Five strangers brought together by fate...

- Stop it, stop!

Torn apart by a horrific murder.

- Hey.

What the hell?

A teacher with emotional issues...

- Jamie had a history of acting out.

The boyfriend who can't let go...

- Smart-ass college boy with a trust fund.

A brash party girl...

- She plowed through everyone's life

and left destruction behind.

An ex-con looking for a better life...

- Vince was actually a nice guy,

but he just couldn't keep out of trouble.

And a quiet neighbor paralyzed by anxiety.

- More than anything, he wanted to matter.

- I don't get how, in today's day and age,

people let these things happen.

- No, no, hey!

The moment they met,

they were sent

on a "Killision Course."

In April 2011, the convergence of five lives

at a rental house in Stamford, Connecticut,

leads to a brutal slaying...

and it all starts with Jamie Sarno.

- In many ways, Jamie was a classic all-American girl--

a straight-A student in high school,

captain of the track and field team.

She was popular and pretty.

But in college, things changed.

- She led a pretty sheltered, privileged life prior to that,

and in the stress of the real world

she suffered bouts of severe anxiety,

which often manifested itself

in intense emotional outbursts and severe depression.

She was very up and down in her moods,

and she often turned to alcohol to self-medicate.

- But medication and counseling helped.

You know, she held it together and she graduated

with a Master's Degree in Education.

Overall, Jamie was well regarded by her co-workers,

and her students loved her.

But none of them were aware of the emotional instability.

She was able to keep that in check at work.

And it was her boyfriend, Matt Dwyer,

who was forced to take the brunt

of her uncontrollable outbursts.

- Matt Dwyer graduated with a degree in Chemistry,

and he was working as a sales rep

for a major pharmaceutical company.

He was what you'd call the work hard, play hard type.

- Matt's family was middle-class.

He had a fairly typical upbringing,

but his parents were barely on speaking terms.

They divorced shortly after Matt went to college.

- His emotionally starved upbringing had a big impact

on his perception of love and intimacy.

He didn't have a lot of empathy and was completely unaware

of how to cope with emotional outbursts.

- Matt and Jamie met in college,

and by all accounts, they were inseparable.

They had an intense, passionate love for each other.

- It sounded like a roller coaster

of intense fighting and reconciliation.

That kind of relationship typically doesn't last,

but it also doesn't go away easily.

- Neither of them were willing to end the relationship.

So after college, Matt and Jamie moved in together.

But, to be frank,

this was a relationship that was fueled by sex,

which tends to cover up deeper conflicts.

- Get off of me!

- Many troubled relationships

are held together by sexual attraction.

But in the long run,

the underlying flaws in the relationship

become too big to ignore.

After three volatile years,

Jamie can no longer deal with the emotional stress

of the relationship and finally packs her bags.

- What are you doing?

You're not taking the dog.

- Yes, I am.

- Jamie took their dog, Casper, with her.

She had gotten him as a comfort dog

to help ease her anxiety.

She needed him.

That wasn't the first time Jamie had left.

Usually she came back in a night or two.

- Jamie, you're not taking him.

- You're not telling me what to do anymore.

- With their history,

Matt wouldn't have taken Jamie seriously about being over.

He probably just took it

as just another one of her emotional outbursts.

- Jamie!

- But this time it was different.

Jamie didn't plan on coming back.

After Jamie left Matt,

a co-worker suggests she check out the Gates House.

- The Gates House was fairly well known in the area.

It was a rundown mansion that had been converted

into affordable apartments in the '60s.

It was popular among young, single people,

and there was a high turnover.

Most of the tenants

they were trying to escape their past.

- Ask any cop.

If you were ever assigned to District 3,

you definitely answered a complaint at the Gates House.

Probably more than once.

- I didn't really mind living at the Gates House.

It was a temporary thing.

Most of the people were friendly, young.

Sometimes it was fun.

But there was some shady tenants from time to time.

