in Ohio. 320 00:17:44,356 --> 00:17:46,775 And, and I, I had no way to help him. 321 00:17:47,859 --> 00:17:52,447 So I had called my parents, and my dad answered. 322 00:17:52,489 --> 00:17:56,868 And at the time, I told him that I had heard three booms. 323 00:17:57,660 --> 00:18:01,289 I was worried that if I told him that I had heard gunshots, 324 00:18:01,331 --> 00:18:03,083 he would think I was being dramatic. 325 00:18:03,667 --> 00:18:08,463 So, we had called Chris Grindey to go make sure that he's okay. 326 00:18:09,339 --> 00:18:11,841 Later we found out that the police were 327 00:18:12,509 --> 00:18:16,721 at his house within minutes of when I heard gunshots. 328 00:18:17,931 --> 00:18:20,642 The detectives couldn't tell us anything over the phone. 329 00:18:20,684 --> 00:18:23,478 So we hopped in the car, went to my mom's house. 330 00:18:24,813 --> 00:18:29,150 And my mom said that they were sending a sheriff to our house. 331 00:18:29,192 --> 00:18:33,571 And so I knew at that point that he was gone. 332 00:18:36,700 --> 00:18:39,577 [Narrator] Meanwhile, detectives switch their focus 333 00:18:39,619 --> 00:18:42,747 back to locating Michael's ex, Kathryn, 334 00:18:42,789 --> 00:18:46,042 and look up the make and model of her vehicle. 335 00:18:46,793 --> 00:18:49,421 They discover that it's not a white minivan. 336 00:18:49,462 --> 00:18:51,131 They discover it's a blue car 337 00:18:51,172 --> 00:18:54,175 that doesn't even come close to meeting that description. 338 00:18:54,676 --> 00:18:58,179 [Narrator] Even so, investigators are still eager 339 00:18:58,221 --> 00:18:59,723 to speak with her. 340 00:19:02,892 --> 00:19:07,605 That same day, authorities track Kathryn to a home in Mesa, 341 00:19:07,647 --> 00:19:11,067 just a 40-minute drive from where Michael was shot. 342 00:19:11,568 --> 00:19:14,362 [Michael] When the initial officers arrived, 343 00:19:14,404 --> 00:19:16,197 they observed Kathryn's vehicle, 344 00:19:16,239 --> 00:19:18,491 and they observed a white minivan. 345 00:19:19,492 --> 00:19:21,703 [Kent] Lo and behold, right beside her vehicle 346 00:19:21,745 --> 00:19:26,249 is a white van that meets the exact description of the van 347 00:19:26,291 --> 00:19:28,335 that was used by the killer. 348 00:19:29,669 --> 00:19:33,089 [Michael] So we ran that license plate, 349 00:19:33,590 --> 00:19:36,343 and that came back to the registered owner as 350 00:19:36,384 --> 00:19:40,263 a Bridget Hopkins in Mesa. 351 00:19:41,973 --> 00:19:44,434 When we are making contact with Kathryn Sinkevitch 352 00:19:44,476 --> 00:19:48,355 at Bridget Hopkins' house, it was a pretty tense situation. 353 00:19:48,980 --> 00:19:50,357 [Narrator] Detectives request 354 00:19:50,398 --> 00:19:53,401 that everyone in the house come outside. 355 00:19:53,443 --> 00:19:56,029 Officers have to pull everyone out for safety reasons, 356 00:19:56,071 --> 00:20:00,241 including Bridget, her husband, their children, 357 00:20:00,617 --> 00:20:03,578 as well as Kathryn and her newborn. 358 00:20:04,621 --> 00:20:06,831 [Narrator] When detectives inform Kathryn 359 00:20:06,873 --> 00:20:08,416 of Michael's murder, 360 00:20:08,458 --> 00:20:11,628 her reaction takes them by surprise. 361 00:20:12,379 --> 00:20:15,215 One thing that struck me, she was very stoic. 362 00:20:15,256 --> 00:20:18,677 We asked if she and Bridget would be willing to come down 363 00:20:18,718 --> 00:20:20,845 and speak to us at the city of Maricopa, 364 00:20:20,887 --> 00:20:23,473 our police department, and they consented. 365 00:20:23,515 --> 00:20:25,850 Kathryn said absolutely. 366 00:20:28,728 --> 00:20:31,606 [Narrator] When asked about her whereabouts earlier, 367 00:20:31,648 --> 00:20:33,900 Kathryn tells investigators that she was at 368 00:20:33,942 --> 00:20:38,196 the mortgage company where she and Bridget both work all day. 369 00:20:38,947 --> 00:20:41,950 Kathryn said that she got up, got ready to go to work, 370 00:20:41,991 --> 00:20:44,786 dropped her baby off at the babysitter's house, 371 00:20:44,828 --> 00:20:47,539 got to work right around eight o'clock, 372 00:20:47,580 --> 00:20:49,457 was there all day. 373 00:20:49,499 --> 00:20:51,626 "I left at 5, picked my child up." 374 00:20:51,668 --> 00:20:54,713 And then goes over to Bridget's house. 