Previously on CSI: Vegas...
Three cases we've worked on in the last few weeks?
They're all connected.
CHAVEZ: Richard Sloan? Anyone home?
RAJAN: Stop!
Sloan's being manipulated by somebody.
I mean, odds are it's the same person behind all of it.
BRYAN: A guy told me that you were attacked,
put in the hospital and nearly died.
You sleeping okay? Since your attack?
I know nights can be the hardest part.
You're the most important person in my life here.
But you're with Chavez now.
We can't be friends.

That is a lot of blood.
Halfway to a paint job.
CHAVEZ: Maybe we'll catch a break,
and this guy live-streamed his own murder.
You never know.
Something Nateorious would do.
The vic, @ItsNateorious?
I'm not familiar.
I knew I liked you.
Nate and his friends, the kids who found him,
they're all social media influencers.
Basically, professional narcissists.
You sure none of them are lumberjacks?
Boy.
Somebody really didn't like this guy.
That looks like at least four deep slashes
to the throat.
Empty solo cup.
I wonder if he was passed out when they got him.
Would explain the lack of defensive wounds.
Well, could be bruising we can't see.
I'm gonna switch to infrared for a sub-dermal look.
No bruising on the hands or forearms.
Serena?
Oh, man.
That's not good.
All right, maybe this is something.
Unsolved homicide in Henderson.
Case number 16-90030.
Housewife's head got smashed
into a full-length mirror in 2016.
Hmm, it's a little dusty.
Do you think there's some connection one of our perps
or victims from the Silver Ink cases?
Nothing solid, but...
mirror as a murder weapon.
RAJAN: Shades of Alan Herskovitz.
I mean, it's worth a look.
Uh, Allie?
Isn't this your day off?
Yeah. I just, I thought I'd come in
and look for some new leads.
See if there's any related cases we might find.
And did you find any?
Nope.
Okay.
So you go home, you come with me.
Boss, can I just--
Allie, I appreciate your hard work.
But we don't have an open case.
It's been three weeks
and I need you working on active files.
And I need you rested.
Personally, I find this place very peaceful.
Okay, stay.
Hey, come on.
Where to?
Joshua caught a juicy one in Green Valley.
And he asked for you by name.
Somebody call for the cavalry?
Something like that.
Heard I was your first choice. I'm flattered.
This one has Chris written all over it.
Blood spatter central and it's very reminiscent
of one of your how-to videos.
This about your @Chrissolves thingy?
Hey, it's just a side hustle.
Slice of CSI life, forensics I find cool.
I never post about anything confidential or sensitive.
No big deal.
FOLSOM: Don't undersell it, Chris.
No big deal.
FOLSOM: Don't undersell it, Chris.
It's getting to be a big deal.
How big?
You've got a hundred thousand followers?
112,126.
How much time you spending on this?
None at work, I swear.
Chavez really enjoyed "What To Expect When Dating a CSI."
Thanks for that.
All right.
So you asked for him specifically. Why?
Because the killer did, too.
You're gonna want to see this.
Killer wrote your handle in... something.
It really pops under black light.
Sodium carbonate.
I did a post on invisible ink last week.
Somebody's been paying attention.
And now they want you to pay attention to them.
PARK: It's worse than you think.
I know this guy.

Boss, please.
You got to let me work this case.
The killer wrote your name on the victim's face.
What if he'd written all of our names?
Would the entire crime lab be disqualified?
That's a nice way to get away with murder.
Man has a point.
No, he doesn't.
The victim, Nate?
It's not like I knew him personally.
I knew of him, but, then again,
a lot of people do. He has close
to three million followers.
Had close to three million followers.
ROBY: I guess we can't have killers
kicking us off cases, huh?
You can work it, but you're riding shotgun.
You're point. Come on, what's going on here?
Tell me about Mr. Popular and all his friends.
I think it's some sort of...
weird revenge thing. Four years ago,
Nate was charged with killing a woman with an axe.
I knew his name sounded familiar.
Not me. I was in Chicago.
My whole class at the academy was, like, obsessed
with the entire trial. It was Nate
and his roommate, Warren, who were accused.
Two young guys like me-- you know, "extremely online."
Cops said that they killed their neighbor.
Ana Reynolds. Someone slashed her throat.
FOLSOM: Just like today.
PARK: Warren's boot prints were found
in Ana's yard.
