Multiple sources confirm to News 12 that investigators believe one or more of the Gilgo Beach murders happened at the Massapequa Park home of suspect Rex Heuermann.

The accused Gilgo Beach serial killer lived with his wife and two adult children at that home. Suffolk County District Attorney Ray Tierney has said that Heuermann's family was away at the time of the suspected murders.

Neighbors say many people in the community did not want to be close to Heuermann because of the conditions of the house.

Following Heuermann's arrest in three of the Gilgo Beach murders, his wife Asa Ellerup filed for divorce on Wednesday.

"With her, the conversations were short and to the point," says Etienne Devilliers, a neighbor of Heuermann.

Devilliers says he has also felt bad for Heuermann's children. He says his son Chris is a "sweet, special-needs kid." He says Heuermann's son just got a dog who is his only friend.

Heuermann's daughter Victoria worked for her father's firm, according to the company's website.

Devilliers says the daughter seemed like a nice girl and was very quiet.

News 12 tried to speak with Heuermann's sister-in-law who lives nearby, but she declined to comment.

Heuermann's brother, Craig Heuermann, now lives in South Carolina. He pleaded guilty to criminally negligent homicide in 1988 after killing a police captain in a head-on collision near their Massapequa Park home. News 12 covered the crash over three decades ago.

Heuermann's daughter Victoria worked for her father's firm, according to the company's website.

Suffolk County Police Commissioner Rodney Harrison tells News 12 that Heuermann's wife and children were shocked by the allegations.

"Very bizarre lifestyle, he was a family man, architect, but when his wife was out of town, the things he would participate in were dangerous," Harrison says.