375 00:20:55,964 --> 00:20:58,508 [Kent] Law enforcement continued to ask additional questions, 376 00:20:59,009 --> 00:21:01,469 tried to get more details, and she invokes and says, 377 00:21:01,511 --> 00:21:03,304 "I'm not answering any further questions 378 00:21:03,346 --> 00:21:05,015 without an attorney present." 379 00:21:08,810 --> 00:21:11,604 [Narrator] Investigators move on to Bridget, 380 00:21:11,646 --> 00:21:14,149 who explains that she is Kathryn's coworker 381 00:21:14,190 --> 00:21:15,650 at the mortgage company, 382 00:21:15,692 --> 00:21:18,069 and they have known each other for about a year. 383 00:21:18,445 --> 00:21:21,072 Bridget corroborates Kathryn's alibi. 384 00:21:21,114 --> 00:21:24,909 We explained that there had been a homicide with Michael Agerter, 385 00:21:24,951 --> 00:21:28,204 who had been in a relationship with Kathryn. 386 00:21:28,246 --> 00:21:32,709 So, we were trying to establish all the different nexuses. 387 00:21:33,168 --> 00:21:34,794 She was very shocked to think 388 00:21:34,836 --> 00:21:38,381 that we would even consider Kathryn as the... 389 00:21:38,423 --> 00:21:41,760 suspect in

what her day was like, she said that 393 00:21:49,142 --> 00:21:50,435 she went to work, 394 00:21:50,477 --> 00:21:52,103 got to work around eight o'clock... 395 00:21:52,145 --> 00:21:56,524 She left to go get a lunch, she came back, ate her lunch, 396 00:21:56,566 --> 00:21:57,692 and then went back to her desk 397 00:21:57,734 --> 00:21:59,361 and worked there until she got off of work 398 00:21:59,402 --> 00:22:00,737 at approximately five o'clock. 399 00:22:02,322 --> 00:22:04,074 [Narrator] Even though they have no proof Bridget's van 400 00:22:04,115 --> 00:22:06,034 is the one in the surveillance footage, 401 00:22:06,076 --> 00:22:09,371 investigators aren't taking any chances. 402 00:22:09,829 --> 00:22:12,374 The police had reason to suspect 403 00:22:12,415 --> 00:22:13,708 that that vehicle might've been involved. 404 00:22:13,750 --> 00:22:15,669 So they seize Bridget's van. 405 00:22:17,837 --> 00:22:21,925 [Narrator] But they can't hold on to Bridget or Kathryn. 406 00:22:22,842 --> 00:22:24,386 [Kent] So after getting nowhere with 407 00:22:24,427 --> 00:22:26,388 their initial interview with Kathryn, 408 00:22:26,429 --> 00:22:27,972 but still believing that, 409 00:22:28,014 --> 00:22:30,183 that something wasn't quite right, 410 00:22:30,225 --> 00:22:31,810 they went back to the family. 411 00:22:33,269 --> 00:22:34,270 And what they discovered 412 00:22:35,772 --> 00:22:38,733 really started to concern Maricopa PD and the detectives. 413 00:22:38,775 --> 00:22:41,361 [music] 414 00:22:41,403 --> 00:22:42,696 [Narrator] Coming

took off with him. 418 00:22:50,328 --> 00:22:52,372 And it was devastating when it happened. 419 00:22:52,914 --> 00:22:56,584 He got permission from the owner of the house 420 00:22:56,626 --> 00:23:01,506 to install video cameras so that he would have proof. 421 00:23:16,312 --> 00:23:19,024 [Narrator] Investigators in Maricopa, Arizona 422 00:23:19,065 --> 00:23:22,318 are looking into the execution-style murder 423 00:23:22,360 --> 00:23:25,238 of 31-year-old Michael Agerter. 424 00:23:26,740 --> 00:23:30,118 While Michael's ex, Kathryn, is unwilling to talk about 425 00:23:30,160 --> 00:23:32,537 their relationship with investigators, 426 00:23:32,996 --> 00:23:36,875 they find that his loved ones have plenty to say. 427 00:23:37,834 --> 00:23:40,003 [Marlie] When Mike and Kathryn first got together, 428 00:23:40,045 --> 00:23:42,172 he said that they could have fun together. 429 00:23:42,213 --> 00:23:43,757 Mike was highly intelligent, 430 00:23:43,798 --> 00:23:46,092 and Kathryn's pretty intelligent too, 431 00:23:46,134 --> 00:23:49,054 so they could have conversations on that same level. 