- You could rent an apartment without a credit check.

They offered short-term leases,

so there was high turnover.

Lots of noise complaints, domestic disturbances.

- Ready, Casp?

But before anyone can move into the Gates House,

they need to meet with the property manager,

Vince York.

- Vince was like the dirty rocker type,

but if you were a bad influence,

he didn't want you around.

He did have a soft spot for pretty girls,

which probably started all of the trouble.

- I was Vince's parole officer.

He had a criminal background,

but he was trying to get his life back on track.

His father was serving

a 30-year sentence for manslaughter

after killing a man in a domestic dispute

when Vince was 16.

- Vince had inherited his father's violent temper.

In 2009 Vince was in a bar fight and charged with assault.

Because of his previous record, it was considered a felony,

and he was sentenced to three years in jail.

He got out on good behavior after 9 months,

but was stuck in Stamford on parole.

- The owners of The Gates House

basically took a chance on Vince.

He started just doing odd jobs around the house

to pay his rent.

But when they moved to Florida,

Vince took over as the property manager.

It was a good job for him, kept him busy.

Six months later he was basically running the place,

and that was just five years ago.

It was a great situation.

He lived rent-free, played guitar on the weekends,

and was able to do things on his own terms.

He was gonna keep out of trouble this time.

But then Vince meets Jamie and her dog, Casper.

- Hey, Vince?

I'm Jamie; I called earlier.

- Oh, hey, yeah, Vince.

Oh, you brought a dog.

- There was a pretty strict "no pet" policy

at the Gates House,

and when Jamie showed up with a dog,

Vince should have turned her away,

but he didn't.

- Just bring him in for now, okay?

I'll show you around.

- Okay. - All right?

Jamie has found a new home

and soon discovers that not everyone at the Gates House

is as welcoming as Vince.

- Hi. - Hey.

- I'm Alexis; you must be the new girl.

- Vince may have been the manager,

but the queen bee at the Gates House

was Alexis Carlon.

- Alexis was already living there when I moved in.

Acted like she owned the place.

Nothing went on without her knowing.

She could be pretty nasty if she didn't like you.

- She was your classic mean girl, a bully.

Life hadn't gone her way, and she was mad about it.

She wasn't afraid of confrontation.

She didn't care what people thought,

and that often got her in trouble.

- Alexis was a little older

than the other occupants of the Gates House.

She came from a fairly poor family

and wasn't really close with them.

She hadn't graduated high school,

but she had street smarts.

- She bartended at a local dive bar called Clippers

and actually did pretty well.

She knew how to get big tips.

She could have moved out to a nicer place,

but she didn't.

I think she was only still at the Gates House

because of Vince.

- Um...you know there's no dogs here, right?

- Oh, yeah, Vince said it was fine.

- When Alexis found out

that Vince let Jamie move in with a dog,

she would have suspected he had ulterior motives

for breaking the "no pet" policy.

In Alexis' mind,

the only tenant who should receive

special favors from Vince is her.

- Alexis and Vince had

a friends-with-benefits thing going on,

but I always thought Alexis wanted a lot more from Vince,

something serious.

And he just wasn't interested.

- Vince was interested in trying to get his life back on track.

Alexis wasn't the type of girl

that he would have wanted to get involved with.

She reminded him of his past girlfriends,

who had only caused trouble.

- Hey. - Hey.

- How you doing?

- We had hangouts on the porch most weekends.

That was when I first met Jamie.

Her and Vince seemed to hit it off,

and I knew that was going to end badly.

Alexis believes Vince belongs to her.

However, Jamie's arrival

presents a dangerous new threat.

- Alexis had the type of survival instincts

that often cause more harm than good.

She was very proactive in protecting

what she thought was hers.

Vince definitely fell into that category.

She instantly disliked Jamie.

- Jamie was an attractive girl.

She seemed so sweet and nice and put together.

