A Midnight Call and Desperate Attempts to Save Martha Nolan-O’Slatarra

The fateful night began like many in the Hamptons’ summer social scene—glamorous and carefree—but ended in horror. Around midnight on August 5, 2025, a 911 call was placed from the Montauk Yacht Club, reporting an unconscious woman aboard the 54-foot SeaRay yacht named “Ripple.” The caller, identified in reports as a man ,possibly her boyfriend or an associate alerted authorities to the emergency. Witnesses described hearing screams echoing across the docks, adding an eerie layer to the scene.

Good Samaritans, including nearby boaters and club members, rushed to perform CPR on Martha Nolan-O’Slatarra until paramedics arrived. Despite their efforts, she was pronounced dead at the scene. The yacht, docked at the ritzy club where rooms can cost over $1,200 per night, was immediately cordoned off by East Hampton Town Police. The Montauk Yacht Club, a haven for celebrities and influencers like Alix Earle, issued a statement emphasizing cooperation with law enforcement and commitment to guest safety.

Initial reports painted a picture of confusion and distress. One eyewitness recounted seeing a man, described as naked and frantic, shouting, “That’s my girlfriend!” as he sought help. The boat’s owner, a man in his 60s, was reportedly alone with her when authorities arrived. Nolan-O’Slatarra had texted her boyfriend earlier that evening, mentioning she would “Uber home” after what she called a business outing.

This detail has fueled speculation about the nature of her presence on the vessel—was it a professional meeting gone awry or a casual Hamptons party?

The Investigation: No Foul Play, But Questions Persist

Suffolk County Police Department’s homicide detectives quickly took over the case, a standard procedure for unexplained deaths. An autopsy conducted shortly after revealed no evidence of violence, easing fears of murder but leaving the cause “inconclusive” pending further tests, including toxicology.

Renowned forensic pathologist Dr. Michael Baden suggested results could come within a week, but as of August 13, 2025, official confirmation remains elusive.

Sources close to the investigation, cited in the New York Post, point to a suspected accidental drug overdose as the leading theory.

This aligns with broader concerns about Montauk’s evolving party scene, where rising wealth and celebrity influx have brought scrutiny over substance use. Fox News reported that the incident has “sparked scrutiny of Montauk’s party scene,” highlighting past tragedies in the area.

Despite ruling out violence, the probe continues. Police have interviewed witnesses, reviewed security footage from the yacht club, and examined Nolan-O’Slatarra’s communications. Her boyfriend, not on board that night, has cooperated, according to reports. The Irish Department of Foreign Affairs is providing consular assistance to her family, who are grappling with the loss amid a lack of clear answers.

Family members, including her sister Jacqui, have expressed frustration over limited information, with one relative stating, “We weren’t told anything about the circumstances.”