432 00:23:50,096 --> 00:23:51,556 When I first met her, 433 00:23:51,598 --> 00:23:55,060 she really was a very nice, kind person. 434 00:23:58,229 --> 00:24:01,524 [Narrator] But just months into her relationship with Michael, 435 00:24:01,566 --> 00:24:05,236 Kathryn's behavior took a sharp turn. 436 00:24:05,779 --> 00:24:09,366 [Mark] She would just go off and break dishes, 437 00:24:09,991 --> 00:24:13,578 do crazy things, throw things around. 438 00:24:14,579 --> 00:24:16,456 [Marlie] Kathryn was a very jealous person. 439 00:24:16,498 --> 00:24:20,794 Once she accused him of cheating on her 440 00:24:20,835 --> 00:24:23,213 with me, his sister. 441 00:24:23,963 --> 00:24:28,760 And then I think she realized how ridiculous that sounded, 442 00:24:29,219 --> 00:24:30,595 and... 443 00:24:30,637 --> 00:24:33,223 then the accusation turned into 444 00:24:33,264 --> 00:24:36,976 I helped him cheat on her. 445 00:24:40,105 --> 00:24:42,482 [Narrator] Michael's friend and former roommate, 446 00:24:42,524 --> 00:24:44,693 Chris Grindey, had a front row seat 447 00:24:44,734 --> 00:24:47,737 to Kathryn's erratic behavior. 448 00:24:47,779 --> 00:24:50,699 I saw that she really wasn't this nice person, 449 00:24:51,032 --> 00:24:52,784 that she really was a controlling person. 450 00:24:52,826 --> 00:24:55,745 And she started to control his actions 451 00:24:55,787 --> 00:24:57,747 when I wanted to do something with him. 452 00:24:57,789 --> 00:24:59,916 She was a very passive-aggressive person. 453 00:24:59,958 --> 00:25:02,627 She would just make, you know, snide comments. 454 00:25:03,378 --> 00:25:05,296 At that, that point I said, "I'm, I'm done. 455 00:25:05,338 --> 00:25:06,589 I'm not gonna live with her," 456 00:25:06,631 --> 00:25:09,050 and I put in my notice to the landlord. 457 00:25:09,092 --> 00:25:13,179 [music] 458 00:25:13,221 --> 00:25:15,765 [Narrator] Friends and family say Mike held on 459 00:25:15,807 --> 00:25:19,269 even as things started to deteriorate. 460 00:25:19,310 --> 00:25:22,272 He always was generous about everything, so in his mind, 461 00:25:22,313 --> 00:25:23,773 he wants to be the savior. 462 00:25:23,815 --> 00:25:25,316 Financially, she was struggling. 463 00:25:25,358 --> 00:25:28,653 He stayed because he truly felt like he wanted to, 464 00:25:28,695 --> 00:25:31,406 to help her in her situation, no matter what. 465 00:25:32,157 --> 00:25:34,993 [Narrator] Michael's loved ones say that the verbal abuse 466 00:25:35,035 --> 00:25:37,829 eventually turned physical. 467 00:25:38,329 --> 00:25:40,999 She had knocked him out... 468 00:25:41,041 --> 00:25:43,209 two or three different times. 469 00:25:43,251 --> 00:25:45,045 She had headbutted him. 470 00:25:46,004 --> 00:25:48,131 [Leslie] He'd tell me that they had a fight, 471 00:25:48,173 --> 00:25:50,800 and he didn't know if he wanted to stay in the relationship. 472 00:25:50,842 --> 00:25:53,053 And I'm like, "You don't stay like that, 473 00:25:53,094 --> 00:25:55,930 subject yourself to that kind of abuse." 474 00:25:58,850 --> 00:26:01,269 [Narrator] In March of 2016, 475 00:26:01,311 --> 00:26:04,147 their relationship was hanging on by a thread 476 00:26:04,189 --> 00:26:07,525 when Kathryn revealed that she was pregnant. 477 00:26:08,026 --> 00:26:11,196 I remember saying, "I hope you're not gonna marry her." 478 00:26:11,780 --> 00:26:13,948 He's like, "Yeah, no, that won't happen, 479 00:26:13,990 --> 00:26:16,785 but I definitely want to support my child." 480 00:26:19,954 --> 00:26:22,290 [Narrator] Friends and family say that not long after 481 00:26:22,332 --> 00:26:24,959 getting the news of Kathryn's pregnancy, 482 00:26:25,001 --> 00:26:27,962 Michael was finally ready to break it off. 483 00:26:28,755 --> 00:26:32,884 Four months after moving out, Chris got a call from Michael. 484 00:26:33,259 --> 00:26:36,221 He tells me that, "She just bit me." 485 00:26:37,472 --> 00:26:39,057 "I had to get stitches." 