[Whitney McGehee] She was strong and tough
and she wasn't going to take anything from nobody.
[Jamie McMillen] She probably had a list of girls
that she went out on a hunt for
every single day to make their lives absolutely miserable.
[Sara Patterson] She was hanging out with the wrong people.
She was preyed upon.
[Amanda Richards speaking]
[Det. Brian Martin] No one could foresee what was going to happen.
This was much more than just a girl fight.
We were terrible bitches to each other
but she was still my friend.
[siren blaring]
[police talking over radio]
[Det. Martin] Shortly before 11:00 p.m.,
the Fort Wayne Police Department
and Fire and Ambulance
responded to a 911 call at Guthrie St.
District officers had previously responded
to this address, hours before
and it was a small party where there was loud music
and a neighbor had called
because they were annoyed by the young people who had gathered.
[Jamie] And the party should have been broken up
but it wasn't.
So now, let's fast forward to 90 minutes later.
[Det. Martin] The police department and medics arrive
and they found a young lady in the driveway.
She was bleeding from the chest.
She was rushed to the Trauma Center in Fort Wayne
to be treated for, what turned out to be, life-threatening injuries.
[Jamie] Fort Wayne is definitely
like an all-American type of your hometown.
And we do your Friday Night Lights here.
Baseball, football.
[narrator] In 2002, Wayne High School
could be ripped from any classic teen movie.
I would say our high school had a lot of cliques.
I feel like it's the same
everywhere in the United States.
You had, like, the stoner kids, the skaters.
Your goth kids.
You had the preppy kids
that wore, you know, Abercrombie & Fitch, Aéropostale,
American Eagle, that type of thing.
[Jamie Duffy] And in any kind of high school,
there are always mean girls.
We made some good memories.
We didn't always make smart decisions.
[narrator] In the Wayne High social hierarchy,
junior Stacy DeGrandchamp
is at the top of the pyramid.
[Sara] Stacy, in high school,
belonged with the preppy kids.
She liked being a part of that group.
She loved her name brands and things like that.
She was always dressed so cute, too.
[Jamie] Stacy loved volleyball,
loved to play volleyball.
She had a very, like, goofy, outgoing personality.
Stacy would frequently trip over her feet,
trying to get to the ball
and she just laughed it off
and she just had the great attitude.
[Jamie] Stacy grew up as an only child.
Her mom was a single mom
and her mom and my mom are twins.
And we always grew up together.
She lived one street down from me.
[Sara] She was so confident and beautiful.
I mean, it was almost, like, looking at a movie star.
You were just like... [gasps] You know?
[narrator] But being a pretty, popular girl
comes with its downsides.
[Rachel] I feel that sometimes she was
too harshly judged by girls.
I know this sounds like such a cliché
but she was so beautiful that
a lot of girls were envious.
[narrator] Some might call her a "Goody two-shoes."
Then, in the spring of 2002,
Stacy meets high school grad
Brandon Muff at a house party.
[Det. Martin] Brandon was approximately 20 years old
and Stacy at age 17,
I think she was, kind of, drawn to the older guy.
Maybe that was a cool thing to do.
Brandon was a bad boy.
[Duffy] Sometimes, you know,
if what you're known is a good girl,
you want to break out of that a little bit.
[Sara] I just knew it was a boy
that was a bit older than us
that Stacy was dating and she was head over heels.
All of a sudden, Stacy wasn't around.
Stacy was hanging out with the group
that was associated with Brandon.
[narrator] That group includes high school party girls,
Amanda Richards and Whitney McGehee.
The part spot was wherever somebody's parents
were not going to be at.
Or wherever they were going to let us
take over their house.
[narrator] The group often ends up
at 16-year-old Holly Boisvert's house,
a queen bee in the neighborhood party scene.
[Whitney] Holly had a pool at her house
and her dad would let us go swimming,
hang out, do whatever.
I mean, we could have 30 kids at their house
and her dad would have been okay with it.
[Jamie] I know that Holly, Whitney and Amanda
were all pretty good friends
and I believe that they were all friends with Brandon.
Amanda was a little bit more quieter
and Holly wanted to be the head of the trio.
[Whitney] Holly could come off as a bully,
or a mean girl, yes,
and if you didn't know how to take her
or understand that, yeah.
But she was fun to be around.
