Sacramento police officers shot and killed a black man in his grandmother's backyard because they believed he was pointing a gun at them, police said.
But investigators say they did not find a weapon at the scene, only a cellphone near the man's body.
The fatal shooting of Stephon Clark on Sunday night was recorded by two officers' body cameras and from a police helicopter; that footage was released Wednesday.
The videos show a brief encounter between police and Clark, lasting less than a minute, from the moment one of the officers spotted him in the driveway and yelled, "Hey, show me your hands. Stop. Stop."
In the dark, the two police officers chased Clark into the backyard of his grandmother's home.
"Show me your hands!" one of the officers yelled. "Gun, gun, gun."
Then police opened fire. Clark crumpled to the ground, momentarily tried to crawl before falling motionless as more shots erupted around him.
Minutes after the shooting, as more officers arrive on the scene, a voice is heard saying, "Hey, mute," and the audio on the body camera cuts off.
Clark's grandmother said she was inside the house when the shots were fired and saw him with an iPhone.
Then they handcuffed his dead body.