486 00:26:39,599 --> 00:26:41,226 And I'm like, "Wow," and he's like, 487 00:26:41,267 --> 00:26:43,520 "I, I got to leave her. Can you help me?" 488 00:26:43,561 --> 00:26:44,979 And I'm like, "Sure." 489 00:26:45,021 --> 00:26:47,023 He said, "This relationship can't go on. 490 00:26:47,065 --> 00:26:49,192 This craziness can't go on." 491 00:26:50,610 --> 00:26:53,947 [Narrator] Around eight months before he was found dead, 492 00:26:53,988 --> 00:26:56,032 Michael took the dog, Darwin, 493 00:26:56,074 --> 00:26:59,119 and moved into a home in Maricopa. 494 00:26:59,577 --> 00:27:01,830 Kathryn was furious. 495 00:27:03,915 --> 00:27:05,875 [Chris] She hired a private investigator, 496 00:27:05,917 --> 00:27:07,711 found where he lived. 497 00:27:07,752 --> 00:27:10,338 She had to pick a time when he was gone. 498 00:27:10,380 --> 00:27:13,717 The dog door was open, so all she had to do was call him. 499 00:27:13,758 --> 00:27:16,261 She grabbed Darwin and took off with him. 500 00:27:17,345 --> 00:27:19,931 And it was devastating when it happened. 501 00:27:21,182 --> 00:27:23,351 [Narrator] Investigators learn that Michael had tried 502 00:27:23,393 --> 00:27:27,105 to take legal action of his own against Kathryn. 503 00:27:27,605 --> 00:27:30,066 They discover that there was an order of protection 504 00:27:30,108 --> 00:27:33,069 that Michael had filed in April of 2016 505 00:27:33,111 --> 00:27:35,572 against his ex-girlfriend, Kathryn. 506 00:27:36,448 --> 00:27:40,368 He got permission from the owner of the house 507 00:27:40,410 --> 00:27:42,829 to install video cameras, 508 00:27:42,871 --> 00:27:46,624 so that if any other incidents would happen, 509 00:27:46,666 --> 00:27:48,543 that he would have proof. 510 00:27:48,585 --> 00:27:52,839 [music] 511 00:27:52,881 --> 00:27:56,468 [Narrator] However, Kathryn refused to let up. 512 00:27:57,177 --> 00:28:01,139 Following the birth of their son in October 2016, 513 00:28:01,514 --> 00:28:05,560 she launched a vicious and hurtful campaign. 514 00:28:06,311 --> 00:28:10,899 He was just in the process of starting to get visitations, 515 00:28:10,940 --> 00:28:15,528 and, you know, establish his parental rights. 516 00:28:16,571 --> 00:28:19,157 In court, she announced that, 517 00:28:19,491 --> 00:28:22,952 well, Mike wasn't the father of the baby. 518 00:28:24,162 --> 00:28:28,375 I never believed that, and he, he never believed that. 519 00:28:29,167 --> 00:28:31,127 The family court judge determined 520 00:28:31,169 --> 00:28:33,171 that there would be DNA testing. 521 00:28:33,797 --> 00:28:35,465 [Narrator] In fact, Marlie says 522 00:28:35,507 --> 00:28:37,634 when she was on the phone with Michael 523 00:28:37,676 --> 00:28:39,052 at the time of the murder, 524 00:28:39,094 --> 00:28:41,846 he was returning home from taking the test. 525 00:28:42,514 --> 00:28:45,892 He was going to prove that his son was his son, 526 00:28:45,934 --> 00:28:49,145 so that hopefully he could see him soon. 527 00:28:49,187 --> 00:28:52,565 [music] 528 00:28:52,607 --> 00:28:55,527 [Narrator] In light of the new information about Kathryn, 529 00:28:55,568 --> 00:28:58,154 investigators head to the mortgage company 530 00:28:58,196 --> 00:29:00,782 where she works with her friend Bridget. 531 00:29:00,824 --> 00:29:03,118 They check in with building security 532 00:29:03,159 --> 00:29:05,036 and ask to see surveillance footage 533 00:29:05,078 --> 00:29:09,332 from the day of the murder, and they spot a white van. 534 00:29:09,833 --> 00:29:13,628 [Michael] We're looking at the security video of the building. 535 00:29:13,670 --> 00:29:18,341 We see the white minivan pulling into the parking lot. 536 00:29:18,758 --> 00:29:22,470 [Narrator] But a few hours later, the van leaves. 537 00:29:23,054 --> 00:29:25,265 They see Bridget's white minivan shortly thereafter 538 00:29:25,306 --> 00:29:28,309 leaving the parking lot at 12:34. 539 00:29:28,351 --> 00:29:33,148 They see Bridget's van returning at 3:19 in the afternoon. 