ROBY: Mm-hmm.
Nate's camping axe turned up in the dishwasher.
Bleached. They said that the stab wounds
matched the axe's pick end, but...
ROBY: They beat a murder charge.
I might've had a little something to do with that.
I, uh, made a video about the murder
and it sort of went viral.
How do you "sort of" go viral?
Fine. It completely blew up.
Show me.
Come on, show me.
Axe murders are crazy and nasty
and out of control.
But the castoff is way more boring
and predictable, and nothing like
what we saw in the leaked crime photos.
The cops found blood ten feet above Ms. Reynolds.
Why? How'd it get there?
No way an axe did that, chief.
Nothing in this case adds up.
I don't think Nate and Warren did it.
You posted
about an ongoing murder trial?
There are rules about this exact thing.
Wait, this was before I was a CSI.
Yeah, but look.
You're still posting.
I mean, like... like, a ton of them.
Never about an ongoing case.
Not since you hired me.
Look, I was right.
A few days after I posted this, I got DM'd by Greg Sanders.
I remember Greg. I mean, did you two
overlap at the lab?
He left before I started, but the point is,
he had a lot of the same questions about Ana's case.
But the D.A. was overzealous.
Took the whole thing to trial before
anyone could figure out what really happened.
But you figured out what didn't happen.
Nate and Warren's lawyers actually
used my theory in court.
It's probably what got them the acquittal.
I got a lot of flak from other armchair detectives,
but I was right.
An axe like this
just does not explain
the spatter around Ana Reynolds.
What, is that the same type of axe?
Actually, I-I...
I think it's the exact same axe.
FOLSOM: No. You think he just had
it lying around, his old murder weapon?
Alleged murder weapon.
I just do not like the look of this.
A vengeance killing.
Someone mad at you about a trial.
We are talking about something that,
that could be dangerous for you, Chris.
Nobody knows Nate Taylor's case better than I do.
LVPD will review your social media.
And, uh, if they find anything--
They won't.
And, uh, if they find anything--
They won't.
Okay, you two keep processing up here.
And I'll make sure we're collecting
DNA from Nate's housemates.
You know, I never needed a reason to avoid social media,
but I... appreciate you inventing a new one.
So, like, physically, I was here last night.
But psychically, I was on a whole other plane.
Yeah. I've read about astral projection.
I don't think it's widely recognized as a viable alibi.
Uh, fair warning, my dude, my DNA is copyright protected.
Like, legally.
I'm not sure how to respond to that, either.
Warren, you let us know
when we have your attention, huh?
You got to get those likes, huh, Warren?
My best friend was just murdered.
Okay? Nate was, like...
he was, like, a legend.
I'm devastated.
And I have to share my pain.
Emotional honesty, that's my brand.
Does your brand have an alibi?
Yeah, I was out last night.
So we had this little pre-party
at the new club at the Bellagio.
I got so messed up that by the time
we got back, I-I missed our own shindig.
I went straight to bed.
That's not exactly an alibi.
Okay, fine, but...
it's the truth.
I didn't think you'd be a wristband buddy.
Come on, what club were you at?
ROBY: Oh, this isn't from a club.
I got hit on the head a while back.
It's a nasty business, trying to cover up for murder.
So I was partying at WLVU Medical Center.
But, hey, better drugs there.
Uh, let's get specific, Warren.
What time did you get home last night?
Uh...
probably like...
lawyer o'clock.
Excuse me?
I've been through this before.
Okay? You've probably heard about me.
I'm Warren Bart. I was falsely accused of murder.
I'm zipping my lips.
I'm not saying another word without my attorney present.
Thanks, gents.
Honestly, I don't see how anyone could've done this.
Look.
Those footprints are Nate's,
we made the rest, but the killer didn't leave any?
How is that possible?
It gets weirder.
How is that possible?
It gets weirder.
Look at the spatter pattern, what do you see?
Uh, blood. Everywhere.
FOLSOM: You'd expect to see a break in the blood
where the killer was standing, right?
But there's no break.
There's no void.
Almost as if Nate was alone
on the balcony when his throat was slit.
Right. So how does a killer leave behind
a murder weapon and a body,
but not a single trace that he was ever here?
I don't know.
It's like he was killed by Batman.
Oh.
Sorry to interrupt. I-I just, I'm expecting some...
