BROCKTON – Vandals spray-painted slurs and threw eggs at the West Street home where a former Crime Watch leader held what was billed on a Web site as sex orgies for adult men.

Police launched an investigation this morning into the vandalism at the 304 West St. home of Jay Dembling and the mayor denounced the vandalism.

“The behavior of the vandals that acted last night was even worse than the behavior they were targeting,” Mayor John T. Yunits Jr. said.

Vandals used black spray paint to scrawl slurs on the front door and front of the home near West Junior High School, the mayor and police said. The house and sidewalk were also egged.

A friend of Dembling, who painted over the slurs on the front door, said the vandalism occurred sometime this morning. He did not want to be identified.

The house is across West Street, three houses down from the school.

Yunits said authorities believe the vandalism occurred sometime overnight.

A visibly shaken Dembling stood inside his home this morning.

“I just want it to end,” he said. “I’ve done nothing wrong.”

Police Chief Paul Studenski said authorities were photographing the scene this morning and looking for other evidence that could help identify suspects in the case.

Sgt. Kenneth LeGrice said crime scene technicians from the Plymouth County sheriff’s office were called to assist in the case.

Studenski said he was stunned by the vandalism. “I’m more surprised that someone would draw attention to the place,” he said.

The vandalism comes less than a week after adult sex parties held at Dembling’s home near West Junior High School wound up in the spotlight.

According to a Web site and e-mails obtained by The Enterprise, Dembling hosted adult sex parties billed as “orgy’s” (sic) at his home, charging $10 for day parties and $15 for night parties.

Police are investigating whether any illicit drugs were used or if city licensing laws were violated. No charges have been lodged in regard to the parties.

Dembling is a well-known community activist who has served on Crime Watch and the Tri-Ward Committee that fought against excessive concert noise at the Belmont Street fairgrounds

West Junior High School students were sent home with a letter last week noting that additional adults would be stationed at the school to ensure the safety of the estimated 700 students in the wake of publicity about the parities.

The school noted in the letter that it does not appear any activity in the home was criminal.
