Police were trying to determine why an elderly Chatsworth man shot and killed his wife then turned the gun on himself Monday.

The two were identified as Jerry Taylor, 73, and Diane Taylor, 67, and had been married more than three decades, said Los Angeles Police Department Detective Dave Peteque of the Operations-Valley Bureau Homicide Unit.

“According to family and friends, they get along, they go out, there is no evidence right now or no one told us of any health issues,” Peteque said.

The couple appeared to have a stable life, according to neighbors and police.

The husband “worked for the phone company for 40 years,” Peteque said. “He had a pension there.”

After hearing about the shootings, neighbors said they were in disbelief.

“It was absolutely shocking to think it was right here in my complex and then somebody I knew … just unbelievable,” said neighbor Joy Cross, 66, who lives in the same condo complex as the couple. “I’m a little shaken.”

The incident was reported at 7:05 a.m. Monday in the 10400 block of Canoga Avenue in Chatsworth, said Officer Drake Madison, an LAPD spokesman.

Based on the evidence and the investigation, “it is a murder-suicide,” Peteque said. “There’s no evidence at all that there was any kind of forced entry, ransacking or any kind of outside disturbance at all.”

Police learned about the shooting after a man called 9-1-1 stating that his wife was dead, Peteque said. The radio call went out to LAPD officers as a death investigation and the fire department also responded to the home, where they found the deceased couple, the detective said.

“We don’t see any injuries other than the gunshot wounds,” Peteque explained, adding that one neighbor did hear a gunshot.

A firearm was found at the scene, and family members were notified, Peteque said.

Kathy Mendoza, 52, said she lives eight units away from the couple. She did not hear anything before the incident but saw news vans when she left her condo.

“I was really shocked because it’s right in front of the pool and that’s where we hang out,” Mendoza said. “We see them, we wave, I make sure my music is low enough. It’s really shocking because everyone’s nice here.”

The woman previously worked as a manicurist, and did Cross’ nails.

She was “very talkative, very upbeat” and a positive person, Cross said.
