WALNUT CREEK >> A 16-year-old San Jose resident was arrested following a crash early Saturday that killed another teen from the South Bay, police said.

Authorities on Tuesday identified the boy who died in the crash as Gerardo Rosales, 15, of San Jose.

The wreck happened about 2:35 a.m. Saturday in the 1600 block of Newell Avenue, underneath an Interstate 680 overpass. Five people were in the car, and all were teenagers, authorities said.

Three of the other four occupants in the car ran or walked away from the crash scene, Walnut Creek police Lt. Bruce Jower said in a statement. It was not clear if any of those people were injured.

A Contra Costa County Sheriff’s Office deputy was first on the crash scene and performing CPR on a boy when police officers arrived, Jower said. An ambulance rushed him to John Muir Medical Center, about two miles away, where he was pronounced dead.

Police said they developed information identifying the driver and found him in San Jose. He was arrested there on suspicion of vehicular manslaughter and felony hit-and-run causing serious bodily injury or death.

Jower said police are still investigating and seeking more information. Those who may have some can contact police at 925-943-5844.
