Cause of Irish Designer’s Death on Hamptons Yacht Remains Undetermined

Investigators found no evidence of violence pending detailed toxicology results

Overview

  • Martha Nolan-O’Slatarra, 33, was found unconscious aboard the yacht Ripple at Montauk Yacht Club on August 5 and was pronounced dead at the scene.
  • The Suffolk County Medical Examiner’s autopsy revealed no external trauma and the final cause of death awaits toxicology and histology analyses expected in coming months.
  • Unnamed sources reported she had met yacht owner Christopher Durnan that night and photographs allegedly show white powder aboard the vessel, but authorities have not verified those claims.
  • Court records show Nolan-O’Slatarra finalized an uncontested divorce in April and had recently launched her East x East resort-wear label pop-up at Gurney’s Montauk Spa.
  • Montauk Yacht Club officials say they are cooperating with law enforcement and local reports note the Ripple was removed from its slip shortly after the incident.