She represented the life that Vince was striving for

and that would have motivated his attraction to her.

Their first night together ends peacefully...

but could this be the calm before the storm

at the Gates House?

In early spring,

Jamie Sarno has moved into the Gates House

but is unaware that she has disturbed

resident queen bee Alexis,

who has her heart set on building manager Vince.

But Vince may have other plans in mind.

- It was after midnight.

I'm in bed, but then I heard Jamie

screaming at Vince outside.

I remember just thinking, "Oh, lord, here we go again."

- What the hell are you doing outside my window?

- What, I'm fixing the TV dish.

- It was a bit odd.

Vince wasn't the type to work late,

and the way Jamie reacted seemed very over the top.

- The next time I catch you looking in my window,

I'm calling the cops.

- Jamie immediately thought that he was lying.

Being spied on,

a stranger seeing her in such a vulnerable moment,

it was a lot for her to handle.

- And that wouldn't have helped Jamie's feelings

of anxiety and depression.

It probably made her feel emotionally unstable.

Jamie is learning

that when you live at the Gates House,

you never know who to really trust.

- Hey.

- There was this other cute girl named Inez living there

about the time Jamie moved in.

Alexis made sure Inez didn't last long.

Inez and Vince kind of shacked up one night.

No big deal, but Alexis went crazy.

Inez told me all about it.

Inez got nasty crank calls, had her mail stolen,

and then she found her car was all scratched up.

That was it for Inez.

She left.

And that's what Alexis wanted.

- Jamie probably realized then

that moving into the Gates House was the wrong move,

but she wasn't willing to go back to Matt,

so she didn't have a lot of options.

Later that day,

Alexis reasserts her power over Vince.

- Hey, what are you doing?

- I just finished up with Inez's place.

- Oh, Inez.

- Alexis was tired of Vince renting apartments

to attractive young woman,

so she demanded that he rent Inez's apartment to a guy.

- I was thinking that maybe

we could get some men in here, some guys, you know?

- All right, fine.

- Okay.

- That would turn out to be very fateful for all of them.

Vince keeps his word to Alexis

and rents the vacant apartment to 24-year old Ben Oselund.

- Ben seemed like a really nice guy,

good-natured, quiet.

It seemed like a strange fit to me at the time,

but then everyone at the Gates House

had some sort of story.

- Ever since childhood,

Ben had a severe case of social anxiety disorder,

which can badly impair an individual's ability

to function in the world.

Social encounters of any kind

would usually cause a panic attack,

so he learned to avoid them.

- He managed to make a few friends and even got married

to a high-school sweetheart.

- She left him after only a few years.

She had an affair with her boss, who had a lot more money,

and she basically ran away with him.

- It must have been bitterly humiliating and painful.

The only intimate relationship he'd ever had with a woman

had destroyed him emotionally.

That affected him deeply.

- Ben was shy and quiet.

He wasn't very social.

At the time that Ben moved into the Gates House,

he was working as a veterinary technician.

He seemed more interested in animals than people

most of the time.

- Hey, Ben.

Gonna come hang out or what, man?

- Oh, yeah.

At the next porch gathering,

Ben is introduced to the Gates House community

and quickly finds a friend in Jamie.

- Hey, Casper likes you, huh?

- Oh, he's-- he's your dog?

- Yeah, hi, I'm Jamie.

- Oh, I'm Ben.

- Nice to meet you.

- Jamie and Ben hit it off soon as they met.

- Did you make a friend, bud?

- He seemed liked a nice guy,

and Jamie just sort of trusted him

since he was so good with the dog.

The party is about to take an ugly turn.

- Alexis was known for getting pretty drunk

at the porch gatherings,

and it didn't take much

for her to become confrontational.

- Alexis was already feeling threatened by Jamie

because of Vince,

and when Ben and Jamie became friendly, it upset her.

What she saw was another woman getting attention.

It was the type of attention she wanted,

and she lashed out.

