Police Tuesday searched the home of a Brooklyn man whose beaten and stabbed body was found Saturday floating in New York harbor, officials said.

Investigators were also looking into the cellphone records and other details of the life of Carmine Carini, 35, who was last seen Wednesday, three days before his body was discovered, said NYPD chief of detectives Robert Boyce.

Carini was identified through a fingerprint check after his body was found Saturday wrapped in a blue tarp and weighted down by a cinder block, Boyce said.

Carini, of Mill Avenue, had finished a five-year sentence in state prison for robbery in 2015. Investigators were unsure about the motive for his killing, according to Boyce.

“We have a long way to go,” said Boyce of the investigation.

Boyce said Carini’s father, also named Carmine, has had ties to organized crime but it was unclear if his son did, Boyce said. The elder Carmine Carini, 57, had a murder conviction overturned in 2007 and in July finished a 10-year sentence in federal prison for a robbery conspiracy conviction.

Federal court records showed he was convicted in 1983 for the murder of a man who was shot three times in the head and pushed out of a speeding car.

The father confirmed in a brief telephone interview that it was his son who had been killed but declined to comment further.