It's okay.
You work here. You don't have to apologize.
Hey, Beau told me
that you guys got to meet some e-celebs
whilst you was out on the scene.
Must have been exciting for you.
Well, I quit Myspace and never looked back.
Sometimes I forget you're kind of ancient.
Oh.
It's all Nate's blood. If the killer got nicked
swinging that axe,
he didn't leave any on the blade.
There's no prints either.
Really?
FOLSOM: Wait, wait, wait, wait a second.
Wait, go back to your left.
What are those white crystals?
Sort of looks like salt.
Do you think the killer could've sweat onto the axe?
Gloves don't cover the whole arm.
If there's sweat, there's DNA.
Thanks.
So you're as millennial as Chris.
You hiding some secret
internet following, too?
I lurk. I browse.
But nope.
I'd rather not have my life
under the scope for everyone.
I don't see the attraction.
I guess Chris does.
He wanted to be an influencer
before he put the lab coat on.
I think... I think he likes the attention.
VINCENT: In case you're living
under a rock, @ChrisSolves
may finally be taking the L he so richly deserves.
Now some of us have always known that Warren Bart is a killer.
We didn't need him dropping a second body to confirm that.
But not @ChrisSolves, no, you see, he is dedicated
to once again helping the guilty.
Not sure that's the healthiest use of your time, my friend.
Nate's murder is trending. And everyone's talking
about the old Ana Reynolds case again.
This is why I tell my daughters they'll get a car
before they get Instagram.
Don't you think that'll just make them want it more?
That's what spyware is for.
Oh.
You're that dad.
#ThatDad.
Wait, I got to go.
Allie ID'd the guy who sweat on the axe handle.
Really?
Well, who was it?
ROBY: Okay, Warren.
Why was your sweat on that camping axe?
Sorry, Dr. Roby, but the scope
of your warrant is limited to a blood draw.
My client isn't compelled to answer any of your questions.
I thought he'd like a chance to explain why the axe
that was at the center of the Ana Reynolds murder case
was still in his house.
SMITHERMAN: I appreciate your curiosity.
But he's not answering any questions.
You folks falsely accused him once before.
If Ms. Willows was in town to explain herself--
It doesn't matter. What matters is you have
what you need, and we're leaving.
Mr. Bart.
PARK: Wait, wait.
Warren, wait.
We're trying to find the person that killed your best friend.
I know you can help us.
No, you need to help me, dude.
You found me innocent once.
You got to do it again.
I didn't kill Nate.
Then who did?
I don't know. I don't. Dude...
My client has nothing more to offer.
You have his DNA on an implement
you found in his house.
That's all you have.
That's all you'll ever have.
He's innocent.
We'll see.
I can tell you one thing about this killer.
He hates subclavian arteries.
This one got severed in four different places.
Hmm. Brutal.
Extremely. You want to see something wild?
The blood vessels in his conjunctiva flared.
That's... wild?
Well, it's not every day you see trauma so pronounced
that it enflames the membrane over the eye.
There's a new nightmare.
The lack of defensive wounds is a lot less surprising.
Tox showed blood alcohol was at 0.185,
and he had 260 milligrams per liter
of gamma hydroxybutyrate in his system.
That's a lot of GHB.
If the killer was planning ahead, maybe he drugged him.
Some people do take it recreationally.
Ugh. These kids today.
Anyway, I'm just getting started here.
But barring any surprises, I think we all know the cause.
The killer struck Mr. Taylor's neck
with so much force that it left grooves in
his clavicle and first rib here and here.
Wounds generally consistent with an axe.
FOLSOM: "Generally consistent"
is not what we're here for.
What? You want to start with tool mark analysis?
Better we check the grooves in his bones
before you make the "Y" incision.
Warren Bart has a great attorney, and a history
of tap-dancing his way out of murder charges.
We can't leave any doubt
that those wounds
were inflicted by this axe.
Well, then...
swing away.
♪ ♪
FOLSOM: Okay.
Let's try a different angle.
Yep.
Sonya?
Yep.
Let's try the other side of the axe.
Yeah.
PARK: It's not a question of what angle
or what part of the blade.
Nothing matches. There's no way
that that axe left those marks on Nate's neck.
But if the axe isn't the murder weapon, then...
Then the presence of Warren's sweat
on the handle is irrelevant.
No.
