Aug. 5 (UPI) -- Police are investigating after finding the body of a woman from Manhattan on a boat docked in a high-end marina in Long Island.

East Hampton Town Police discovered the body early Monday morning at the Montauk Yacht Club after responding to a call reporting a woman unconscious on a boat, according to a police press release.

Bystanders attempted to revive the woman, identified as 33-year-old Martha Nolan-O'Slatarra, using CPR but she was pronounced dead on the boat by first responders. Police were unable to determine Nolan-O'Slatarra's cause of death, and the Suffolk County Medical Examiner's Office will conduct an autopsy.

Meanwhile, the Suffolk County Police Homicide Squad detectives continue their investigation into her death, according to the press release.

A spokesperson for the Montauk Yacht Club declined to provide further details to Fox News Digital, saying they were saddened by the incident.
