One of Accused Long Island Serial Killer’s Victims Likely Killed Inside His Home, He’s Now on ‘Suicide Watch’: Reports

Rex Heuermann, the suspect charged in the deaths of three women found on a Long Island beach over a decade ago, is believed to have killed at least one victim at his home in Massapequa Park, according to what law enforcement sources told CBS News.

It’s currently unclear which victim investigators believed was murdered in 59-year-old Heuermann’s residence, but they reportedly said his two children and wife were away from home when the killing happened.

As CrimeOnline previously reported, Heuermann is charged with the death of three of the four women known collectively as the “Gilgo Four.” The bodies were found within days of each other on Gilgo Beach in December 2010. All four women were buried in burlap sacks.

Heuerman has been charged with six counts of murder in the deaths of Melissa Barthelemy, 24; Megan Waterman, 22; and Amber Lynn Costello, 27; and is the prime suspect in the death of 25-year-old Maureen Brainard-Barnes.

Police arrested Heuermann on July 13 in Manhattan. He remains behind bars at the Suffolk County Correctional Facility in Riverhead, without bail. Suffolk County Sheriff Errol Toulon said Heuremann is in an isolated cell alone and appears to be “comfortable.”

“He’s in the cell by himself, he’s receiving all the services that any other person who’s incarcerated will receive,” Toulon told WCBS 880.

“It seems like he’s very comfortable in his cell and his surroundings. He’s indicated to my staff that he would not be any issue to us and would be extremely compliant, so we’ll see how that plays out in the days and weeks ahead.”

He’s also on suicide watch, according to Toulon, who said it was “pretty standard for someone that comes in with a case of this type of notoriety.”

“Our mental health staff will re-evaluate him to see if they actually do feel he has suicidal tendencies.”

Toulon added that they monitor and videotape Heuermann 24 hours a day, and “all inmate movement stops” when he is moved from one place to another within the jail.