I think the sweat being on there is the whole point.
Warren Bart is being framed.
He's innocent.
Again.
Your friend Warren is gaining followers.
Are we sure he's being framed?
The tool mark analysis was as conclusive as can be.
The axe Warren handled didn't kill Nate.
The sweat on the handle actually helped his case, too.
How?
The blood that we drew from Warren has high levels
of HGH and gonane.
Warren's taking steroids?
It's bulking season, I guess.
But neither chemical was present
in his sweat on the axe.
So, whoever left the axe for us knew
that Warren had touched it at some point in the past,
and they just figured, "Good enough."
There's a new one. "I-I couldn't have done it, Your Honor.
I'm taking illegal steroids now."
So if Warren's innocent, and the axe is out, we're nowhere.
We don't even know what kind of weapon was being used.
That's your domain. Get to it.
You got it, boss.
That's your domain. Get to it.
You got it, boss.
You two, the killer knows a lot about you,
Nate, Warren, and the Reynolds case.
You better get shopping online for followers.
You think it's someone who follows me and Warren?
That's a suspect pool of thousands of people.
Yup. You better get started.
The blood drops on the balcony
that we want to replicate were all smaller than one millimeter.
Whatever the killer was slicing and dicing with,
it was moving fast.
All right, hope you stretched, Beau.
Let's figure out what it was.
♪ ♪
RAJAN: Grief and pain.
Product placement. Grief and pain.
I mean, that is a proper social media sandwich.
Got to pay the bills.
I once shilled for cat food
in a video I made about the Menendez brothers.
Chris, you're allergic to cats.
Warren Bart has killed again, and now, the only question is,
will Chris Park help him get away with it... again?
Who the hell is this guy?
That's @SleuthVCF.
Kind of like the Lestrade to my Sherlock Holmes.
Oh. Sherlock would have a suspect by now, so, uh...
Sorry.
Mm-hmm.
Warren and Nate are still gaining followers.
For every suspect we eliminate,
ten more names pop up that we need to check out.
It's like troll whack-a-mole.
Well, human tragedy does bring the boys to the yard.
Take a look at this.
Wow. There's nothing
like a few hundred people sliding into your DMs.
With pitchforks in hand.
Forgive me, Chris.
I'm gonna have to be your mom for a second.
Are you out of your damn mind?
You cannot put yourself out there like this. It's dangerous.
My little corner of the Internet was never this extreme.
Well, now someone in your little corner is killing people.
You never know who is watching you,
or what they are capable of.
Now, the next Mark David Chapman could be lurking
in your damn comments.
Who?
Now I'm gonna talk to you like your boss.
You need to start carrying a service piece around the clock.
At home, too?
Mm-hmm.
Don't you always say a CSI's mind is their best weapon?
I do.
But someone threw your name into the mix.
So I'd say this case requires more tangible protection.
And I want you safe.
Keep your head up, mate.
I'm not sifting through this toxic cesspool alone.
WOMAN: And this is the crime scene from above...
RAJAN: Hey, that's illegal.
You can't film an active crime scene like that.
Check it out. Okay, I know I'm breaking the law
by shooting this, but...
Well, at least she's self-aware.
Don't forget to like, comment. Love ya.
Aah!
Nope. Uh-uh. Pay up, Beau.
Damn. Thought for sure it was a power tool.
Not the first time Bob Vila's let me down.
Now you know how I felt when the halberd failed.
And the poleax.
You guys find the murder weapon?
No. We are officially out of weapons and ideas.
Pretty much the only thing that we haven't tried is that, like,
razor-sharp boomerang from The Road Warrior.
I know you're joking, but...
you might be closer than you think.
This was filmed by the murder weapon.
Hey, Beau, don't drones have, like, safety features
that stop them from hitting buildings or... people?
Yeah, those are easy to override.
First thing I did when I bought one of these for my daughters.
Was it really for your kids, Beau?
Yeah.
They love watching me fly it.
Whoa. Whoa.
I got it.
Whoa. Whoa.
I got it.
And that, gentlemen, is how you make the perfect mess.
No footprints, no void in the blood.
Because there was no killer there. We-we got our answer.
Only one of them-- how, not who.
I guess we got to hope that the killer left a trace
of himself at the house when he planted the axe.
They'd never need to get that close.
The largest commercially-available drones
could carry a tool that size as payload.
