The human remains found off Ocean Parkway, west of Cedar Beach, on March 29 have been determined to not be those of missing New Jersey woman Shannan Gilbert, officials announced Thursday.

As the investigation into Gilbert's disappearance continues, detectives are now trying to identify the latest remains found on the Long Island beach.

At a chilling Wednesday afternoon news conference in Yaphank, Suffolk County Police Commissioner Richard Dormer confirmed that a fifth body was found in the beach area.

"Obviously this is an unfortunate occurrence, that we now have another body found in the same area. Somebody's lost their life and that's a tragedy," he told reporters.

His words confirmed that what a Marine Bureau Police Officer discovered Tuesday night off Ocean Parkway near Gilgo Beach in Suffolk County are indeed human remains.

At the time, Police Commissioner Dormer would only say that "the remains were taken to the Office of the Suffolk County Medical Examiner in Hauppauge where an investigation will be conducted."

Police don't yet know if the fifth body is that of a male or female, nor can they estimate the victim's age or suggest a cause of death. Police say the remains were there for some time.

Helicopters, cadaver dogs and police using machetes scoured Oak and Gilgo Beaches all day and into the night, continuing their almost year-long search for fresh evidence in Shannon Gilbert's disappearance.

Gilbert is the suspected sex worker whose disappearance police were investigating last December when they stumbled on 4 skeletons wrapped in burlap dumped alongside Ocean Parkway in a spot that had all the makings of serial killer's boneyard. But Shannon Gilbert was not among them, she remains missing.

Suffolk County Police say the search for more evidence will resume on Monday, weather permitting.