I think that's why we all hung out with her.
[narrator] As Brandon's girlfriend,
Stacy becomes an official member of the party crowd.
But turns out, there's friction between Stacy and Holly
that dates back to middle school.
[Jamie] There was a time when Stacy was in eighth grade
and they all went over to Holly's house.
Stacy had her feet in the water
and Holly made fun of the way
that she was splashing.
"You are prancing around like a little effing princess."
Something to that effect was said
and in front of everybody else
and, so, of course, everybody laughed.
So Stacy got up and left the pool party.
[Whitney] Holly was rough and tough
and she wasn't going to take anything from nobody.
[narrator] By the time Stacy enters Wayne High,
she and Holly seem to have buried the hatchet.
Holly and Stacy both had really strong attitudes,
really strong personalities.
[Natasha Cole] I think that Stacy and Holly were cordial,
they had mutual friends,
but I don't think that she really paid
much attention to Holly.
[narrator] But Stacy's recent addition to their group
touches a nerve for Holly.
[Jamie] Holly dated Brandon
before Stacy dated Brandon.
Brandon and Holly were a thing in the past.
But now, her and Brandon are just friends.
[Jamie] And I think that Holly thought
that she and Brandon would get back together.
[Natasha] I absolutely think that
Holly was jealous of Stacy.
She's beautiful and she has a great sense of humor
and she was dating Brandon.
[narrator] Once again, there's friction between Holly and Stacy,
but this time, Stacy's not walking away.
Stacy felt that Holly was more aggressive
and she brought all this animosity towards Stacy
and Stacy's just like,
"Why are you coming to me,
you know, when I'm his girlfriend now?
You need to just step back."
[Whitney] I don't think Stacy
would have cared enough about Holly
to want to fight her.
But if Holly is going to come at Stacy
and try to fight her,
Stacy's not going to back down
and Stacy is going to stand her ground.
There was a conflict of interest.
I was friends with both of them.
They were both my very good friends.
Now there was a boy in between them
and, then, my friendships with them.
Holly had just expressed to me that she didn't like Stacy,
and Stacy, pretty much, didn't like Holly.
[narrator] These two were headed for a fight
and only one will walk away.
They were pitted against each other,
it almost seemed like, the moment
that they even knew of the other's existence.
[narrator] But soon, Holly's not the only one
who has a beef with Stacy.
Then, me and Stacy got into a fight.
[Det. Martin] Whitney felt that Stacy was talking behind her back,
which, ultimately, led to
just your high school, petty backstabbing.
[Whitney] I think there was a miscommunication
on something that was said
behind my back to my ex-boyfriend.
Apparently, Stacy caused embarrassment
by inferring that Whitney was pining after this boy.
It was something silly that got out of hand.
Whitney had a lot of anger towards Stacy.
[narrator] And Holly was there to stir the pot.
[Natasha] I think that Holly was also jealous
of the friendship between Whitney and Stacy.
And she would have been happy
if there was any beef between their mutual friends.
[Jamie] It's probably Holly putting
imaginary daggers in Stacy's back, meaning,
spreading rumors that probably are not true
about what Stacy said or didn't say.
[Duffy] Rumors and hurt feelings
and gossip and things like that
are the main tools that mean girls use.
[telephone beep]
[Whitney talking over phone]
[Det. Martin] I don't think anybody truly realized
that it was going to escalate to the point that it escalated.
[Whitney talking over phone]
[phone call ending]
[narrator] High school drama is heating up
between Whitney McGehee and Stacy DeGrandchamp,
but it's Holly Boisvert
who is adding fuel to the fire.
[Whitney] Holly, who was wanting everybody
to become enemies with Stacy.
Holly was perfectly fine
with me having a falling out with Stacy.
[Jamie] It's one of those things where
if I'm mad at her,
you're going to be mad at her, too, with me
and that's just the type of person Holly was.
Holly was... She was a mean girl.
She probably had a list of girls
that she went out on a hunt for every single day
to make their lives absolutely miserable
because that was just the type of person she was.
[Natasha] Stacy would not put up with anything
from somebody like Holly threatening her.
[Rachel] Stacy, she would stick up for herself.
She wouldn't pick fights or nothing,
but if she felt like
she needed to stick up for herself,
she would have no problem doing so.