540 00:29:33,189 --> 00:29:36,568 So, you know, a little short of three hours, it was gone. 541 00:29:40,989 --> 00:29:45,952 The murder happened at 2:30, and they'd realized that 542 00:29:45,994 --> 00:29:49,622 that fit into the timeline of when the van was gone, 543 00:29:49,664 --> 00:29:50,999 when the murder happened, 544 00:29:51,041 --> 00:29:54,085 and when the van returned to the workplace. 545 00:29:54,502 --> 00:29:56,379 [Michael] Our confidence was really high that this was 546 00:29:56,421 --> 00:30:00,175 the same van used in the homicide. 547 00:30:00,925 --> 00:30:03,511 [Narrator] But who was driving the van? 548 00:30:03,928 --> 00:30:05,221 [Michael] You can see the van, 549 00:30:05,263 --> 00:30:08,016 but with the angle and the way it's driving, 550 00:30:08,058 --> 00:30:09,642 you don't see who the driver is. 551 00:30:09,684 --> 00:30:13,938 We were wondering if Bridget was involved in this homicide. 552 00:30:13,980 --> 00:30:17,233 Movement Mortgage uses a keycard 553 00:30:17,275 --> 00:30:19,944 to log their people in and out of the building. 554 00:30:19,986 --> 00:30:25,241 We have Bridget's keycard again leaving at 12:33, 555 00:30:25,283 --> 00:30:28,620 and then returning at 3:20. 556 00:30:28,661 --> 00:30:31,289 That is in the timeframe that Michael was murdered. 557 00:30:32,165 --> 00:30:34,459 Bridget told them she never left that day. 558 00:30:34,501 --> 00:30:38,129 Suddenly, their suspicion was focused directly on Bridget. 559 00:30:40,173 --> 00:30:41,383 [Narrator] Coming up... 560 00:30:41,925 --> 00:30:44,135 Investigators

Contrary to what she told police. 577 00:31:44,404 --> 00:31:45,864 [Kent] They decided they should look at 578 00:31:45,905 --> 00:31:47,323 any interior cameras, 579 00:31:47,365 --> 00:31:49,659 that way they could actually establish that 580 00:31:49,701 --> 00:31:51,036 Bridget did in fact leave. 581 00:31:51,077 --> 00:31:53,496 That it was her keycard in her hand when she left. 582 00:31:53,538 --> 00:31:55,206 [Narrator] Investigators view 583 00:31:55,248 --> 00:31:57,709 the interior footage of the cubicles. 584 00:31:57,751 --> 00:32:00,211 [Kent] They're absolutely shocked at what they find. 585 00:32:00,253 --> 00:32:02,839 During the time that her keycard was being scanned, 586 00:32:02,881 --> 00:32:05,675 Bridget is still sitting there eating her lunch. 587 00:32:09,804 --> 00:32:11,598 When they look at the footage, 588 00:32:11,639 --> 00:32:14,726 it's not Bridget that's leaving the building. 589 00:32:14,768 --> 00:32:16,770 It's Kathryn who's leaving the building. 590 00:32:17,604 --> 00:32:20,774 And she's using Bridget's keycard. 591 00:32:22,400 --> 00:32:24,944 [Shawn] Michael was killed around 2:30 in the afternoon. 592 00:32:25,487 --> 00:32:27,238 And then Kathryn is seen walking 593 00:32:27,280 --> 00:32:30,533 right back into Movement Mortgage at 3:20. 594 00:32:31,117 --> 00:32:32,660 They're obviously piecing that together 595 00:32:32,702 --> 00:32:35,205 that it was Kathryn driving Bridget's van. 596 00:32:38,750 --> 00:32:40,794 [Narrator] Over the next 24 hours, 597 00:32:40,835 --> 00:32:43,713 investigators work to find more evidence 598 00:32:43,755 --> 00:32:46,341 connecting Kathryn to the murder. 599 00:32:46,383 --> 00:32:51,262 Detectives obtain a warrant for her cell phone records. 600 00:32:51,304 --> 00:32:52,806 [Terri Jo] By tracking the pings, 601 00:32:52,847 --> 00:32:56,851 they know that she left work shortly after 12:30. 602 00:32:57,686 --> 00:33:00,647 [Shawn] The phone pings near her apartment at 1:16, 603 00:33:00,689 --> 00:33:01,815 and then it shuts off. 604 00:33:02,273 --> 00:33:05,276 The next time the phone pings is at 3:22, 605 00:33:05,318 --> 00:33:07,237 when she's back at Movement Mortgage. 606 00:33:07,696 --> 00:33:10,907 Her phone went dark during the time of Michael's murder. 607 00:33:14,119 --> 00:33:16,788 [Narrator] It appears that Kathryn powered her phone off 608 00:33:16,830 --> 00:33:19,582 during the time the murder was committed... 609 00:33:20,250 --> 00:33:22,293 ...a suspicion that is bolstered by 610 00:33:22,335 --> 00:33:24,504 a search of her work computer. 