Jean Moss, 90

Jean Moss, a 90-year-old white woman, was fatally shot Friday, Aug. 5, in the 23800 block of Bayview Court in Santa Clarita, according to Los Angeles County coroner's records.

Deputies responded to an emergency call about 3:40 p.m. in the community of Bridgeport, a quaint and upscale neighborhood.

Jean Moss's daughter, who was inside a home when she heard three gunshots, ran out and discovered the bodies of her 90-year-old mother in the front seat of a car and her 95-year-old father Leo in the back seat. The daughter’s husband, who has since been identified as Martin Strassner, 64, was still in the driver's seat.

Martin Strassner apparently picked up his in-laws from their home in West Hollywood on Friday, drove them to his house in Valencia, shot them to death in the driveway and then turned the gun on himself, officials said.

Authorities said the murder-suicide appeared to have been planned in advance by Strassner. He was reportedly depressed, but no motive has been determined yet.

"It looks like he planned it and thought about it," said sheriff's Homicide Lt. John Corina. "He had a note, he had a gun."

Inside Strassner's four-door car, investigators found a handgun on his lap and a suicide note.

As detectives continued their investigation, onlookers began to gather behind the yellow police tape of Bayview Court, a cul-de-sac, while children rode bicycles and skateboards. Neighborhood residents said no crime of any sort had ever occurred before in the tight-knit community. All expressed shock.

"I'm at a loss for words," said Olga Echenique, an eight-year resident. "I can't believe it has happened in our neighborhood. Our kids play outside. Our neighbors are sweet; we give each other our house keys.

"Nothing like this has ever happened in the six years I've lived here," Francisco Gamero said. "This is a quiet neighborhood."

Anyone with information about the shooting 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.
