WALNUT CREEK  (AP) — A Southern California woman was killed, a second woman was hospitalized and a Walnut Creek motorist faces charges after a pickup truck jumped a curb and hit the two women on a Walnut Creek sidewalk, police said.

Contra Costa County Coroner’s Office identified the woman killed as Sherry Hicks, 52, of Santa Barbara.

The driver of the pickup truck, Hossein Tabrizi, 53, suffered minor injuries in the crash Saturday and was arrested on suspicion of vehicular manslaughter, said Walnut Creek police Lt. Lanny Edwards. He was being held on $50,000 bail, Edwards said.

The Contra Costa Times reported that the impact of crash was so powerful that it sent Hicks flying into the air and onto a center median strip. She died at the scene, police said.

Tabrizi had to be extricated from the truck, which was jammed between a retaining wall and a street light pole after the crash.

Investigators have not determined how fast the truck was going, or if alcohol or drugs contributed to the crash.

The woman who survived remained hospitalized in “very critical condition,” Edwards said. Her name or details about her injuries have not been released.
