A vacation nightmare in the Bahamas. New video showing a tourist ferry boat on its side and sinking, taking on water by the second after being battered by rough seas. Our boat is sinking. Kelly Shishoal, capturing the frightening play-by-play on her phone. From her view on the boat's upper deck, she watched the ferry slow descent into what had been beautiful blue waters. I'm on the top floor of a ferry. Frightened passengers seen huddling together, confused and terrified as the boat slipped farther underwater.

One of the crew members that was downstairs ran upstairs and was crying, freaking out, absolutely balling, grabbing a life jacket. And then that's when everybody's like, Oh, this is real. Something's happening.

Authorities say the double decker catamaran was taking close to 100 tourists to Blue Lagoon Island, Tuesday, just a few miles north of the Bahamian capital of Nassau. The first distress call coming around 11:00 a.

M. We were waiting for the staff to tell us what to do, which they never did because they were too busy crying and freaking out.

New video from another passenger, Sarah Grady, shared first a top story showing first responders on a nearby boat trying to render aid. Her mother injured as the boat sank. Some passengers didn't wait, jumping into the water until rescue boats could arrive. Authorities say a 74-year-old Colorado woman was pulled from the water, unresponsive, and later, pronounced dead. In a statement, Blue Lagoon Island saying in part, the incident occurred as the boat was approaching and near to the island, adding passengers and five staff members were located and brought to the island, and two passengers were taken to the hospital for additional care. All on board are accounted for. Tonight, authorities investigating the circumstances behind the fatal incident that turned an island getaway into a fight for survival.

Morgan Chesky joins us now, live from Dallas. Morgan, pretty scary video there. The strange thing is that it was a completely clear day. The water looks a little choppy, but you don't see a lot of white caps. My question is, do we know what happened? What went wrong?

Yeah, Tom, that is still being investigated tonight. In fact, other passengers we heard from took note of those very same conditions acknowledging the blue sky and sunshine, but saying that during their trip from one island to the other, the seas were exceptionally choppy. Now, we did reach out to that tour boat company. Tonight they have not responded to any comment or making any statement at this point in time. And the police say this remains very much an active investigation.

Tom. All right, Morgan Chesky tonight on Top Story. Morgan, great to see you again.
