Police have released new surveillance footage of one of the victims in the Gilgo Beach killings.

The video shows Megan Waterman at a Holiday Inn Express in Hauppauge in June 2010. Police believe she left the hotel shortly before she was killed.

Suffolk County Police Commissioner Rodney Harrison says police believe that Waterman left the hotel that night to meet her killer.

“I know you all are wondering why we are releasing this evidence, now years after the tragic passing,” says Harrison says. “Well I cannot speak to the investigative tactics used by my predecessors, I can only share my vision of being transparent going into the future on this case.”

Waterman’s body was found in an Oak Beach marsh along with nearly a dozen others between 2010 and 2011.

John Ray, a family attorney for one of the other Gilgo victims, says the footage is “barely adequate,” but it indicates the intention of police to start working with the public.

Ray has heard the 911 calls from victim Shannon Gilbert, which have yet to be released by police. He says it could bring light to the crimes.

“I believe that if the public hears that 911 tape, the first thing that will happen is they will completely lose faith in the former investigation by the police department,” Ray says. “The second thing, they will be shocked at what they hear.”

The killer or killers responsible for the Gilgo Beach murders have still not been found.

As part of advanced efforts by police, the Gilgo News website has been rebuilt so more information can be given to the public as quickly as possible.

Police are offering a historic $50,000 reward for any information leading to an arrest. That is the biggest reward offered in Suffolk County’s history.

Anyone with any information is asked to call Suffolk County Crime Stoppers at 1-800-220-TIPS.
