Investigators in the Gilgo Beach murders case are digging into a grisly theory -- the suspected serial killer might have murdered his victims in his family's home.
Rex Heuermann lives in Massapequa Park, NY, roughly 15 miles away from Gilgo Beach, and since the spring, detectives have been looking into whether any of the victims were killed there ... according to a source who spoke to CNN.
According to the report, the source claimed the disappearances went down during times when Heuermann's family was out of town, leading investigators to theorize he potentially lured victims to the home.
Investigators think Heuermann would've had a big advantage using his own home, where he'd more easily be able to access materials like burlap bags ... and as you know, the 4 bodies found over a decade ago were wrapped in burlap.
As we reported, Heuermann was taken into custody last week in connection with some of the killings -- a total of 11 sets of human remains have been found at Gilgo, which included multiple sex workers, a man, and a toddler.
A lot of chilling details have surfaced in the week since his arrest ... including an account from a former escort who claims she went on a "date" with Heuermann while the murders were happening. She says he brought up the Gilgo Beach killings and was oddly enthusiastic about it.
