Anahit Hayrapetyan, 63

Anahit Hayrapetyan, identified by the coroner's office as a 63-year-old white woman, died Monday, March 5, after being strangled in the 2000 block of West Whittier Boulevard in Montebello, according to Los Angeles County coroner's records.

Family members discovered Anahit Hayrapetyan and her husband about 11 a.m. in their apartment at a senior living center, the Los Angeles County Sheriff's Department said.

Coroner’s records show the woman had been strangled and suffered blunt force trauma to the body. She was pronounced dead at the scene.

The husband, Baghdo Hayrapetyan, attempted to kill himself with a knife after he strangled Anahit, according to officials.

Baghdo Hayrapetyan, identified by authorities as a 72-year-old white man, was taken to Los Angeles County-USC Medical Center in critical condition and remains hospitalized there.

There were no witnesses to the incident, but it was being investigated as a domestic-violence murder, the department said in a statement.

Some said the man may have been suffering from dementia.

"He would forget stuff all the time," friend Mary Delgado told KTLA News. "She always took care of him."

Sheriff's officials could not immediately confirm that the man had mental problems, but said it would part of their investigation.

Baghdo Hayrapetyan has since been charged with murder in connection with his wife's death. His next court appearance is scheduled for March 16 at the East L.A. Municipal Court.

Anyone with additional details about the death is asked to contact the sheriff’s homicide bureau at (323) 890-5500. Those wishing to remain anonymous can call Crime Stoppers at (800) 222-8477.
