MONTAUK, N.Y. — A single line of newly released dispatch audio shows just how little distance New York authorities have covered in nearly two weeks since a luxury summer getaway turned into a mysterious tragedy when 33-year-old swimwear entrepreneur Martha Nolan-O’Slatarra was found dead aboard a docked yacht at the exclusive Montauk Yacht Club.

Suffolk County Police detectives launched a homicide investigation shortly after Nolan was discovered unresponsive on a vessel named the Ripple just after midnight on Aug. 5.

In a police radio recording provided by Broadcastify, a dispatcher can be heard announcing the situation in blunt terms.

“Adult female, unconscious, not breathing at the Montauk Yacht Club,” he says.

Despite frantic CPR attempts by good Samaritans and first responders, she was pronounced dead on the yacht.

Nolan, an Ireland-born businesswoman who ran a popular Manhattan-based summerwear label, had recently celebrated a successful pop-up event in the Hamptons and was days away from flying home to Ireland to visit family.

While an initial autopsy found no signs of trauma, investigators are awaiting toxicology results to determine her cause of death. Here is a timeline of what we know so far:

Shortly after midnight: East Hampton Town police officers responded to a 911 call from a man who discovered a woman unresponsive aboard a Sea Ray 540 Sundancer docked at the Montauk Yacht Club. Good Samaritans attempted CPR before first responders arrived, but she was pronounced dead at the scene.

“Adult female, unconscious, not breathing at the Montauk Yacht Club,” a dispatcher said in a police radio recording provided by Broadcastify.
