NYPD Denies Cops Are Suspects In Long Island Serial Killer Case

The New York Police Department is denying that two of its cops are suspects in the Long Island serial killings.

Ten sets of human remains, including four women identified as call girls, have been found along an isolated stretch of Jones Beach Island since December.

On Sunday, the New York Post reported that a current and a former New York City policeman who had both gotten into hot water for soliciting prostitutes while on the job were being eyed in the murders.

The ex-cop resigned in the 1990s when his bosses learned he was paying for sex when he was supposed to be fighting crime.

The other policeman is still on the force, but was reassigned to a desk job after he was arrested in a sting operation for allegedly assaulting a prostitute. No charges were brought against him however.

NYPD brass denied the New York Post report.

"No NYPD officer has been identified as a suspect," NYPD spokesman Paul Browne told Newsday. "I have no information that an individual who retired 20 years ago is a suspect either."

It was also reported today that an unnamed NYPD officer was one of the last people to contact one of the victims before she died. Maureen Brainard-Barnes, a Connecticut call girl who disappeared from Manhattan in 2007, was contacted by a cop living on Staten Island. The details of their conversation are unknown.

Investigators believe there could be as many as four killers responsible for the slayings.

In a psychological sketch of the possible killer, The New York Times reported last month that some investigators think the murderer might have a law enforcement background.