[Sara] Outside looking in
to this group of friends,
that were spending their time with Stacy,
I felt like
she was hanging out with the wrong people.
[narrator] By August of 2002,
Stacy had come to the same conclusion.
[Jamie] Holly was spreading
negative words and rumors about Stacy
just to create more enemies for Stacy.
[Duffy] I think the intensity of the rumors
made her feel like she needed to step back,
and, so, she was just taking a break from it all
because, you know, the mean girl thing
was just getting out of control.
[narrator] Meanwhile, her relationship with Brandon
is falling apart.
[Natasha] I knew that him and Stacy were, kind of, like,
I don't know. They were not in a great place.
[Sara] Life was getting a little bit more serious.
We were going to be seniors.
I think that we were trying to, you know,
think about, like, get a little bit ahead of the game.
[narrator] With only a few weeks left
before the start of senior year at Wayne High,
Stacy makes a big decision.
[Sara] She broke up with Brandon
and stopped hanging out with him.
[Jamie] Stacy was getting ready to go into college
and what her dreams and her future held and it wasn't with him.
[narrator] Stacy makes a break from Brandon and the clique,
except for one new bestie she met over the summer.
Abby Oswald.
[Jamie] Abby was good friends with Brandon
before Stacy and Abby even met.
So Stacy met Abby through Brandon.
Abby and Stacy were very close.
I'd say they had a good friendship.
[Sara] I really didn't know
Abby that well, Abby Oswald.
She wasn't, like, in with our group of friends
as far as like high school went,
but I did notice her coming around more.
I just remember being like, "Who's this chick?"
But not real impressed by her.
I think, even like, a little jealous, annoyed.
That, you know, like, "Here is this new girl
that Stacy's hanging out with."
[Jamie] Stacy was with Abby Oswald.
Stacy and Abby decided
that they were going to go to the mall together.
And she was going to pick out her senior picture outfit.
Later, Abby proposed to Stacy that
they should go to a party.
[narrator] The party's in a run-down neighborhood on Guthrie St.
[Natasha] The house on Guthrie,
it was not our normal scene.
I don't think that that was a very safe place to be.
[narrator] But it's where Brandon lives with his roommate Justin.
I believe that Brandon had asked Abby
when they got done shopping to come by the Guthrie house.
I was told that Brandon wanted Stacy back,
um, even though that's not what she wanted to do.
And Stacy decided that she didn't really want to go.
[narrator] She's concerned that Holly, Amanda
and Whitney might be there.
[Jamie] But somebody had said that
they weren't going to be at the party.
[Duffy] Abby is the kind of girl
that just won't take "no" for an answer.
Abby says, "You've got to come.
You've got to come." Won't take a "no".
And, so, Stacy finally says,
"Yeah, why not? I'll go to the party."
Why not? It's just a party.
[Det. Martin] It is approximately 9:30 in the evening,
when Abby pulls in the driveway with Stacy,
at Justin's home on Guthrie.
And Stacy, as she arrived with her friend Abby, says,
"What is she doing here?"
[Natasha] I don't think she knew
what she was walking into, by any means.
[narrator] On a hot summer night,
Whitney and Amanda decide to stay clear
of the party on Guthrie Street.
[Whitney] If our parents found out that we hung out there,
we would be in really big trouble.
We were going to hang out with another group of friends,
me and Amanda Richards.
[narrator] But riding with them that night
is the queen bee of their group,
Holly Boisvert and she does want to go to the party.
[Whitney] I remember driving over there
and we drop Holly off at the house
and she was supposed to page
when she was ready.
And if she did not page
before we left where we were going,
then we would just come back and pick her up.
[narrator] Whitney and Amanda never get a page from Holly.
So they head back to Brandon's house around 11:30,
to pick her up as planned.
[police talking over radio]
[Whitney] When we pull up to the house,
there is police and ambulance everywhere.
The whole block was pretty much shut down by police.
[narrator] Just 30 minutes earlier,
a young woman is rushed to the hospital.
A group of teens are gathered outside.
Abby Oswald tells detectives what happened.
[Det. Martin] Brandon and Holly
they were sitting on the front porch together,
when Abby and Stacy first pulled up.
And Stacy sees Holly and says,
"What is she doing here?"
Holly and Stacy have a verbal argument.
