A graphic video of the July 16, 2011 officer-involved shooting shows suspect Kenneth Harding struggling and bleeding on the ground

The San Francisco Police Department has released the names of the two officers involved in the July 16 shootout that ended in the death of 19-year-old Kenneth Harding.

Officers Matthew Lopez and Richard Hastings both fired their weapons at Harding, according to a letter from the department in response to a public records request from the American Civil Liberties Union of Northern California.

Hastings, who is paid about $108,000 per year, has been with the department since April 2001. Lopez, who is paid about $85,000 per year, was an Oakland and Hayward police officer before joining the San Francisco police department in April 2011.

Lopez received a medal of valor from the Oakland Police Department in September 2010 for coming to the aid of a California Highway Patrol officer who was shot and injured in a shootout during a robbery. Lopez had previously worked at the department in 2008 before leaving for the Hayward Police Department after union negotiations resulted in layoffs.

Lopez and Hastings were on administrative leave at the start of the Harding investigation, but are now back at work. Spokesman Albie Esparza said the department would not reveal their assignments.

“They're both good officers,” said Lt. Julian Hill of the Bayview station, where both officers were assigned prior to the shooting. “I have faith that they acted the right way and they had to make a decision and they acted on their training and experience.”

The fatal shooting occurred after Lopez and Hastings detained Harding for fare evasion at a Third Street light rail platform. Harding fled and began firing at officers, according to police. Hastings and Lopez fired back.

The medical examiner's office has determined that the bullet that killed Harding did not originate from a police weapon, but from a gun officers believe Harding used. Police Chief Greg Suhr said he thinks Harding accidentally shot and killed himself after a bullet from one of the officers' guns hit Harding in the leg, causing him to stumble and fall.

Esparza would not identify which officer shot the bullet that hit Harding in the leg, citing the ongoing investigation. He also declined to provide additional details about their histories with the department, including whether they had been involved in shootings before.

The department's investigation into Harding's shooting is near completion, Esparza said.