611 00:33:25,005 --> 00:33:27,799 [Michael] It showed that she had done research about 612 00:33:27,841 --> 00:33:29,217 how to turn her phone off 613 00:33:29,259 --> 00:33:32,512 or hide it so that you could not be tracked. 614 00:33:35,432 --> 00:33:37,392 [Narrator] Four days after the murder, 615 00:33:37,434 --> 00:33:40,311 detectives return to the mortgage company. 616 00:33:40,729 --> 00:33:43,398 They learn Kathryn didn't show up for work, 617 00:33:43,440 --> 00:33:45,150 but Bridget is there. 618 00:33:45,525 --> 00:33:48,361 [Kent] Law enforcement has a suspect, Kathryn. 619 00:33:48,403 --> 00:33:50,363 What they don't know is Bridget's involvement. 620 00:33:50,780 --> 00:33:53,867 So what they decide to do is to press Bridget. 621 00:33:54,951 --> 00:33:57,787 And they start confronting her with the fact that 622 00:33:57,829 --> 00:33:59,748 Kathryn used her ID card. 623 00:33:59,789 --> 00:34:04,544 Kathryn used her vehicle, used her keys to drive. 624 00:34:05,211 --> 00:34:08,214 And she started breaking down and crying. 625 00:34:09,382 --> 00:34:11,426 [Shawn] She didn't know that Kathryn had taken her van 626 00:34:11,468 --> 00:34:15,347 and her card to go in and out. 627 00:34:18,183 --> 00:34:21,519 [Narrator] Bridget admits that she and Kathryn bonded over 628 00:34:21,561 --> 00:34:23,480 their troubled relationships. 629 00:34:23,521 --> 00:34:25,357 She says Kathryn was determined 630 00:34:25,398 --> 00:34:28,109 to keep Michael away from the baby. 631 00:34:28,151 --> 00:34:31,446 Kathryn wanted him to have nothing to do with the baby 632 00:34:31,488 --> 00:34:33,073 if he wasn't gonna be with her. 633 00:34:33,823 --> 00:34:37,869 [Michael] She tried to show herself as being a victim 634 00:34:37,911 --> 00:34:39,287 of their relationship, 635 00:34:39,996 --> 00:34:42,999 saying that Michael was at fault and she was the victim. 636 00:34:43,041 --> 00:34:47,003 Bridget disclosed to me that Kathryn had told her that, 637 00:34:47,045 --> 00:34:48,380 "We are gonna leave these guys, 638 00:34:48,421 --> 00:34:51,466 and we're gonna raise our kids together." 639 00:34:54,260 --> 00:34:58,223 [Narrator] But now that she sees Kathryn's promises were empty, 640 00:34:58,264 --> 00:34:59,599 she feels betrayed. 641 00:35:00,183 --> 00:35:04,938 Kathryn was only using Bridget as a means to an end. 642 00:35:05,605 --> 00:35:08,817 So the detectives ask her whether she'll participate 643 00:35:08,858 --> 00:35:10,485 in a confrontation call. 644 00:35:10,944 --> 00:35:14,781 A confrontation call is when a friend calls the suspect 645 00:35:14,823 --> 00:35:17,283 while law enforcement is sitting there, 646 00:35:17,325 --> 00:35:19,619 recording the entire conversation. 647 00:35:20,620 --> 00:35:23,998 [Narrator] Detectives listen in as Bridget makes the call. 648 00:35:24,666 --> 00:35:26,459 [Terri Jo] During the confrontation call, 649 00:35:26,793 --> 00:35:29,004 Bridget expresses her great concern 650 00:35:29,045 --> 00:35:31,715 about the fact that, you know, the police think that 651 00:35:31,756 --> 00:35:33,800 she may have been in on this. 652 00:35:33,842 --> 00:35:37,595 And Kathryn doesn't seem too concerned. 653 00:35:38,388 --> 00:35:41,474 All Sinkevitch would sit there and say was, 654 00:35:41,516 --> 00:35:43,435 "They can't prove that. 655 00:35:43,476 --> 00:35:45,770 If I did or did not do this." 656 00:35:46,312 --> 00:35:49,607 Then she finally disconnected from the call from Bridget. 657 00:35:51,693 --> 00:35:53,611 [Shawn] Ultimately, because she was willing to 658 00:35:53,653 --> 00:35:55,196 participate in a call, you know, 659 00:35:55,238 --> 00:35:56,614 they eventually believed Bridget. 660 00:35:56,656 --> 00:35:59,451 That she didn't know about what Kathryn has done. 661 00:36:01,995 --> 00:36:03,580 [Narrator] After the call, 662 00:36:03,621 --> 00:36:06,916 Bridget is released and is not charged with any crime. 663 00:36:07,500 --> 00:36:10,170 But Kathryn's statements during the call add to 664 00:36:10,211 --> 00:36:12,339 the mounting evidence against her. 665 00:36:12,756 --> 00:36:15,425 With the surveillance video, the cellphone evidence, 666 00:36:15,467 --> 00:36:17,218 and then the confrontation call, 667 00:36:17,260 --> 00:36:19,137 we've got Kathryn in Bridget's van. 668 00:36:19,471 --> 00:36:20,805 We know we've got motive. 