Hawaii Five-0

Previously on Hawaii Five-O...

Michelle Shioma's 20 million.

You're gonna get it and hand it over.

Jessie, this is Mr. Kimura.

He's an old friend of my father's.

What the hell is this place?

It's sort of an unofficial bank for the Yakuza.

I need to make a withdrawal.

We just had a body wash up on Kaalawai Beach.

It's Noriko, Adam's sister.

Adam just saved

my brother's life. I'm supposed to repay him by turning him in?

You're a cop, and you took an oath.

If Adam killed his sister, you need to do the right thing.

Why'd you put that at my house?

I didn't, Adam.

I found it there when you were away.

You're telling me it's sheer coincidence

that a gun I've never seen before

turns up in my drawer right after you've been there?

Let's go, guys. And then three hours later,

HPD shows up with a search warrant?

But if you didn't plant the gun

and you didn't tip the cops, who the hell did?

Mr. Kimura.

We called you here to relieve you of your duties.

You will no longer serve as our banker.

Masuda-San, may I ask why?

Noriko Noshimuri.

You had her killed

and attempted to frame Adam Noshimuri, did you not?

You are meant to be a ghost.

To move among the shadows.

Instead these rash actions have drawn

unwelcome attention to us all.

M-Masuda-San...

I-I was protecting your interests.

Adam Noshimuri was withdrawing money

that was paying his father's debt to you.

Some things are worth more than money.

We are sometimes allies,

sometimes rivals.

To function as our banker,

your neutrality and honor must be unquestioned.

When you act

against any one of us, you betray us all.

Now, in recognition

of your years of service, we offer a choice.

Yakuza justice...

...or Five-O justice.

Hello, Mr. Kimura.

It's 1:35 a.m. I'm here at Wai'alae Beach Community Park,

where we've had reports of drug activity.

Looks like we got something here.

I now have video evidence of a drug transaction.

I'm moving in.

Yo, are you filming me?

On your knees. I'm making a citizen's arrest.

Turn that off.

Okay, you saw what just happened.

He pulled a gun on me.

I'm gonna need to wait here for the police to file a report

and turn over the firearm.

Hopefully they can ID our perp

and track him down.

In the meantime...

...let's take a look and see what we got here.

Looks like about a dozen bags of methamphetamine.

Not a bad night's work.

The good people of Hawaii can sleep safer tonight

knowing that these drugs are...

Please, no. No!

Victim is Gene Wahale.

He's a self-proclaimed vigilante.

Calls himself the Night Sentinel.

He liked to go around the island

making videos of himself confronting criminals.

Please, no. No!

Well, shooter's wearing a mask.

Camera didn't get the vehicle's plates.

All right, let's put out a BOLO, Duke,

for a gray sedan with some front end damage.

All right, I'll take a shot.

Uh, say our dealer had somebody

posted up like a lookout. He sees the altercation,

gets in his car, runs the guy over.

One problem with that.

- The dealer's backpack is still here. - Let me see.

Over there.

There's over five grand

in cash and drugs still in it.

Sounds like this isn't connected to the murder.

Looks to me like maybe somebody trailed our vic here.

Waited, saw this confrontation,

saw it as the perfect opportunity.

Took him out.

As tragic as this is, it's hardly surprising.

Yeah. - Guys like this try to be heroes.

They jump into situations they're not trained for.

They put themselves and the public at risk.

They should just leave law enforcement to professionals.

I agree. You know, you see

a couple Batman movies, doesn't make you a superhero.

Right? Let alone a cop.

Right, right.

Thanks, Duke.

Jer.

What are you doing here?

I met him once... when he was on patrol.

I got a picture. You want to see?

Sure.

People say they want to make a difference in their communities,

but Night Sentinel actually did something.

Guy was fearless.

Yeah, I mean, you know, you get involved

in the kind of stuff he's involved with,

eventually you're gonna make some enemies, right?

Yeah, but the people that matter,

the folks in these neighborhoods,

they loved him.

Made 'em feel safe.

This park used to be a no-go zone.

Now it's, I don't know,

maybe the odd dealer.

Night Sentinel was winning the war.

Well, speaking of that, uh, Jerry,

how long was this war going on?

Come on, give me your wallet.

I don't have anything, I swear.

I'm making a citizen's arrest.

It's okay. It's gonna be okay.

These videos go back to 2015,

when Night Sentinel first came on the scene.

There's over a hundred of them,

and those are just the ones he deemed good enough to post.

According to HPD records,

Gene Wahale made 37 citizen's arrests.

Everything from vandalism to armed robbery.

This guy was a serious vigilante.

His bread and butter seemed to be the drug trade.

That accounts for two-thirds of his busts.

That's the other thing-- you take out enough dealers,

you're gonna seriously impact somebody's distribution network.

Now, that's got to have consequences.

Mm-hmm, and the comments on these videos

seem to be making the same point.

Check this out.

I-I don't know what that means. Can you help me, millennials?

Okay, well, gangs now use emoji code to make threats.

So, scissors means "I'm gonna cut you."

And then look at this one.

Skull, right arrow,

fire emoji?

"Die in a fire."

And those are some of the nicer ones.

Okay, clearly half the island's criminals wanted this guy dead.

Why'd you post those threatening comments?

Sorry, guys,

you can keep asking, it's not gonna change my answer.

Never heard of no Gene...

Wahale. Gene Wahale.

Or Night Sentinel, as he liked to call himself

when he was out making citizen's arrests of local drug dealers.

Like your brother.

He's the guy who, uh, put him away for ten years.

Any bells going off now?

Sorry, still no idea what you're talking about.

Yeah, okay, Niko, how about this?

I'm gonna give you a little tip, okay, for your life.

If you ever manage to spend any substantial time

outside of a prison, and you want to kill somebody,

don't tell them, don't write it down,

"I want to kill you,"

i-in the comments section of their page. Okay?

And remember,

two Ls in "kill."

Okay. Okay.

Am I glad the freak's dead? Sure.

And, yes, I-I love my brother.

But I'm not interested in becoming his cellmate.

You expect us to believe

that, uh, all that talk was just, what, idle threats?

Is that it?

Like I told the cops,

last night I was at one of the island's

finest gentleman's clubs till around 3:00 a.m.

Dropped two Gs on my credit card.

You can check that if you want.

Hmm, maybe I'm not as dumb as I look, huh?

Yeah, 'cause

nothing says genius like dropping two grand

at a strip club.

Doofus.

So, Niko's alibi at the club checked out.

- He's not our guy. - Well, of course not.

Neither are the other 16 guys we've been looking into,

and they were the most promising ones we had.

We got a bunch more names on that list.