[Duffy] Within 10 minutes of Stacy DeGrandchamp's arrival,
she and Holly are in a shouting match together.
Eventually they are fighting with each other.
There is hair pulling,
there is punching, there is kicking.
They are rolling around on the grass.
[Jamie] Holly had every intention on going out there
and giving Stacy a beating,
but Stacy was beating her pretty bad.
[Det. Martin] Stacy was getting the best of Holly,
to the point where she was kicking Holly
in the head or in the face.
[Duffy] Then, all of a sudden,
it seems as though Stacy is going limp
and losing her strength.
And that's when Brandon decided to reach down
and pull Stacy away from Holly.
[narrator] Brandon grabs Stacy by the ankles
and pulls her into some recycling bins in the yard.
Stacy gets up and staggers down the driveway.
Abby says, "Let's get out of here."
And as Stacy is walking around
to the passenger's side of the vehicle, she collapses.
She appeared to be having some type of seizure.
Abby runs over to her,
to try and figure out what's wrong.
[Det. Martin] Brandon came over almost immediately
and pulled up Stacy's shirt
and noticed that her bra was saturated with blood.
[sirens blaring]
[Det. Martin] Stacy DeGrandchamp was put in
the back of the ambulance
and rushed to the hospital.
I don't think anybody at that party realized, initially,
that Stacy was hurt as bad as she was.
Holly and Brandon were taken
from the scene to the police station.
When crime scene units arrive,
crime scene tape is up.
They began taking photographs and videotaping the scene.
[narrator] Since Stacy was bleeding from the chest,
investigators look for weapons.
Detectives did not observe any sharp-type objects,
knives or anything of that type
in the backyard or driveway of the residence
as they had presumed,
possibly, it would be in the area
of where the girls fought and struggled on the ground.
They went into the residence,
after obtaining a search warrant,
and they took some kitchen knives
that were laying on the counter.
[narrator] In the operating room at Parkview Hospital,
doctors are working to save Stacy's life.
[Det. Martin] She sustained a stab wound
to the upper chest area,
in the area of her breast
and she also had a second stab wound
to her abdomen area.
Rita, Stacy's mom, didn't know that
something happened to Stacy.
She gets the voice message around 11 o'clock.
It's from Brandon.
-[telephone beeps] -[Brandon talks on phone]
[Jamie] Rita gets to Parkview, Randallia Hospital
to only be approached by the hospitalist.
She said, "Oh, you're Stacy DeGrandchamp's mother?"
And Rita answered, "Yes," and they said,
"Well, unfortunately, she's passed away."
[Sara] It breaks my heart.
Oh, sorry.
[chuckles] Sorry.
It's something I haven't thought about it in a long time.
[sniffling]
Oh, I can't imagine having to go and do that with your only child.
[sobs softly]
We had so many questions, and no answers.
[narrator] Because the stab wounds appear intentional,
Fort Wayne police open a homicide investigation.
At the station,
Holly shares her version of events.
[Det. Martin] Holly stated that
she had nothing to do with, uh, the injuries
that took place to Stacy,
that they'd merely gotten into an, an argument, or a fight.
[Duffy] But, of course,
very important,
Holly said, she had no knife.
[Det. Martin] She says she believes that Stacy
might have fallen on glass in the recycling bins.
[Det. Martin] Detectives also interviewed Brandon.
[narrator] His shirt, stained with Stacy's blood,
has been taken as evidence.
[no audio]
[Det. Martin] He was trying to allude to the fact that
Stacy's injuries being caused by
cut or broken glass, or glass shards
that were in the recycle bin that she fell into.
[narrator] But Holly and Brandon's stories
don't match up to the evidence.
[Det. Martin] Crime scene took photographs of the recycle bins,
and there was no broken glass.
There was no marks that glass had been swept up,
There was no blood,
in our around the recycle tubs.
It was very clear from the coroner's report
that those injuries were sustained,
and inflicted,
by a single edge, sharp, bladed knife.
They were described as knife wounds.
But the knife was not located at the scene,
or on any potential suspects at the time.
[narrator] Holly and Brandon are released.
But this remains an open homicide investigation.
On August 19th, 2002,
Stacy DeGrandchamp is laid to rest.
She's buried in her senior outfit
that she was supposed to do senior pictures in.
[narrator] It's a full house,
including Stacy's friends from the party crowd,
Abby, Whitney, and Amanda.