Well, drones like that are standard tool of the trade
for some influencers.
Doesn't narrow it down much.
I think MurderHouse might be a good place to start looking.
MurderHouse?
PARK: That's what they're calling it.
Some of Nate's roommates
have rebranded.
Who would want that kind of a brand?
Bro, check out my first search warrant.
It's just like on TV.
Do you really need to be filming this?
You better believe it, lady. (laughs)
Just another day in MurderHouse.
It's nonstop over here, man...
This is harassment, okay?
I'm not talking to you guys without my lawyer.
Well, you don't need to talk at all.
We just need to see your drone.
I don't own a drone.
You and literally every one
of your housemates have posted drone footage.
Someone in this house has one.
Warren, if it's here, it'll only take us five minutes to find it.
Forget it. It won't even take that long.
Hey.
Two minutes and 45 seconds.
The propellers are damaged.
We got blood.
We got the murder weapon.
Actually...
What?
It's all rusted where the blade broke.
I don't think this thing's been air-worthy for a while.
Could you, uh...
hold that, please?
Nate had O positive blood, but this...
It's not his blood?
Wonder how long it's been here.
Four years and three months.
That test did not tell you that.
The woman Nate and Warren were accused of killing?
She had A positive blood.
That drone didn't kill Nate Taylor.
It killed Ana Reynolds.
They really did murder her.
And I helped them get away with it.
Look at the photos, Warren.
Look at them.
You can't, can you? I get it.
What you did to Ana was...
We found Ana Reynolds's dried blood on your drone.
Blood leaves DNA, and DNA leaves no doubt.
PARK: He's not going to talk. How about this?
Why don't you stop me when I get something wrong?
Around 11:00 a.m...
What is it you're hoping to...
Around 11:00 a.m.
on August 5, 2018,
you took your new quadcopter drone
out for a spin.
You saw Ana sunbathing
and decided to get a closer look.
Maybe you wanted to prank her.
I checked. The drone's safety features were disabled.
That allowed you to get way, way too close.
When you ran into Ana's yard,
she was bleeding out, dying.
But instead of calling 911, you panicked.
You didn't want her telling the cops what happened,
so you finished the job yourself
with Nate's camping axe.
Perhaps Mr. Taylor...
You ransacked Ana's house
to make it look like a robbery, you washed the axe
to destroy the evidence.
I want to know why you kept the damn drone.
I don't own a drone!
Warren.
PARK: No, that's right.
We found it in Nate's closet.
He's the one who kept it.
Well, that's telling.
It tells me
Well, that's telling.
It tells me
that by the time Nate found out what happened,
he was already charged with murder.
Your fates were tied together.
Maybe he kept it for leverage.
Is that what this was all about, Warren?
CSIs only found your footprints in Ana's yard, Warren.
Was Nate even there?
Or did you just let your best friend stand trial
for murder with you to save yourself?
Was he threatening to come forward
about what really happened?
Is that why you killed him?
Even if this story was true--
which, for the record, it is not--
my client can't be charged.
He's protected by double jeopardy.
PARK: Your client
killed Ana Reynolds.
Mr. Bart was acquitted of those charges,
so the story you cooked up is just that: a story.
Wrong. It's what happened. We have new evidence.
Not nearly enough evidence
to overpower Mr. Bart's constitutional protections.
My client can never be charged again.
And as for Nate Taylor's murder,
Mr. Bart's alibi remains unchanged.
He was asleep when Nate was killed.
She's right.
You're free to go, Mr. Bart.
I helped a man get away with murder.
FOLSOM: You knew there was something wrong
with the prosecution's case, and you said so.
They hadn't figured out the MO.
Look, Warren's acquittal's on the D.A., not you.
Not even this lab.
We can't change the past, Chris.
We have to focus on Nate now.
I am.
And I think Warren did it again.
He could have used a new drone to fake being framed.
Think about it: what better way
to get away with murder for a second time?
I can barely track that logic.
I sincerely doubt that Warren could.
He just doesn't have enough going on upstairs.
Okay, I want to talk about upstairs, actually.
The balcony. So,
the killer never set foot up there, which means
that the killer wrote on Nate's eyelid before he went outside.
Another guest at the party.
RAJAN: That only narrows it down a little.
It was practically an open house that night.
Anyone could've gone in and out.