- So basically, Alexis just poured a beer over Jamie.

It was out of nowhere.

But I can't say I was surprised.

I think she was just starting her campaign

to get Jamie out of the house.

Jamie is not intimidated by Alexis...

And decides to try to beat her at her own game.

- Jamie had a history of acting out,

and in that moment, in her anger,

she chose to go after Vince,

because she knew how much it would hurt Alexis.

I don't believe she really had any intention

of getting together with him,

and she definitely wasn't thinking

about the consequences.

Vince was very surprised that Jamie was sexting him,

but he wasn't going to tell her to stop.

Jamie and Vince begin

exchanging erotic photos on a regular basis.

For Jamie, it provides a thrill knowing that she has control

over the one man that Alexis wants the most.

But as their sexting continues at night,

Jamie's friendship with Ben grows stronger during the day.

- Jamie and Ben had become close.

He worked odd hours and was around during the day,

so Jamie gave him a key to her apartment

so that he could walk Casper.

- Thank you so much; you're the best.

- Bye. - Bye.

- Everyone in the house could see

Ben had a huge crush on Jamie,

except for Jamie, of course.

Ben thinks he's falling in love with Jamie,

but he fears rejection

and doesn't know how to express his feelings.

- Ben just wasn't Jamie's type.

She needed someone fun and outgoing,

and Ben was just too reserved.

He was nice, but that was all she saw.

After a few nights of texting with Jamie,

Vince is ready to take it to the next level.

And when he knocks on Jamie's door,

Vince gets an unwelcome surprise.

- Matt and Jamie had been broken up

for about a month at that point.

- Vince, this is Matt.

- Matt didn't believe that he and Jamie were over.

He used the dog as a way to get back into her life,

check up on her.

- Should I come back another time?

- Or you could not come back another time.

- Matt made it clear to Vince that Jamie was off limits.

He just saw Vince as a run-of-the-mill,

lowlife womanizer.

- Vince didn't like Matt.

He told me Matt was just a smart-ass college boy

with a corporate job.

I mean, Vince was pretty easy-going,

but he hated that guy on sight.

- I'll text you later.

- Well, he seems nice.

Vince seeks out another outlet

for his growing frustration.

- When Vince didn't get anywhere with Jamie,

he turned to Alexis to get out his sexual frustration,

and she was more than happy to oblige.

Fueled by jealousy and suspicion,

Alexis does what she always does

and checks Vince's phone for signs of an affair.

- Alexis was really jealous when it came to Vince,

so she checked his phone behind his back,

and, lo and behold, her instincts were right.

- She was furious,

and she must have started immediately scheming

how to exact her revenge.

Now that Alexis has proof

of Jamie and Vince's affair,

she begins plotting her brutal revenge.

She won't stop until someone's life is in pieces.

The sordid triangle of sex, lies, and love

between Jamie, Matt, Vince, Alexis, and Ben

creates tension at the Gates House.

Unaware of each other, Ben and Matt both have hope

for a relationship with Jamie,

while Alexis believes Jamie is sleeping with Vince

and has already planned her revenge.

- Alexis entertained herself

by lording over the Gates House.

Alexis decided to distract Jamie by acting friendly,

and all the while knowing what she was about to do to her.

For her part, Jamie wasn't interested

in being friends with Alexis.

She had already shown her true colors.

- Alexis and Jamie were just fire and ice.

Jamie was a college girl, good family, had a nice job.

But Alexis...

well, she was just trashy.

No other way to put it.

- Two-for-one drinks at Clippers tonight.

You should come.

- Alexis would have made Jamie nervous.

She wasn't the type of girl

Jamie would have been used to dealing with,

and she wouldn't have trusted her.

- I can't; I'm busy.

Jamie's instincts not to trust Alexis

are dead on,

and she's about to get a taste

of just how spiteful Alexis can be.

