Hawaii Five-0

Sir?

Allow me.

Thank you, miss.

You're welcome, sir.

_

This is the Neptune Four research team,

conducting dive four of our salvage mission.

Approaching the west side of crash site.

I'm gonna get in close, see if I can identify some spots

for the lift bags.

What is that?

Zoom in.

It looks like a diver.

Oh, my God.

Uh...

I'm sorry, Ms... .?

Liu.

Sergeant Liu, actually.

Military Police Corps.

I was there when you were arrested

on conspiracy to commit murder.

See?

- You remember. - I didn't realize

we had a breakfast on the books.

Otherwise, I would have asked for a rain check.

I'm sorry, this is so spontaneous, but...

I wanted to share some news with you.

Someone planted a bomb at Commander McGarrett's house.

- Well, that's terrible. - Mmm.

Is he okay?

McGarrett? Oh, he's fine.

I mean, it helps that whoever did it was, uh...

What is that word?

Incompetent.

See, McGarrett has this dog.

I mean, he's no ordinary mutt.

He used to hunt IEDs for the Marines.

So he just sniffed that bomb out with no problems.

Well, that's a relief.

Do you have any suspects?

Ah. That's funny.

Because, once again, I have a feeling that y-you don't have

any evidence to back up that slanderous allegation.

Otherwise, I wouldn't be sitting here,

enjoying this delicious breakfast with you.

You know what?

You're right.

This is delicious.

Well...

Sergeant Liu, thank you for coming all this way

to update me in person.

Nice as this chat has been, I can't help but think

you'd be better off spending your time looking for the person

who's actually responsible for planting that bomb.

Mmm. Can I share something with you?

I'm one of those, uh, clingy types.

- Hmm. - And once I'm interested in somebody,

I can't let go.

So, basically, what I'm telling you is,

you will be seeing a lot more of me.

And Commander McGarrett.

And the rest of the Five-O team, for that matter.

So we are gonna be all up in your business 24/7.

- Lucky me. - Yeah.

Well, when that luck runs out,

we're gonna be there to take you down.

One for the road?

We'll catch you later.

- Breakfast is served. - Hey. Thanks.

Good job in there.

Sounds like you really got under his skin.

- Yeah. It's a talent I have. - Well...

This is an excellent croissant.

Oh, you should have seen his face when I dug

into his bread basket.

Totally triggered him.

Yeah, it did.

He's making a call.

Hey. I got a job for you.

Yeah, usual spot. An hour.

All right, let's see who Cullen's setting up a meet with.

Look at that. It's a burner.

Well, that's a surprise.

So, what's next?

It's a good thing you got the day off work.

This stakeout just officially turned into a tail.

Do you think this plan of McGarrett's is gonna work?

Hell, I don't know.

I know one thing: you ever try to talk Steve McGarrett

out of a plan... any plan, no matter how damn crazy it is...

Is a losing proposition.

Yes, true,

but, you know, it's like that saying about pulling a lion

by the tail.

Oh, yeah. Yeah, that sound like something you just made up.

All right. Well, you understand what I'm saying.

Annoying the enemy

in the hopes that he might do something irrational,

that's-that's a bold move,

especially when that irrational thing might be eating you.

Or, just setting aside the lion analogy for one moment,

blowing up your house again.

Are-are you... are you okay?

'Cause you seem a little...

And please don't take this the wrong way, but cranky.

Oh, no, that's the right way.

So, is the apartment search not going well?

Hell no.

Matter of fact, I'm starting to

get the idea that I got a better chance

of getting a selfie with Bigfoot

than getting an apartment in our price range.

Victim's name is Jay Kahale, 38.

According to records, he was a demo diver in the Navy

until five years ago when he switched to private sector work.

He was found down 180 feet underwater

inside the wrecked fuselage of a plane.

Oh, you mean that wreck

that they, uh, found near, uh, Pupukea?

I saw that on the news. That?

Yeah, well, that's probably where Kahale

heard about the wreck, too.

Because, according to the diving company,

he wasn't a member of their salvage team.

They're thinking he just decided to take a sneak peak before

- it was brought up to the surface. - Well, based on the hole

in his head, I'm guessing he didn't just run out of oxygen.

Correct.

C.O.D. was a single .357 Magnum round

through the back of the head.

Hang on a second. I realize the .357 is a powerful iron,

but last I checked, you can't fire one underwater.

No. The official murder weapon was a power-head.

- A what? - Oh, a bang stick.

It's a specialized firearm

used by divers

to fend off sharks.

And because the density of water is approximately 800 times

that of air at sea level, the device needs to be fired

while in contact with the target.

Which means our killer had to be close enough

to press it into the back of our vic's head.

So, looks like our killer was very, very sneaky

and was able to come up behind him undetected.

Right.

The two of them were diving this wreck together.

The killer decides to stick it to Kahale when he's not looking,

left him there for fish food.

Mm-hmm, well, that explains the how.

- Doesn't explain the why. - Yeah.

What the hell could've been on this plane

worth killing for?

A decades-long mystery

may soon be solved.

Today, a research team has announced the discovery

of Flight 912, the commercial plane

that crashed over the Pacific in 1983.

It'll be several days before the plane

is dredged up and returned to Hawaii.

In the meantime,

federal investigators are awaiting

the recovery of the plane's black box,

hoping it will finally explain what caused Flight 912 to crash

more than 36 years ago.

This report aired the day of the discovery,

so the research team had already ordered

the deep-dive recovery equipment from the mainland,

and it's due to arrive later today.

Which means three days passed from the announcement

of the plane being discovered

to our vic's body being found early this morning.

So, Kahale had a 72-hour window to dive down to that plane

before it was going to be dredged up.

What the hell was he doing down there?

I don't know, but wreck diving

is pretty risky, especially in confined spaces like that.

Which is why it's almost always done in teams.

Well, that supports our theory that Kahale's killer

was his dive partner.

Check this out. Our vic's phone was turned on

a couple hours after T.O.D.

It pinged off a tower in Haleiwa.

HPD canvassed the area and found

a burnt-out boat registered to our Vic.

CSU is processing it now.

So the killer uses

the victim's boat to get back to shore

and then torches it to destroy any incriminating evidence?

Certainly confirms that they were working together.

Right. But why power on Kahale's phone after killing him?

Okay.

So, we know this was at least a two-man job.

We also know that our killer's an experienced diver,

so let's look into the Vic.

His phone records, employment records, the whole shebang.

Let's see if we can figure out who he was diving with.

- All right, you got it. - In the meantime,

you, with me.

We need to learn more about this plane crash.

I guess it is true what they say.