Holly Boisvert is notably absent.
[Jamie] We had teachers there.
She had a lot of her classmates that came.
Coaches.
But one
person showed up that, in my mind,
was not invited to come to that funeral.
Brandon Muff showed up.
And, all eyes are on him.
We couldn't believe that he had
the guts to show up.
We felt he had something to do with this.
[narrator] Rumors are spreading through Wayne High School,
that Brandon and his friends
tricked Stacy into coming to the party,
so Holly could hurt her.
[Det. Martin] It leads the detectives to wonder,
was this a conspiracy
to have one of the girls eliminate the other.
I do believe that Stacy was led into a trap.
They knew what was gonna happen that night.
After Stacy's death,
nobody was going to hang out with Holly.
Holly called my house.
I remember talking to her,
and in the conversation, said, "How could you do this?"
and she said, "You know me,
you know I would never do this."
And, then...
I never talked to her again.
The rumor mill, when school stated back up,
it was all over the place,
as far as what took place at the party.
[Rachel] The only common thread was
Holly stabbed her, Holly killed her.
That was the common thread.
[narrator] But another rumor makes its way to police.
Whitney had something to do with it.
[answer machine beeps]
For a detective to hear a voicemail like we heard,
that was given to us by Rita, Stacy's mother,
where somebody is saying, "You better watch your back",
and then,
in very, uh, short time,
that individual is, is killed,
uh, it's very concerning.
[knock on door]
[Whitney] The detective came to my house,
to interview me there.
[Det. Martin] We have to ask her why exactly she left this message,
and eliminate or include her as a potential suspect
in Stacy's homicide, whether she had a role of setting it up.
[Whitney] The message was never, ever a threat, it was...
A warning, so that she knew to watch out for herself,
because I knew that Holly wanted to fight her.
So, Stacy needs to know that Holly is mad,
because I didn't want them to end up
at the same place, at the same time.
[narrator] But if Whitney was trying to keep Holly and Stacy apart,
it appears Brandon
was actively trying to set them on a collision course.
[Det. Martin] Detectives learned through Whitney,
that on August the 15th,
Brandon had called over to Holly's house,
and said, "If you don't come over to this party, over on Guthrie,
then I'll never speak to you again."
[Whitney] I thought they were just gonna hang out and talk,
I had no idea that Stacy was going to even be at the party.
[Det. Martin] So detectives had to try to figure out
if this was some sort of trap that was, uh,
laid out by Brandon to get both girls at the house to fight.
I'm sure it absolutely hurt Brandon's ego
that Stacy broke up with him.
Was he working to get even with her,
maybe there was a little bit of revenge on his part,
in this whole affair.
[Whitney] Holly's jealousy and Brandon's spite
is what got them both there.
[narrator] But there is another person who is key
in persuading Stacy to go the party that night,
her new friend, Abby Oswald.
I think that Abby insisting that Stacy go to that party
is because Abby was friends with Brandon.
From a detective's point of view,
I wondered why
Abby would bring her friend over to the Guthrie St. house,
knowing that there's a possibility
that Holly was there, or...
As they were pulling up, seeing Holly,
and knowing the tension,
why she didn't just say, "Hey, now's not the time, let's leave."
[Sara] My suspicion at the time,
was that Abby was a part of the...
The game plan to get Stacy there,
to the party.
Whether that was actually driving,
talking her into going,
I think that is the part that Abby had played.
[narrator] But when detectives speak to Abby,
she denies any involvement.
Abby also said that she was the one
who tried to break up the fight.
[narrator] With all roads leading back to Brandon,
detectives call in his roommate from Guthrie St.,
Justin Troop.
[Det. Martin] The interview with Justin to law enforcement
was on the 26th of August.
Justin appeared to be a very credible witness.
According to Justin's account,
he tried to break the fight up, between Stacy and Holly.
And Brandon pushes him aside,
and says, "No, let them fight."
It's almost as if Brandon is enjoying the fight.
[Duffy] So, did he set it up? Possibly.
Did Brandon intend for any harm to come to Stacy?
That's tougher to prove,
and harder to say.
[Det. Martin] Justin was able to tell law enforcement
that Brandon made the statement,
"Just tell them",
referring to the police,
that Holly didn't do anything,
and that Stacy just fell.
