News 12 has learned that a vehicle belonging to the accused Gilgo Beach serial killer is at a Suffolk Crime lab.

The Suffolk County district attorney’s office tells News 12 that the vehicle removed from the Rex Heuermann’s South Carolina property is the one he owned at or around the time of the alleged murders. They say they are awaiting analysis of all the items of evidence and will have more information once that process is completed.

Investigators linked Heuermann's vehicle to a cluster of calls they say he made from near his Massapequa Park home.

Investigators say it was one of the clues that led their focus to Heuermann as a suspect and later to charge him in the murders of Megan Waterman, Amber Costello and Melissa Barthelemy.

Retired NYPD detective and adjunct professor at John Jay College of Criminal Justice, David Sarni, says he expects investigators will check every square inch of the vehicle.

"From the headlights to the bumper and everywhere in between to see if they can find anything forensic to help solidify the evidence in the case in Long Island," Sarni says.

Sarni says even though it has been over a decade since the murders happened, if there is any chance there is forensic or any other evidence from the trucks, he is confident that investigators will find it.

He says with a cold case like the Gilgo Beach murders, Heuermann might not have been identified and arrested if evidence and had not been collected over a decade ago.
