Sacramento police have released video of Stephon Clark, a 22-year-old unarmed black man killed by officers in the backyard of his grandparents’ home on Sunday night. Two officers fired a combined 20 shots at Clark shortly before 9:30 p.m.

“The only thing that I heard was pow, pow, pow, pow, and I got to the ground,” Sequita Thompson, Clark’s grandmother, told The Sacramento Bee. “I opened that curtain and he was dead.”

A police department statement says: “Prior to the shooting, the involved officers saw the suspect facing them, advance forward with his arms extended, and holding an object in his hands. At the time of the shooting, the officers believed the suspect was pointing a firearm at them. After an exhaustive search, scene investigators did not locate any firearms. The only item found near the suspect was a cell phone.”

Local NAACP chapter president Betty Williams will meet with Sacramento Police Department Chief Daniel Hahn today amidst rising tensions stemming from the shooting. The NAACP released a statement saying: “While we respect the role of (SPD) in our community … these shooting(s) have angered, frustrated and frighten(ed) people in our community,” the statement said. “We are also frustrated with the justice system which fails to indict such killings. We are a community experiencing post-traumatic stress and as such the community and police relations(hip) remains one of mistrust.”

Clark had two young sons, Cairo and Aiden, and a fiancee, Salena Manni. A GoFundMe page established to benefit Clark’s family had raised almost $33,000 as of Thursday afternoon.
