CANOGA PARK – Paramedics and traffic officers apparently overlooked the body of an elderly woman who was found in a car at a tow yard over the weekend, a day after the the vehicle was involved in a crash, authorities said today. She was identified as Shirley Williams, 72. Her son, who was critically injured, was identified as Steven Williams, 48. Both live in Paso Robles. The discovery was made yesterday, said Sgt. Paul Modrell of the Los Angeles Police Department’s Valley Traffic Division. “There was an accident Saturday and the car was impounded, and later it turned out there was another victim in the vehicle,” Modrell said. “Obviously, that is something they’re trying to figure out — how this could happen.” AD Quality Auto 360p 720p 1080p Top articles1/5READ MOREWhicker: Clemson demonstrates that it’s tough to knock out the champA local hospital spokeswoman said the two had been visiting family in Long Beach and the surrounding area on a holiday vacation. Hospital officials told her son, Steven, this morning about his mother’s death. The coroner’s office sent investigators to the tow yard late yesterday to examine and remove the woman’s body. Investigators did not speculate on a precise time or cause of death, he said. Officials said doctors may have a conclusion after the autopsy if this person died instantly or not. The initial traffic accident happened about 10 a.m. Saturday when a car, a gold 2003 Mercury Grand Marquis, driven by the woman’s son struck a parked car in a parking lot and crashed into a building in the 19200 block of West Ventura Boulevard in Tarzana. The car was then towed some seven miles to Howard Sommers Towing Inc. at 7891 Deering Ave. in Canoga Park. The body of the slightly built woman had been concealed beneath an air bag that had deployed during the accident, police said.
