This is the Interrogation Tapes, a special limited run series produced by ABC News Studios in partnership with 2020.

I'm Deborah Roberts, Co-anchor of 2020.

We've arrived at episode 5, Mystery on the Hudson.

When a man dies in a kayaking accident,

was it an accidental drowning or something more sinister.

Take a listen. I was sitting in the barracks.

I was sitting in the barracks, I was working.

I was a scientist, police Montgomery barracks believe it was a 3 to 11 shift

PM and we monitor all the fire rescue calls that come out.

I heard a call come over for a car car.

I heard a call come over for a missing kayaker.

The activity of these one wall in that club.

And I went out to the call just to see if I can get a hand

with the search efforts.

And they said that there was two kayakers, a female in a male, and the male had gone missing

after he had tipped over in his kayak. The female was transported to the local hospital in the area

The female was transported to the local hospital in the area because she had herself fallen into the Hudson River.

All right, so we'll talk about what we discussed this fair.

Let me just, I obviously say to all Jerry,

make you your rights with the knife.

You give the right to each sound.

Anything you say
