A 63-year-old San Ramon man killed Monday in a car crash on northbound Interstate 680 in Walnut Creek has been identified as Richard Adeokun, according to the Contra Costa County Coroner's Office.
Adeokun's 1974 Porsche collided with a Jeep just north of the North Main Street off-ramp just before noon on Memorial Day. He was unresponsive and transported to John Muir Medical Center, where he was pronounced dead.
There were two people in Jeep who suffered minor injuries but neither was hospitalized, according to the California Highway Patrol.
Information about the cause of the collision was not immediately available Wednesday morning, but the CHP previously said drugs and alcohol were not thought to be factors.