669 00:36:20,847 --> 00:36:23,183 They had enough for an arrest warrant for Kathryn. 670 00:36:23,224 --> 00:36:25,268 [Kent] After being released on the 17th, 671 00:36:25,310 --> 00:36:26,770 Kathryn was not heard from. 672 00:36:26,811 --> 00:36:30,607 Police got a warrant to search her residence. 673 00:36:39,574 --> 00:36:40,867 [Narrator] Armed with the warrant, 674 00:36:40,909 --> 00:36:44,079 Maricopa police set out to arrest Kathryn. 675 00:36:59,386 --> 00:37:01,388 She's not there, the baby's not there. 676 00:37:04,265 --> 00:37:05,725 [Michael] We are looking for Kathryn, 677 00:37:05,767 --> 00:37:07,352 and she's trying to run from us. 678 00:37:07,936 --> 00:37:09,688 The US Marshals Fugitive Task Force 679 00:37:09,729 --> 00:37:11,523 were tracking the movement. 680 00:37:11,564 --> 00:37:13,066 They were developing a plan. 681 00:37:16,611 --> 00:37:18,196 [Narrator] Coming up. 682 00:37:18,238 --> 00:37:21,449 Investigators receive a lead on Kathryn's whereabouts. 683 00:37:21,908 --> 00:37:24,452 Police receive a call from a friend of hers. 684 00:37:24,494 --> 00:37:27,539 They said that she is on her way to his house. 685 00:37:27,580 --> 00:37:30,208 [Narrator] But will it be too late? 686 00:37:30,792 --> 00:37:33,712 She had license plates that she could have swapped out. 687 00:37:33,753 --> 00:37:35,547 [music] 688 00:37:49,060 --> 00:37:51,438 [Narrator] After a five-day investigation 689 00:37:51,479 --> 00:37:53,773 into the murder of Michael Agerter, 690 00:37:53,815 --> 00:37:58,778 authorities are poised to arrest his ex, Kathryn Sinkevitch. 691 00:37:59,779 --> 00:38:03,199 Only Kathryn has disappeared into thin air, 692 00:38:03,241 --> 00:38:05,660 leaving everyone on edge. 693 00:38:06,202 --> 00:38:07,829 We all knew that she did it. 694 00:38:07,871 --> 00:38:10,290 But, you know, we didn't know where she was, 695 00:38:10,331 --> 00:38:11,624 if she was on the run, 696 00:38:11,666 --> 00:38:14,127 if she was gonna come after any of us. 697 00:38:16,838 --> 00:38:19,257 [Narrator] One day after the warrant is issued, 698 00:38:19,299 --> 00:38:21,468 investigators get a break. 699 00:38:21,509 --> 00:38:22,969 [Shawn] Police receive a call 700 00:38:23,011 --> 00:38:25,180 from a friend and former coworker of Kathryn, 701 00:38:25,221 --> 00:38:27,891 says that he's been in contact with her on the phone. 702 00:38:28,933 --> 00:38:31,603 He had just received a phone call from Kathryn, 703 00:38:31,644 --> 00:38:35,940 asking him if he would allow her to stay at his place. 704 00:38:35,982 --> 00:38:39,361 But she said, "Don't look into Michael's death," 705 00:38:39,402 --> 00:38:41,988 which then caused him to want to know why. 706 00:38:42,030 --> 00:38:44,449 So, he's concerned that she might come there and, 707 00:38:44,491 --> 00:38:46,159 and kill him as well. 708 00:38:47,869 --> 00:38:49,496 [Narrator] Law enforcement rushes 709 00:38:49,537 --> 00:38:51,706 to the home in Avondale. 710 00:38:52,165 --> 00:38:57,087 The Fugitive Task Force team rushed in and,

custody of the little baby. 719 00:39:23,863 --> 00:39:28,743 At no time did she ever express any concern for the child. 720 00:39:29,369 --> 00:39:30,912 She was very cold. 721 00:39:32,038 --> 00:39:33,873 [Narrator] Back at the station, 722 00:39:33,915 --> 00:39:38,128 Kathryn maintains her silence and refuses to give a statement. 723 00:39:42,090 --> 00:39:45,635 Kathryn's arrest is good news for Michael's family, 724 00:39:45,677 --> 00:39:49,097 but nothing compares to what comes next. 725 00:39:49,764 --> 00:39:52,726 The paternity results came back that Michael, in fact, 726 00:39:52,767 --> 00:39:55,353 was the baby's father. 727 00:39:56,062 --> 00:39:59,566 Two days after the arrest, Michael's mom, Leslie, 728 00:39:59,607 --> 00:40:01,818 was able to take custody of the child. 