Bobby, welcome back to the show, although it's on an awful story. What would divers look for in the ocean?

There are strong currents there. That's right, Elizabeth. And normally you won't put divers in the

water unless you have a finite area to search. So unless you've narrowed it down to an area where you

think this person may be. And as you've seen some of these helicopter shots, the water there is crystal clear.

You can actually search from the air with those drones you mentioned and with those helicopters

you saw on your shot there, how crystal clear that water is.

So if there's a body down, you could probably see it.

The thing you want to know is where it could have drifted to.

You want to know the prevailing winds, the prevailing currents in that area, and so where that body might have drifted,

because over a number of days, that body's going to move. You're not in a lake, you're not in a river.

You know, the body's going to move, and so you want to know which way it's moving, and then you want to concentrate your searches in that direction. The waters in this area can get rough, even though it looks pristine and beautiful in this video

and these pictures that we're showing you. Four tourists were just swept away and drowned

two months ago right around this area. It was worth saying, though, authorities recovered

their bodies soon afterwards. They have not found hers.

That's right. That's what strange about this is that her body has not surfaced yet and drifted

either to the shore, either up or down that beach somewhere. So that that is unusual to have to go this

long. And like you said, there's a very recent example of just several weeks ago of that happening

and the bodies being located. So, you know, you're doing two parallel investigations. You're

doing one on the drowning and one on the possible foul play. And both are kind of moving in the

same direction. The interviews with that young man from Iowa are crucial, not only on the foul play

side, but on the search side, I want to know,

you know, what was she wearing, you know, where was she in the water exactly, how far out