True, but what is
the one thing that everyone at that party was doing?
Filming.
Constantly.
Maybe one of them caught the killer on camera.
I'll scrub all the housemate's accounts,
try to find anyone who was hanging around Nate.
Maybe catch Warren in a lie.
Okay, so, I think it's time
that you and me learn a little more about invisible ink.
Hey.
Thought you'd want to know.
Hmm.
LVPD finished its investigation into Chris's social media.
And?
He didn't break any rules.
At least not since joining the lab.
No sanctions recommended, no suspension.
Good. I'd love to go a full year without a scandal in my lab.
But there is something you should see.
Try searching #ChrisFails.
Okay.
Who's this guy?
Keep scrolling.
"@ChrisSolves, if we find you,
you'll wish you'd have ended it."
Okay, that's basically a death threat.
And that's just the public posts.
I mean, his DMs are worse.
I told him that he should be carrying.
What do you think about putting a uni on him?
At least till this blows over?
Yeah, yeah.
Yeah.
You know, he does seem a little... idealistic.
Not always conscious of taking precautions in the field.
Uh-huh.
Sorry. I'm just...
How did your doctor's appointment go?
It was a routine post-concussion checkup.
You were admitted to a hospital.
For an overnight sleep test. I'm fine.
I'm fine. (laughs)
Okay.
Good.
Lot of people been asking,
"Vincent, how did Warren Bart get away with murder again?"
Well, let's start from the beginning.
Hello, Unknown Blonde Guest Number 14.
You've won an all-expense-paid trip
to my spreadsheet of suspects.
I mean, there weren't this many people at my wedding.
It's gonna take days for us to log everybody
Nate's interacted with.
WARREN: We out of here-- free Warren!
Peace, love,
truth prevails, baby!
Truth prevails! Let's go!
Excuse me. If you're gonna self-flagellate,
could you find someplace private?
We got a lot of party to go through,
and I can't give it the Zapruder treatment solo.
Can you tell me why anybody would want to do this?
Be a... be an influencer?
Yeah, I can.
Having thousands of people tell you
that what you're doing is cool feels... awesome.
A little too awesome. It's addicting, really.
I've been there.
I mean, kind of.
Getting praise for the wrong reasons.
That's the reason I left Dow.
I started to care more about the attaboys than the...
the work itself, the...
FOLSOM: All right, so,
invisible ink was a bust.
It just came from a generic, store-bought pen.
(clicks tongue) Nothing traceable.
But I did solve one minor mystery.
Hmm. Oh.
Did Sonya take that for her collection? I know she was
jazzed about the burst blood vessels.
No, I-I took that, thank you very much.
And look-- those aren't burst blood vessels
that caused the trauma after all.
See that? That's mucus under the invisible ink.
Nate had conjunctivitis.
The victim had pink eye?
Probably not the worst infection bouncing around that house.
Boy, he's a tough crowd today. Usually...
Guys, guys.
I think I found the drone.
In the parking lot earlier, Beau almost crashed
after slicing the dummy's neck, right?
Excuse me. Landed it just fine.
Right, right, but maybe the killer didn't.
This video was posted within minutes
of Nate's estimated time of death.
So where did it land?
Yeah, the drone had to have landed right around here.
Damn.
Well, it's already been two days.
We're not that lucky.
But you see that?
What?
Oh, man.
Oh, this bush is attacking me.
Gotcha.
What is that?
I think it's a piece of a wet wipe?
Looks like a little-little critter kind of got to it.
Shredded it up pretty good.
Yeah, looks like a rat tore it up for its nest.
Oh. Oh.
That is definitely blood.
So the killer cleaned Nate's blood
off the drone after the murder.
A rodent saved a piece of evidence for us.
If the killer wasn't wearing gloves, we could have DNA.
Stuart Little might've just solved your case, Chris.

FOLSOM: Still inconclusive?
ROBY: Looks like any touch DNA
on your sample is beyond hope.
But you still have the partial alleles.
Can't you reconstruct the DNA with the PCR thing that you do?
You know, how they fill in the gaps
like they do in Jurassic Park?
So, first of all, that's not a thing.
And secondly, no, because your sample--
it took a bath in Clorox.
Oh, man.
Mm.
Oh, man.
Mm.
If I had thought about how much bleach is baked
into these wipes, I would've spared myself the pain.
