The 77-year-old man who died in a University City crash has been identified, authorities said Thursday.
The fatal crash happened at 10:30 a.m. Wednesday at La Jolla Village Drive and Genesee Avenue.
Police said George Matteson of Pacific Beach was in a Volkswagen Golf when Soranun Booppanon, 39, allegedly ran a red light at the intersection.
Booppanon's Toyota Prius rammed into an Audi sedan and Matteson's vehicle, then hit a Nissan truck before all four vehicles skidded to a halt across the traffic lanes.
Matteson died at the scene of the pileup despite medics' attempts to resuscitate him. His female passenger suffered serious injuries. Booppanon and the motorist in the Audi sustained minor injuries, SDPD Officer Frank Cali said. The driver of the pickup was unhurt.
Booppanon was arrested on suspicion of vehicular manslaughter and driving while intoxicated, Lt. Kevin Mayer said. Investigators believe that Booppanon, a Rancho Penasquitos resident, was under the influence of some type of drug at the time of the crash, according to Mayer.
