Rex Heuermann, 59, may be more than the suspected Gilgo Beach killer. Heuermann’s DNA has been entered into a statewide database, Suffolk police confirm, to see if it matches any other unsolved crimes.

Heuermann has been charged with the murders of three women and is a prime suspect in a fourth murder case. Now, investigators are looking into whether he is tied to the murders of the six other Gilgo Beach victims.

“Is Rex Heuermann part of those six? We'll wait and see, but everybody needs to understand that the task force will stay intact,” said Suffolk County Police Commissioner Rodney Harrison. “We're going to continue to work and see what we can do to bring closure to the other families that unfortunately are suffering.”

Heuermann lived in Massapequa Park, worked in Manhattan and was known to travel. He also owns property in South Carolina and Las Vegas. Commissioner Harrison told Team 12 Investigates that their work is far from over.

“We're not out of the woods and there are still bodies out there that we've discovered, that we still have to identify who the perpetrator is,” Commissioner Harrison said.

Investigators said Heuermann had been living a double life. He was an architect and a family man with a wife and two kids. However, he appeared to have a fascination with the Gilgo Beach murder investigation.

Police said he had searched more than 200 times for clues about their investigation and for information related to the victims. His emails were also linked to searches for violent pornography, according to court documents.

“A very, very bizarre lifestyle that he lived,” said Commissioner Harrison. “Two types of lives where he was a family man, architect, but when his wife would go out of town, some of the things that he participated in was very, very dangerous for our community.”

Commissioner Harrison said investigators have spoken with Heuermann’s wife, daughter and son. They have been cooperating with their investigation so far and appeared “shocked” by the allegations.

“We'll continue to work with them to see if there's anything else that we need to take a closer look at in connecting him to those bodies or any other bodies throughout the state,” Commissioner Harrison explained.

When asked whether police believe that Heuerman acted alone in the murders, Commissioner Harrison told Team 12 Investigates that “time will tell.”
