NYC fashion designer found dead on Montauk yacht was cold and bloodied

Fashion designer Martha Nolan-O'Slatarra, 33, was found unresponsive aboard a yacht at the Montauk Yacht Club around midnight on August 5, 2025. According to newly revealed medical records obtained by the New York Post, EMTs discovered her cold to the touch with dried blood around her mouth, chest and head, and additional blood on the floor near her body.

Good Samaritans and first responders attempted CPR at the scene, but she was pronounced dead at the scene.

The Montauk Fire Department patient care report documented that Nolan-O'Slatarra's nail beds were purple, with slight purpling around her lips. Despite the visible blood, EMTs noted there was no active bleeding or obvious source of trauma, though one responder believed some of the blood may have come from the back of her head.

The report also mentions an unidentified man who told EMTs he had been present at the time of the discovery.
