ORINDA -- A 32-year-old Concord man was identified Saturday as the man shot by a California Highway Patrol officer during a traffic stop Friday.

David Alcairo was shot once in his abdomen and transported to John Muir Medical Center, where he remained Saturday with injuries that were not life-threatening, Contra Costa County Sheriff's Office spokesman Jimmy Lee said.

Once he is cleared for release by medical staff, Alcairo will be booked into an Alameda County jail and he will face "multiple charges," though Lee did not specify what those would be.

The still-unidentified CHP officer who shot Alcairo had been assisting with an investigation of an earlier hit-and-run accident injury involving a motorcycle on Highway 24 west of the Caldecott Tunnel when he spotted Alcairo's silver Honda sedan -- which matched the suspect vehicle description in the hit-and-run incident -- parked on the shoulder of Wilder Road just off eastbound Highway 24, Lee said. An off-duty federal law enforcement officer witnessed the accident and called in the accident.

The CHP officer parked behind the Honda and at some point during his attempt to speak with Alcairo, the suspect began approaching the officer in an "aggressive manner" and "refused to comply with orders," according to Lee.

The officer, fearing for his life, opened fire, Lee said. No one else was injured in the incident.

The offramp remained closed late Friday as crews continued to investigate the scene but has since been reopened.

The case is still being investigated. Anyone with information on the incident can contact the Contra Costa County Sheriff's Office at 925-646-2441.
