Cops scouring accused Gilgo Beach serial killer Rex Heuermann’s home in search of evidence tying him to new victims: sources

Cops scouring the Long Island home of accused Gilgo Beach serial killer Rex Heuermann are using body parts from potentially other victims to try to tie him to those murders, too, police sources say.

Authorities aren’t just looking for more links to the deaths of the four sex workers Heuermann is already accused of butchering — they also are trying to nail him on other murders that he hasn’t previously been publicly associated with, sources told The Post on Tuesday.

“They’re looking to match up previously recovered body parts but that didn’t match any of the identified victims,” a source familiar with the probe said.

The shocking revelation came as Suffolk County and state police investigators searched the 60-year-old married architect and dad of two’s disheveled Massapequa Park home, where he had been living with his wife and son and daughter, for a second straight day.

Photos show Suffolk County cops and state troopers stacking dozens of large brown cardboard boxes on the front porch of the home and inside two white tents erected on the front lawn — as vans and a trailer sat along the curb waiting to cart away the potential evidence.

A coroner’s van that was at the scene Monday had not returned as of midday Tuesday.
