OAKLAND (CBS SF) — A suspect found sleeping in a car with a handgun was shot and killed by police officers in Oakland Saturday morning and Oakland mayor Libby Schaaf has promised to determine if the officers’ actions were appropriate.

Police were notified around 7:30 a.m. of an unresponsive driver who had a gun in a car near the Lakeshore Avenue off-ramp from Interstate Highway 580, according to Oakland police Chief Sean Whent.

Whent said officers blocked off the area and spent roughly an hour trying to wake the suspect.

Officers deployed beanbag rounds at the car in an attempt to get the driver’s attention, but police said the driver was unresponsive.

Officers then approached the car with a metal pipe to break the passenger-side window in an attempt to talk to the driver, police said.

At that point, the officers were able to confirm that a gun was inside the car, according to police.

Whent said that during the last attempt to contact the driver, officers approached the car, the person woke up and then a confrontation ensued.

One officer deployed a Taser and another officer used a gun, Whent said. The driver was struck by bullets and transported to Highland Hospital, where he was pronounced dead, according to Whent.

Police said officers found a loaded gun with an attached illegal extended magazine and said the car had been used in a burglary that occurred last night in San Francisco.

The case is being handled by the U.S. Park Police, according to San Francisco police.

The Alameda County District Attorney’s Office is investigating the shooting, per the department’s policy, along with the Oakland Police Department’s homicide unit and its internal affairs division.

There were 12 officers on scene who are being interviewed and Whent said investigators are reviewing the footage from their body-worn cameras.

In a statement released by her office Saturday, Oakland mayor Libby Schaaf said all uses of force are taken seriously and should be closely examined “for the safety and assurance of the public and law enforcement.”

“I am actively making sure that the protocols and supervision we’ve worked hard to put in place as part of our police reforms are being followed rigorously as this shooting is thoroughly investigated,” Schaaf said. “Our community deserves all of the accurate and timely information that can be provided.”

The shooting is the first fatal officer-involved shooting since May 2013, according to police.