It made law enforcement very suspicious
that maybe Brandon had more,
uh, solid information,
but was just not bringing it forward to law enforcement.
Whether he was afraid, whether he was trying to
stonewall the investigation,
or whether he was attempting to
cover for Holly.
Brandon was, uh, ultimately interviewed a second time
and it was during the course of this interview
that Brandon refused to give any other information.
Brandon made the comment to law enforcement,
to the detectives, that he, uh, "was no snitch",
and that he did not see Holly with a knife.
[narrator] But to many, one thing is certain.
They fought, it's clear as day,
that Holly did it, like, it's clear as day.
To us, it was, "She murdered Stacy."
We-We've got our killer.
I thought, within three to four months,
we would be in court, and I would watch her, in my mind,
get the death penalty, you know,
like, I was going to actually see justice.
It's normal to
think, they're going to keep interviewing,
and they are going to be able to find
a couple witnesses that are willing to speak.
Just one, just one witness.
And of all these people that were at this party that night,
not one person was willing to come forward
and say that they'd seen something.
[narrator] With no witnesses, and no murder weapon,
there are no arrests made.
[Jamie] Months upon months upon months,
no phone calls back, then, you know,
days turn into years.
We were extremely discouraged, I mean,
you can only imagine after all those years
of trying to get justice, that,
it just won't ever come.
[narrator] But sometimes, justice comes from the most unlikely places.
[narrator] By 2019,
students at Wayne High have heard the story for 17 years.
If you're mean enough,
you can get away with murder.
It felt like Stacy's case was on the backburner,
and nothing was being done,
and nobody understood why.
[narrator] But, Stacy's cousin
Jamie McMillen refuses to let the case die.
She finally connects with cold case detective, Brian Martin.
[Det. Martin] In March of 2019,
I received a telephone call from Jamie McMillen.
Jamie was wanting to speak to me about her cousin's case.
[Jamie] When Detective Martin called me back,
I thought, "Okay, this is a step in the right direction."
Jamie believed that if I would be able to talk to Brandon,
Holly, Abby, and Amanda,
that I would probably be able to get the answers
to the questions that we'd been looking for all along.
There is a benefit to the cold cases,
and interviewing witnesses.
Maybe they've gotten older, matured,
gotten out of that lifestyle and are more willing to talk to us.
[narrator] Detective Martin first tracks down Abby Oswald.
[Det. Martin] Let me ask you this,
-at any time, did you see Holly with a knife? -No.
I never saw a weapon, that's why this is so hard
-and why I-- -You just thought it was like a fight...
-Yes, yeah. -...in a yard, and then all of a sudden,
-this happens? -Yeah, and like her mom, we, you know,
when we were talking after the fact,
she then wanted me to say, "I saw a weapon", or, "I know something".
But I can't sit here and say, "I saw a weapon"...
-Don't. -..."I saw a knife", when I didn't.
[narrator] Detective Martin then speaks to Brandon Muff,
who says he wishes he saw more.
[Det. Martin] I observed Brandon to be, uh...
He was remorseful.
He, you could tell this has been weighing on Brandon
for 17 years.
But he doesn't recall seeing Holly with a knife.
Approximately one month after speaking with Brandon Muff and Abby,
I was able to track down Holly Boisvert,
in Fond du Lac, Wisconsin.
-[knocks on door] -[door opens]
[Det. Martin] It took Holly quite a while to answer the door, but when she did,
I introduced myself as, uh, Detective Martin from Fort Wayne,
and, I was working on a cold case.
The look on her face, she was, uh...
She got rather pale.
I indicated that I knew that it'd been some time,
and I asked her if she remembered the party.
Nothing makes sense,
about the whole thing.
[Det. Martin] How so?
Everybody there, we were all friends.
-I mean, it was-- -[Det. Martin] But, you and Stacy had,
kinda had a little beef going on, because of Brandon.
-It was so stupid, that was-- -[Det. Martin] It was, uh, it...
I agree, it was like one of those just,
-petty, high school girl things, right? -Exactly.
-[Det. Martin] Okay, so... -I know everybody says that
I did something to her, I know that they blame me.
[Det. Martin] There were several things that, uh, really stuck out to me.
First and foremost, she kept referring
to Stacy as her friend.
