Suffolk Police Commissioner Rodney Harrison says he is considering releasing new evidence and 911 audio connected to the Gilgo Beach murders.

Harrison told News 12 that new audio and video evidence could be released if it's determined that it could be helpful in the investigation.

He says his top investigators are reviewing 911 calls and other evidence that could spark leads in the cold case.

"We're still evaluating and, if possible, we will get it out hopefully sooner than later," Harrison says.

Shannon Gilbert's disappearance led police to discover 10 bodies in 2010.

"I said at the beginning when I was assigned here that we're going to be transparent," Harrison says. "But, we also need to evaluate anything we're going to release to the public, is it going to hinder the investigation? And that's one of the things we're taking a close look at. If we do share any information, be it video or audio, can it help for us to be able to possibly identify who our person of interest is? Or can it hinder the investigation?"

Gilbert's family attorney, John Ray, tells News 12 that Harrison told him that Gilbert's 911 tapes would be released without any hesitation.

"It's, I think, critical for the public to assist the police at this time in solving this case," Ray says

Ray says he still has faith that Harrison will still be transparent in the case.

There is no timeline into when a decision could be made, but Harrison has called the case a top priority.

He set up a task force, including the FBI and other law enforcement agencies, in an effort to find the killer.
