OAKLAND — The 38-year-old woman who was shot and killed by Emeryville police Tuesday outside of Home Depot pointed a revolver at a security officer after being caught shoplifting, then tried to carjack at least three cars at gunpoint before pointing the weapon at police, the department said Wednesday.

Police say Home Depot security officers spotted the woman stealing knives and confronted her as she walked out of the Emeryville store at 3838 Hollis Street. That”s when the woman reached into her purse, shook off a towel and pointed a revolver at the officers, who backed off.

The woman fled and tried to carjack several cars outside a storage facility, before encountering two police officers and pointing a gun at them, according to Emeryville police Chief Ken James.

Police fired at least seven shots at the woman; officials did not say how many times she was struck. She was pronounced dead at the scene. One of the officers involved in the shooting was wearing a body camera, but did not turn it on until after the incident, James said.

Last month, the city of Emeryville approved the purchase of 50 body cameras, but the police department still has not done any training on the equipment and doesn”t yet have a policy on the cameras, he said.

“Body cameras are a matter of muscle memory,” James said. “And in a critical incident when adrenaline is flowing, especially when we haven”t done any of the training, it”s understandable why he forgot to turn it on.”

The footage has been reviewed and turned over to the Oakland Police Department, which is heading the investigation, along with the Alameda County District Attorney”s Office. Oakland police spokeswoman Johnna Watson said investigators were looking for video or still images from surveillance cameras at local businesses, including Extra Space Storage, where the shooting occurred.

“We are encouraging witnesses to come forward and provide any information, especially if they have cellphone footage,” Watson said. “We want to be transparent on every level.”

The two officers involved in the shooting — one male and one female — have each been with the department for at least seven years. Both have been put on paid administrative leave.

The shooting is the third officer-involved shooting in Emeryville in 35 years.
