An FBI Black Hawk helicopter equipped with high-tech search ability will be joining the hunt for remains left by a possible serial killer along New York's Long Island beaches, authorities said Friday.
Federal authorities issued a "no-fly" zone around the beach area to keep other aircrafts at a distance, but due to technical difficulties, the chopper will be grounded until Monday, The New York Post reports.
Land investigations continue as authorities searched a computer belonging to a pimp linked to a dead prostitute found along a beach highway on Long Island, hoping a record of her liaisons could lead them to a possible serial killer, law enforcement officials said.
The FBI examined the laptop of the pimp, New York City resident Akeem Cruz, for a record of Megan Waterman's customers, the official told the Associated Press, speaking on condition of anonymity because the official wasn't authorized to speak publicly about the matter.
Cruz, of Brooklyn, is not considered a suspect in the disappearance of Waterman and three other prostitutes whose bodies were found strewn last December near the side of a remote highway leading to Long Island's Jones Beach, the official said.
Cruz' attorney, Robert Napolitano, didn't immediately return a telephone message on Wednesday. He said earlier this week that his client -- currently imprisoned in Maine for a cocaine conviction -- would have granted permission for a search of his computer. Napolitano said his client has cooperated with investigators.
The U.S. attorney's office in Brooklyn declined to comment on the investigation into Cruz's computer.
Authorities say Cruz was one of the last people seen with Waterman, 22, of Scarborough, Maine, last June when she disappeared after traveling to a hotel in Hauppauge, N.Y., to meet clients for sex. In addition to the computer search, investigators have questioned hotel guests who stayed at the Holiday Inn Express at the same time Waterman was there.
Authorities believe a serial killer may be responsible for the deaths of Waterman and three other women in their 20s, whose bodies were found near hers. Police have not identified any suspects.
Police have since turned up six other sets of remains along the highway in recent weeks but have not definitively linked any of them to the deaths of the four prostitutes. The recent discoveries have prompted a wide-scale search along a 15-mile stretch of the highway.
On Thursday, the FBI deployed a fixed-wing plane with high-resolution photo imaging to help detect possible human remains. Detective Lt. Kevin Smith of the Nassau County Police Department said in a press conference Thursday that no human bones were found during a limited air and land search, though he said it will take a week to 10 days before the FBI images are available.
Police sources say the remains of the 10 victims could be the work of two serial killers, according to local press accounts.
A Nassau police spokeswoman, however, would not confirm to FoxNews.com that police are hunting two killers, saying only that authorities are waiting for reports from the medical examiner on the age, sex and condition of the latest remains found.
"We're still waiting for those reports," the spokeswoman said. "We can't confirm anything -- that's all speculative right now."
