Footage from a dashboard camera reveals that the suspect, Christopher Boone Lacy, 36, pulled a gun on CHP Officer Kenyon Youngstrom, 37, after he attempted to stop him for an alleged traffic violation, according to a press release from the Contra Costa County Sheriff's Office.
The shooting occurred around 8:30 a.m. in Alamo on southbound Interstate 680. Youngstrom and his partner were in two separate vehicles.
At 8:20 a.m., they "responded to a report of a traffic accident near Rudgear Road and Highway 680," a written report said. "Youngstrom was unable to locate the accident and cleared the detail. Officer Youngstrom agreed to meet his partner on southbound 680 to handle a dead deer on the side of the roadway. As he was on the way to the location, the beat partner notified Officer Youngstrom that he was going to conduct a traffic stop on a green Jeep Wrangler for an obstructed license plate."
Youngstrom had parked ahead on the side of the road and stepped from his patrol car to direct the green Jeep to the side of the road. The driver in the Jeep pulled up behind Youngstrom's patrol car, and Youngstrom walked toward the driver's side window. While Youngstrom and the driver, Lacy, briefly conversed, the other officer joined the two other parked cars, Lee said.
Then, without warning, Lacy pulled his gun and shot Youngstrom. Youngstrom's partner -- who is not being identified -- then shot Lacy in the head.
Both Youngstrom and the suspect were taken to John Muir Hospital. Lacy died there and Youngstrom remains on life support. The CHP told the press that they do not expect Youngstrom to survive, and that the doctors and his family will have to decide when to take him off life support.
Tonight, reisdents of Cordelia plan to hold a candlelight vigil for Youngstrom, whose wife and four children live there.
The CHP plans to establish a trust fund for Youngstrom and his family, but they have not finalized the details.
Meanwhile, investigators remain perplexed as to what motivated Lacy, a software developer who had been living in Corning, to shoot a CHP officer, the suspect's father told the press. The suspect had a loaded semi-automatic handgun, two magazines, and a knife in his car.
