A Hollywood resident was recently convicted for physically assaulting his 82-year-old mother and threatening a neighbor during an argument at the victim’s residence that occurred in early December.

The Los Angeles City Attorney’s Office prosecuted the case, which authorities said was a particularly graphic illustration of the toll domestic violence can have on families.

“Elder abuse is an outrage, all the more so when perpetrated by a family member,” Los Angeles City Attorney Mike Feuer said. “My office will aggressively prosecute anyone who abuses our city’s seniors.”

The defendant, Gevork Khachatryan, 55, was convicted during a five-day trial on four criminal counts of elder abuse, battery on an elder, battery and criminal threats. He was sentenced to 30 days in jail, 100 hours of community service and 52 Alcoholic Anonymous meetings. The court also issued a protective order for the victim, and stay away orders prohibiting the defendant from returning to the undisclosed location where the incident occurred.

Khachatryan had served as a caregiver for his mother since 2001 at her apartment in Hollywood. On Dec. 2, a neighbor heard screaming in the apartment, and went downstairs to investigate. The door was open, and the neighbor witnessed Khachatryan slap his mother with an open right hand on the left side of her face, according to prosecutors.

The neighbor attempted to intervene, but Khachatryan ran out and chased the neighbor through the apartment building’s courtyard. At one point during the altercation, Khachatryan ripped the neighbor’s shirt before the victim was able to escape. Witnesses called police, and officers arrested Khachatryan at the scene.

The case was prosecuted by deputy city attorney Susan Strick, of the Los Angeles City Attorney’s Office’s Family Violence and Elder Abuse Protection Unit.