- At the end of May 2011,

just before the end of the school year,

Jamie was called into the principal's office,

and her employment was terminated.

- Please, I need this job.

- It was the pictures that she had sent to Vince.

Someone had gotten email addresses

from the school's website

and sent them to the whole faculty and school staff.

It was obvious that Jamie had taken them herself.

- I didn't send them out, please...

- She was immediately suspended from work

in a very humiliating public way.

Parents, faculty, and even some students saw those pictures.

Jamie's precious career as a teacher

has been destroyed in a single stroke,

and she thinks she knows exactly who to blame.

- Jamie suspected Vince right away.

Who else would have those photos of her?

- You god damn son of a bitch, I should kill you!

- Hey.

Come on, hey!

- At first, Jamie assumed it was Vince,

but later, after we searched Alexis' phone,

there was clear evidence

that she was the one who had done it.

- Alexis, what'd you do?

- Alexis knew how to hurt people,

and she knew that Jamie loved her job.

And she used those photos to destroy her,

probably to drive her out of the Gates House.

- If that bitch can't keep her pants on,

it is no fault of mine.

- What did you do?

Jamie, hey, stop!

The tension between Jamie and Alexis

is escalating to all-out war.

- You are messed up, Alexis!

And so far Alexis is winning.

- The loss of her job would have been devastating to Jamie,

and the extreme stress

would have triggered her anxiety disorder.

She would have become even more emotionally unstable.

When that happened,

we know that she often turned to binge drinking

to numb her feelings.

- Jamie had always relied on Matt in a crisis,

and she texted and called him with no response.

So, in the meantime,

she turned to her only friend, Ben, for support.

- Do you want me to leave?

- No, no, stay.

- Okay.

- She still needed the comfort Matt had provided.

So Ben became his surrogate, at least for the moment.

- You're not gonna take advantage of me, are you?

- No.

The next morning, Matt arrives at her apartment

after receiving multiple texts from Jamie

about losing her job.

- Matt was furious when he found out Jamie

had been sexting other guys.

- God damn it, Jamie.

- He still thought they were

going to reconcile at some point,

and this was not part of his plan.

He also didn't like that Jamie was letting Ben, a stranger,

take care of their dog.

- You know, if you can't handle the dog,

I'm taking him with me.

- What?

- No, stop it, stop.

No, stop it, stop!

- Hey, come back.

- That apparently was the moment

at which Ben Oselund attempted to intervene.

The altercation continued on the front lawn.

- Stop being an ass, come back.

- I'm not being an ass; I'm just taking my dog.

- The argument escalated,

verbally at first, and then physically.

- The dog wants Jamie.

Put him down.

- I'll hand it to Ben.

He really, really stood up for Jamie.

- What, are you a tough guy now?

- Matt!

- Hey!

- You think you're a tough guy?

Come on!

- Stop, Vince!

- Stop being an ass, come back.

All out war has broken out at the Gates House.

Ben tries to stop Matt from taking Jamie's dog.

But, ultimately, it's Vince who stops him.

- During our investigation,

a significant event that we looked into

was a fight that broke out

on the front lawn of the Gates House.

- Vince, stop!

- Before Vince got involved,

the situation may well have resolved itself.

But Vince, with his hair-trigger temper,

took things to the next level.

- Stop!

- We could've arrested Matt, Vince,

or both of them right there,

and in light of what happened, I really wish we had.

But we can't arrest for battery

unless someone files the complaint.

- You want to press charges?

- No.

- If Matt had pressed charges,

Vince would have been in violation of his parole,

and he would have gone back to prison.

- Listen, it's your lucky day, all right?

Don't make me come back here again, all right?

- The cops let it go, so Vince was lucky.

He warned Jamie that if Matt ever showed up

at the Gates House again he would kick her out.

- You bring Matt back here again,

I'm gonna evict your ass.

- Matt didn't have to act right away.

He could have lorded that power over Vince for a while.

