New York: Postmortem examination of the body of Mary T. Mara,61, a veteran television actress who was found dead in the St. Lawrence River Sunday, revealed that she passed away by ‘asphyxiation’ due to drowning, usmagazine.com reported while quoting NYSP Troop D Public Information Officer Jack Keller on Wednesday.

“The Jefferson County Medical Examiner’s Office performed a post-mortem examination on the decedent and determined that the decedent’s manner of death was an accident, due to asphyxiation, due to warm water drowning,” it said.

Mara was found by first responders in Cape Vincent, New York, around 8 a.m. on Sunday, June 26. Per a press release from the New York State police, emergency personnel responded to a call about a possible drowning in the St. Lawrence River, which borders Canada. The actress was in town visiting her sister Martha Mara.

“The victim’s body showed no signs of foul play and was transported to the Jefferson County Medical Examiner’s Office,” law enforcement officials said in their statement.

The following day, the Ray Donovan alum’s rep, Craig Dorfman, confirmed her untimely passing in a statement to Us Weekly.

In a statement, her manager, Craig Dorfman, described her as “electric, funny, and a true individual” who was well-loved, as well as a tremendous actress.

Her earliest acting credit goes back to the 1989 movie “The Preppie Murder.” The New York native worked regularly ever since, in a combination of repeat characters in some shows and appearances in others.

The actress worked off-Broadway early on in her 32-year career. She made her feature film debut in 1992, starring in Love Potion No. 9 alongside Sandra Bullock and Tate Donovan. Mara played Billy Crystal’s daughter in the film Mr. Saturday Night that same year. Crystal, who’s starring in the Broadway adaptation, said he will be dedicating Tuesday night’s performance to his former co-star.