She was my friend, we were terrible teenage girls,
but she was still my friend.
"And I would never intentionally stab my friend."
I would not have done that to her.
Intentionally, I never would've pulled a knife on her.
We were terrible bitches to each other, but she was still my friend.
I didn't expect that we were gonna fight.
[narrator] Holly admits to owning a pocket knife at the time,
saying she carried it around for protection.
[Det. Martin] Do you recall,
did you have, uh, your pocket knife with you that day?
I didn't even have it with me,
like, if it was there, it was in my bag,
it's not like I walk around holding it.
[Det. Martin] Have you seen it recently, do you have it now?
Uh, let me...
[softly] Let me look somewhere.
And she got up, and she went back to a bedroom area.
What's crossing my mind when Holly hands me this knife is,
one, is she trying to throw me off of what's really happening,
and where that knife really is,
or two, did I catch her in a moment of weakness,
and she actually gave me the knife
used to kill Stacy?
I then returned back to Fort Wayne, and began
putting information together in the case.
[narrator] While test results show that Stacy's DNA
is not on Holly's knife,
Detective Martin does further testing on the weapon.
I ultimately showed this pocket knife
to the chief pathologist who investigated this case.
[Duffy] Dr. Scott-Wagner reviewed the autopsy photos,
and came to the conclusion
that the knife Holly Boisvert turned over to Brian Martin,
was consistent with the stab wounds
that DeGrandchamp received.
That information, along with information
from the initial investigation,
began to get us to a point where we were able to
present this case to the Prosecutor's office.
[Duffy] On Wednesday, March 25th of 2020,
Holly Boisvert was taken into custody.
[Sara] To get her just even back to Indiana,
and in Fort Wayne's jail,
was just like, holy, you know what, like, this is...
You know, it's the first time that
I felt like
Stacy might actually get justice.
The pre-trial conferences were conducted by
the Allen County Prosecutor's Office.
[narrator] After years of silence from the group of friends,
a star witness finally decides to come forward,
Amanda Richards,
who was in the car with Holly and Whitney the night of the party.
And one of the last things Amanda remembers doing
is handing Holly her knife,
and Holly walking up to the house.
[Whitney] I was in the car, I didn't even know Holly
and Amanda has exchanged a knife.
[Det. Martin] I can't speak to why Amanda
waited so long to bring that information out,
I'm just thankful that she did.
[narrator] In consultation with Stacy's family,
Allen County offers Holly Boisvert a plea deal.
[Det. Martin] Holly ultimately acknowledged the fact that
she did, in fact, stab Stacy, causing her death.
[narrator] Holly never implicates Brandon, or Abby.
She insists she acted on her own.
[Jamie] She just sat there and stated,
to the judge that she had killed Stacy DeGrandchamp,
and he said then, "How did you do it?"
And she said, "I had a knife in my hand,
and I stabbed her once here",
and she said, "and I stabbed her once here."
He said, "And how would you like to plead?"
And she said, "Guilty."
[Whitney] I was emotional.
It hit me hard,
that finally...
Finally, she admitted to it.
[Duffy] Holly was sentenced on January 14th of 2022.
The plea deal called for 25 years, with five years suspended,
and three years of adult probation following it.
[narrator] With time already spent in jail and good behavior,
Holly could be out of prison as early as 2030.
[Jamie] I absolutely believe that Holly should've gotten more time.
I felt, at least, the full 20 years,
behind bars.
[Det. Martin] To me, I think closure, uh,
quite frankly is [bleep].
Um, and I say that because
I don't how you can have a loved one
taken from you in a violent manner,
for no reason at all,
and ever be able to, uh,
wrap your brain around how and why that happened.
[narrator] Even all these years later,
Stacy's friends and family can't fathom
how teen mean girl drama
turned so deadly.
I think the most important piece of it all
is that life is so fragile and can be taken at any point in time.
And even, something senseless over a a boy
or over, just, being upset about rumors.
There are families that never get justice for their lost loved ones,
and so, at least,
Stacy got something.
I wrote a poem for Stacy,
and, um, they actually published it inside her yearbook
for Wayne High School for 2003 graduating class,
which would've been her.
And I actually have it here,
"Her eyes so bright her smile so wide
we always let her know that we are right by her side,
so never forget her never let her leave your mind,
tell her you love her just one more time."