729 00:40:01,860 --> 00:40:05,321 [Mark] There was crazy feelings that get bounced around. 730 00:40:05,363 --> 00:40:06,781 That was Michael's son. 731 00:40:06,823 --> 00:40:10,076 But, you know, it's also Kathryn Sinkevitch's son. 732 00:40:10,118 --> 00:40:12,579 You know, in dealing with the whole... 733 00:40:12,620 --> 00:40:15,040 situation of losin' his dad, 734 00:40:15,081 --> 00:40:18,335 we need Michael's son as much as he needs us. 735 00:40:18,376 --> 00:40:20,378 No doubt about that. 736 00:40:20,420 --> 00:40:23,923 [music] 737 00:40:23,965 --> 00:40:28,303 [Narrator] In May 2019, Kathryn's trial begins. 738 00:40:28,345 --> 00:40:32,390 Prosecutors are aware of the obstacles they face. 739 00:40:32,974 --> 00:40:35,352 Obviously, we wish we had the murder weapon. 740 00:40:35,935 --> 00:40:37,270 [Shawn] We don't have a confession. 741 00:40:37,312 --> 00:40:39,939 Almost all evidence is, is circumstantial. 742 00:40:39,981 --> 00:40:42,609 [Narrator] New lab results from Bridget's minivan 743 00:40:42,650 --> 00:40:45,320 bolster the prosecution's case. 744 00:40:45,570 --> 00:40:48,448 It did come back and show that 745 00:40:48,490 --> 00:40:51,826 there was significant gunshot residue in the minivan. 746 00:40:52,327 --> 00:40:55,622 We have her taking a vehicle that was not hers. 747 00:40:55,663 --> 00:40:58,249 We have her driving to her residence 748 00:40:58,291 --> 00:41:01,461 during the middle of a workday when she said she was working, 749 00:41:01,503 --> 00:41:03,171 turned her phone off. 750 00:41:03,672 --> 00:41:07,008 We have GSR results, gunshot residue results. 751 00:41:09,552 --> 00:41:14,099 [Narrator] Prosecutors allege that on December 16th, 2016, 752 00:41:14,516 --> 00:41:18,311 Kathryn stole Bridget's ID card and van keys, 753 00:41:18,353 --> 00:41:20,397 snuck away from work, 754 00:41:21,064 --> 00:41:23,525 waited for Michael to return home, 755 00:41:24,192 --> 00:41:28,238 and then fired three shots into his car. 756 00:41:34,828 --> 00:41:37,664 The final straw for her violence 757 00:41:37,706 --> 00:41:40,417 was, was him pushing for paternity. 758 00:41:40,458 --> 00:41:43,336 [Terri Jo] The defense pretty much put up their argument 759 00:41:43,378 --> 00:41:46,715 that beyond reasonable doubt was not met, 760 00:41:46,756 --> 00:41:48,550 because there was no murder weapon, 761 00:41:48,591 --> 00:41:50,885 and there was no real eyewitness to, 762 00:41:50,927 --> 00:41:52,345 to the killing. 763 00:41:54,014 --> 00:41:58,727 [Narrator] On May 7th, 2019, the jury delivers its verdict... 764 00:41:58,768 --> 00:42:00,061 Guilty. 765 00:42:02,647 --> 00:42:05,775 She was sentenced to natural life in prison without parole. 766 00:42:06,443 --> 00:42:08,987 [Leslie] I absolutely think she got what she deserved. 767 00:42:09,404 --> 00:42:13,074 But I still think that's getting off a little easier. 768 00:42:13,491 --> 00:42:15,994 You know, she can have her family visit her, 769 00:42:16,036 --> 00:42:17,579 call and talk to her. 770 00:42:18,329 --> 00:42:21,916 But at least she's not able to do it to someone else. 771 00:42:25,170 --> 00:42:28,548 [Narrator] The trial brings an end to a painful chapter 772 00:42:28,590 --> 00:42:30,091 for the Agerter family. 773 00:42:30,133 --> 00:42:34,721 But their grief and their love for Michael live on. 774 00:42:34,763 --> 00:42:36,222 There's never closure. 775 00:42:36,264 --> 00:42:40,935 There is figurin' out what you have to do, 776 00:42:40,977 --> 00:42:45,482 how you have to be, to be able to move on and live. 777 00:42:48,360 --> 00:42:52,947 We felt that if Mike had a choice, you know, 778 00:42:53,490 --> 00:42:59,162 he probably would have willingly given his life to save his son. 779 00:42:59,204 --> 00:43:04,501 But by killing Mike, she gave Mike his wish. 780 00:43:04,542 --> 00:43:08,838 You know, he wanted her, wanted the baby away from her, 781 00:43:08,880 --> 00:43:10,382 wanted the baby to be safe. 782 00:43:10,423 --> 00:43:14,302 He's been with us since the day he was eight weeks old. 783 00:43:16,721 --> 00:43:28,858 [music]
