Suffolk County Police Homicide Squad detectives and the East Hampton Town police are looking into the circumstances surrounding Ninive Petrocelli's death, the county police said in a statement.
The woman, whom they reported was 40 and lived in New York City, was reported missing from a 45-foot pleasure craft "In the Clutch" just after midnight on Sunday. She and her husband, John Petrocelli, 54, were boating in Block Island Sound off Montauk Point when he noticed she was not on the boat, police said.
"He notified the United States Coast Guard and they immediately conducted a thorough search of the area," police said in the statement.
The Coast Guard reported Petrocelli said his wife fell over the stern of the boat, while it was anchored, and that he was unable to rescue her.
At around 11:30 a.m., a boater reported finding a body in the water, about three nautical miles southeast of Montauk Point in the Atlantic Ocean. Ninive Petrocelli's body was recovered.
The Suffolk County Medical Examiner’s office is investigating the cause of death.
According to Newsday, the boat is registered to Frank Monte of North Bergen, N.J.
Monte is the general manager and CFO of John Petrocelli Construction, a Palisades Park, N.J., construction management and general contracting firm with high-end residential and commercial projects in its portfolio.
The couple were docking the boat at Montauk Marine Basin until Monday, according to Carl Darenberg, the owner.
Ninive Petrocelli was the principal in Cristol, an architectural glass company with a 5,000-square-foot showroom in the New York Design Center. Her husband is listed as the CEO of the company. Works in her portfolio included Bacarrat, Brown University, Saks 5th Avenue, Chanel, and the Miami Dade Cultural Center.