You got to get some antibacterial on that
'cause it could still get infected.
Whoa, hold on. Scratches.
No, it's fine.
No.
No, it's fine.
No.
Scratches.
For those viewers coming over from @ChrisSolves' channel,
welcome, my friends, to the right side of history.
Hold still.
No. It hurts.
Isn't swabbing, like, CSI 101, Chris?
Hey, can you be careful with that stuff, please?
That's my livelihood.
CHAVEZ: We got a warrant, bud.
That's my livelihood.
CHAVEZ: We got a warrant, bud.
This is a big-time setup.
Yo, how many followers you got there, @SleuthVCF?
(chuckles) You can call me Vincent.
And, gosh,
I don't know.
How about those scratches?
Where'd you get them?
I went hiking at Lost Creek last week.
PARK: Lost Creek?
That's a paved trail.
I like to go off
the beaten path, Chris.
Got a little too ambitious.
I know you follow me online.
I follow you, too.
You reviewed
a heavy-duty quadcopter drone six months ago.
I sold it a week later.
It was just too big, hard to fly.
It didn't, uh...
elevate my content. (chuckles)
It's not here.
All right, well,
if you guys are done, I have
a live stream in ten minutes, thank you very much.
Take off your glasses.
No. Why?
You can do it, or I can do it for you.
Our warrant covers your physical person.
Okay.
Thank you, Vincent.
I'm gonna get to practice my swabbing.
Right in your eye.

PARK: Got some bad news for you.
The kind of pinkeye you have?
Antibiotics won't help.
It's gonna linger for a while.
Okay.
I guess nobody should borrow my mascara.
What are we talking about?
We're talking about the adenovirus
that's causing your conjunctivitis.
And the fact that it's...
100% identical
to the strain we found in Nate Taylor's eye.
You got it when you scribbled
my internet handle on Nate's face.
FOLSOM: You steered Nate out onto that balcony.
And then you revved up that drone that you claim you sold.
And you slit his throat.
FOLSOM: You can deny it, but, uh,
going viral here?
It's gonna put you behind bars.
PARK: See, Vincent, it's the little things.
Like, microscopic.
But you already know that, you're a super sleuth.
I was right.
The whole time.
About everything.
I always said that Warren and Nate were guilty.
And you said I no idea what I was talking about.
That my grasp of evidentiary
procedure was weak.
You remember that?
Do you know what that did to my credibility?
Do you even realize what that video cost me?
I lost 20% of my followers overnight.
You only had 8,000 followers at your height, Vincent.
You really think that...
a couple thousand people clicking unsubscribe
justifies murder?
Shut up, boomer.
It's not just the followers.
'Cause you rode that momentum
all the way here.
All the way to my dream job.
If you wanted to be a CSI, you could've just applied.
I did. And I got rejected twice.
So I used it as fuel.
For what?
To get the truth out there.
For what?
To get the truth out there.
About Warren Bart... and Nate Taylor.
So I did what you people couldn't.
I figured out how Ana Reynolds was killed.
All right, let's go.
Now everybody knows, Chris.
All right, let's go.
Now everybody knows, Chris.
Everybody knows that you're a fraud.
CHAVEZ: Hands behind your back.
You don't even deserve to wear a lab coat.
I found you, didn't I?
You helped a murderer walk, Chris.
I just punished one.
Let's go.
ROBY: I have some good news.
LVPD has cleared you.
You are off the hook with them.
But you are not off the hook with me.
These videos that you post.
Just putting yourself out there, it's...
After this, I promise I get it.
And again...
I'll never post about an ongoing case.
These days...
every time you leave this office,
you are at risk.
We have to be smart.
And we have to protect ourselves.
From now on...
I'll stick to Instagram.
Are you kidding me? Instagram...
I'm kidding. Kidding, boss.
Do not make yourself a target.
PARK: I need to set the record straight.
I was wrong about the Ana Reynolds case.
My theory that Warren Bart
didn't kill Ana with an axe missed the point.
This was the murder weapon.
By now you've all heard we found one
just like it in Warren's house.
I don't get to say that Warren Bart is a murderer.
But I can say
that he shouldn't benefit from the deaths
of Ana Reynolds and Nate Taylor.
So don't like.
Don't subscribe. Unfollow Warren.
Don't give people like that any more eyeballs.
Me?
I'm signing off.
For good.