I know Vince was afraid of that possibility,

especially since he was so close to being done with his parole.

Alexis, jealous that three men

are fighting for Jamie,

sees an opportunity to wreak even more havoc.

- Hey, hey, let me see.

- She wanted Matt to think Jamie was sleeping with Vince.

Alexis could manipulate people.

She'd make you believe things,

but like it was your idea, not hers.

- Why don't you just come by the bar?

Come by Clippers.

I'll buy you a drink, and we can talk.

- Thanks.

As Alexis digs her claws into Matt,

Jamie attempts damage control.

- Jamie thanked Vince for helping her.

She knew his parole situation

and realized he had risked a lot to help her.

- No, I understand.

I promise, he won't come back.

- Ben overheard Jamie fawning over Vince

and couldn't believe it.

He was the one who'd stuck his neck out for Jamie with Matt,

and Vince got all the thanks.

It was the classic example of the good guy finishing last.

- He would have been very jealous of any interaction

between Vince and Jamie.

- Hey, you okay?

- More than anything, he wanted to matter.

He wanted be important to Jamie.

He'd been completely unimportant

to the only other woman he cared about.

This time, he wanted things to be different.

- Anytime, day or night, just call.

I'll be there.

- Okay. - All right.

That night, Matt takes Alexis up

on her offer for a drink.

- We have witnesses placing Matt at that bar with Alexis,

and credit card reports don't lie.

He went to see her that very same night.

And things quickly become heated.

- Matt had assumed Jamie would come back to him,

but now, after what he'd seen and heard,

he wasn't so sure, and he was furious with Jamie.

- Hooking up with Alexis

was a way of taking back some control.

But it wasn't something that was going to make him happy.

He wanted Jamie,

and even though Alexis was, well, fun,

she was never going to replace Jamie.

- For Alexis, this was just another way

to get back at Jamie.

The next morning, Alexis gets a rude awakening

when she realizes, this time, she has pushed someone too far.

- Jamie did what no one else ever did.

She stood up to Alexis

and confronted her about being fired.

- What the hell did I ever do to you?

- She wanted Alexis to confess to her boss

about what she'd done,

in hopes of getting her job back.

- We don't have a completely reliable account

of that conversation,

but we assume Alexis just owned up.

She probably wanted to twist the knife a little.

- Are we really gonna do this right now?

- Alexis told Jamie that she had slept with Matt

the night before,

and that was when Jamie really lost it.

- Shut up, Alexis!

- Cell phone records indicate that Jamie called Matt

that morning while she was in a confrontation with Alexis.

Jamie tells Matt she knows

about his affair with Alexis and threatens them both.

For Alexis, all of her misdeeds

seem to be catching up with her.

- Get-- what are you doing?

- Why the hell did you tell Jamie about us?

- Matt was furious with Alexis.

He barely knew this woman,

and she had just tried to ruin his chances

of getting back with the woman he loved,

all in the name of her own petty agenda.

- Did you really think that this was all about you?

- You know, you're pathetic.

- At this point Matt was so angry,

he wasn't himself.

He would have been capable of almost anything.

- Stay away from Jamie, or I will hurt you.

Later that same night,

Jamie goes after the one thing in the world

Alexis cares about...

Vince.

- Jamie knew exactly what she needed to do

to get back at Alexis.

She finally took her flirtation with Vince to the next level.

Vince was more than happy

to finally be with the woman he had been wanted to be with

ever since she arrived at the Gates House.

Everyone knew Vince and Jamie hooked up

the moment it happened.

Alexis would have been seething

when she saw Vince and Jamie together.

Vince seemed further than ever from her grasp.

Ben would've been devastated that Jamie chose Vince over him

after he had worked so hard to win her trust and affection.

With tensions at the Gates House boiling over,

it's only a matter of time before blood will be shed.

But the first victim of this tangled web

is the most innocent one of all.

- Casper, come on, time to eat.

