Family of NYC designer Martha Nolan-O’Slatarra searching for ‘more details’ into who she was with night of Montauk death: ‘Far from typical’

The family of Martha Nolan-O’Slatarra wants to know who crossed paths with the chic designer the night she was found dead on a boat in Montauk as police continue their “deep dive” investigation into the tragic case, according to their lawyer.

Attorney Arthur Aidala pushed back against speculation that Nolan-O’Slatarra, 33, died of an overdose and told The Post Wednesday that the Irish-born beauty’s family “did not know her to be someone who used drugs.”

“They want more details,” Aidala said. “The circumstances surrounding this are far from typical.”

“They would like to know anyone who was with Martha that evening,” Aidala continued. “Earlier that evening, at the time of the actual incident, we know one person who was there. Was anyone else around?”

The attorney revealed at a press conference Wednesday that “people are still being questioned” by homicide detectives on the East End.

“The family has had a sit down with the Suffolk County homicide detectives. They are doing a deep, deep dive, a deep investigation. People are still being questioned,” Aidala told reporters Wednesday.

Aidala told The Post the family “absolutely” fears that their beloved daughter could have been unknowingly slipped drugs that resulted in her death.

“If there was any kind of drug and drug use, they want to know. Who’s doing the drugs?”

The attorney said the family is currently working with law enforcement, and also with retired members of law enforcement to ensure the investigation is being handled properly.

Nolan-O’Slatarra was found unresponsive on a boat named “The Ripple” which was docked at the ritzy Montauk Yacht Club, on Aug. 5, according to the Suffolk County Police Department.

That boat belonged to Chris Durnan, 60, who is well-known locally and who owns another boat moored at the same dock, the “Hell In A Bucket.”

Durnan owns and operates an insurance company called the Durnan Group located in Rockville Center.

Durnan has not responded to The Post’s numerous requests for comment.