Casper ...sper...

Tension at the Gates House is at an all-time high.

Soon after Jamie discovers

her beloved dog, Casper,

dead in the freezer,

police arrive to investigate.

- After spending the night with Vince in his apartment,

Jamie came home to find her dog dead

and stuffed in a plastic bag in the freezer.

She accused Alexis,

and of course we questioned her,

but she denied being involved.

Sad to say, without a witness or forensic evidence,

we had nobody to charge.

- I know it was you, Alexis.

- It was not me.

- I definitely thought Alexis killed that dog.

Jamie sleeping with Vince would have pushed her too far.

- Hey, listen!

No, listen, this stops right now, okay?

This ends today!

Or I evict both of you, you got it?

- It was then that Jamie told Vince

that she wasn't interested in being with him.

We have reason to believe that she intended

to go back to Matt at that point.

- I only slept with you to get Alexis mad.

It's not happening again.

After all the trouble at the Gates House,

Vince thinks about leaving his job for the first time.

- Vince's parole was almost complete,

and his final hearing was coming up.

He had tried to do everything right,

but cops had been at the Gates House

two days in a row.

It was stressful for him.

I advised him to just take off and start over,

ideally somewhere far away.

With Jamie no longer a threat,

Alexis may finally have Vince all to herself.

- Baby, I am so sorry about all this.

- Vince just wanted to get away from everything and everyone.

- Look, I might as well tell you now.

I'm moving to L.A. in two weeks.

- It would have been devastating for her,

especially when she realized

that he wasn't going to invite her to come along.

But the path of destruction that Alexis created

has been for nothing.

She's about to lose Vince forever.

On the other side of the Gates House,

Jamie hopes to put her recent troubles behind her

and start over with Matt.

- Jamie was desperate at that point,

and she was used to turning to Matt

when things got tough.

So she called Matt for help.

- You know, it was my dog, too, Jamie.

It wasn't my fault.

- The person that killed Casper knew exactly

what they were doing to push Jamie over the edge.

She was totally devastated.

She'd lost the one thing that kept her emotionally calm.

- How the hell could you let this happen?

- The fact that Jamie didn't reach out to Ben

as soon as she found her dog is very telling.

Matt was still her emotional go-to

when she became desperate.

- I didn't want this to happen.

- Well, whose fault was it, then?

- It's not my fault.

- Well, it wasn't my fault.

- Matt blamed her for everything,

and she hated him for that.

- Get out!

Go, leave!

- We all heard it.

The house was just an old mansion.

The walls were paper thin.

I mean, they lit into each other like you wouldn't believe.

Jamie is totally alone

and spiraling out of control,

but there is one resident of the Gates House

that still cares for her.

- Ben had overhead the argument, like many other tenants,

and went to check if Jamie was okay.

And, well, she wasn't.

- I messed everything up.

- No, you can't say that.

- He believed he was in love with Jamie,

and he saw her neediness and despair

as a sign of affection towards him.

- Ben had waited a long time for the right moment

to reveal how he felt about Jamie,

but this wasn't it.

- You're so nice.

- She was emotionally fragile, her self-esteem shattered.

She just needed a friend.

- No, Ben, please, you don't want that.

- She rejected him.

Ben is devastated and heartbroken.

- By attempting to be romantic with Jamie in that moment,

Ben forced her to reject him,

which would have only added to her anxiety.

She was definitely near her breaking point.

Once again Jamie feels

like she has nowhere to turn but back to Matt.

- Based on cell phone records,

we know Jamie called Matt around 9:00 that night.

A tenant witnessed him arriving at the Gates House soon after.

The lives of Jamie, Alexis, Vince, Matt, and Ben

are in a web of love, lust, and lies.

And now their uncontrollable conflict

has reached a climax.

- At 9:37 p.m., a 911 call was placed from the Gates House,

reporting that a body had been found in a bathroom

in one of the apartments.

- When I received the body we immediately began

a routine postmortem.

Well, even though the deceased can't speak,

sometimes their remains can tell us

everything about their deaths.

The body can be a treasure trove of evidence

that sometimes just points directly to the killer.

The bitter conflict among these tangled lives

has claimed another life.

But who is the victim?

And who is the killer?

On May 20, 2011,

the body of Jamie Sarno is discovered in her bathtub.

- A 911 call was placed by Ben,

reporting that Jamie Sarno

had committed suicide at the Gates House.

- EMTs responded 12 minutes later,

but by then, Jamie was already dead.

- It appeared she'd slashed her wrists in the bathtub.

At first glance, there was nothing about the scene

that suggested a homicide.

There was no forced entry, no signs of a struggle.

- Jamie was acting more and more irrational,

and she was depressed over the death of her dog,

her relationship with Matt, losing her job.

So it wasn't a stretch

to think that she had decided to take her own life.

But forensic analysis casts that conclusion in doubt.

- During my examination of the body,

I began to doubt Jamie's death was self-inflicted.

The presence of more than residual blood in Jamie's body

indicated that her heart functions ceased

before she bled out entirely.

In other words,

the loss of blood was not the cause of death.

I notified the Criminal Services Unit,

then ordered a toxicology report,

which takes about 72 hours.

Now everyone involved in Jamie's troubled life

is a homicide suspect.

- The first challenge was figuring out

who wasn't a suspect.

- Between the accusations that she had killed Jamie's dog

and the fact that Jamie slept with Vince,

Alexis was definitely considered a person of interest.

- Vince York had a one-night stand with Jamie

just two days before,

and he had felony assault and battery on his rap sheet.

Matt Dwyer was the only one to lawyer up.

It stands out.

- Ben was the only one, other than Vince,

with a key to her apartment.

- But other tenants confirmed

that she gave it to him to take care of her dog.

So that by itself didn't single him out.

But ultimately the most important

piece of evidence comes from Jamie herself.

- I located a small, inflamed pinprick in her underarm,

which suggested to me that she had been injected

with something prior to her death.

The toxicology reports indicated

that the injection was of etorphine.

Jamie's death wasn't a suicide.

She was killed by the injection

of a powerful animal tranquilizer.

- After we got that evidence from the medical examiner,

we moved right in.

Investigators zero in on the suspect

most likely to have access to that particular drug,

the shy and soft-spoken boy next door, Ben Oselund.

- We searched his apartment and found syringes

and vials of the drug

that was used to incapacitate Jamie.

We also found evidence of stalking.

Ben had numerous photos of Jamie

on a wall in his apartment,

a sort of shrine.

He obviously had some sort of obsession with her.

- Ben was disassociated from reality.

In his mind, any act of kindness

or friendship from Jamie

was interpreted as love,

and that turned into obsessive behavior

in a short period of time.

- Ben Oselund was arrested

the same day the DA's office received

the medical examiner's toxicology report.

He confessed everything.

On May 20, 2011,

Ben Oselund entered Jamie's apartment

with the key she had given him.

- He waited until she fell asleep,

injected her, and then staged her suicide in the bathroom.

After placing her body in the tub,

Ben called 911.

- He also confessed to using the same sedative

to kill Jamie's dog.

- He knew that would make Jamie even more vulnerable,

but it backfired when she slept with Vince.

That was probably what made him finally decide to kill her.

- Ben Oselund was convicted of first degree murder.

He's serving a life sentence in prison.

- Shortly after Ben was arrested,

Vince left the Gates House-- and Alexis--behind.

I think he probably finally figured everything out.

- Last I heard, Alexis was still there,

still working at the Clipper,

still holding on to whatever she could.

- Matt succumbed to alcohol abuse.

It seems he was never able to recover from the loss

of the one woman he ever truly loved.

So many people played a part

in this disturbing murder,

and all of them were victims in some way,

every single one.
