EL CAJON, San Diego County (CBS / AP) -- Dozens of demonstrators on Wednesday protested the killing of a black man shot by an officer after authorities said the man pulled an object from a pocket, pointed it and assumed a "shooting stance."
Protesters who gathered outside the suburban San Diego police station in El Cajon chanted "no killer cops" and "black lives matter." Demonstrators who said they knew the man killed Tuesday identified him as Alfred Olango, a refugee from Uganda.
Agnes Hassan, originally from Sudan, described Olango as well-educated but mentally ill. She said she spent time in a refugee camp with Olango and that both of them suffered getting to the United States.
The man died after one El Cajon officer fired an electronic stun gun and another officer simultaneously fired his firearm several times, El Cajon Police Chief Jeff Davis told reporters at a news conference late Tuesday night. Davis did not describe the object, but acknowledged it was not a weapon.
Christopher Rice-Wilson, associated director of the civil rights group Alliance San Diego, questioned why one of the officers felt non-lethal force was appropriate while the other did not.
He was among those who identified Olango on Wednesday. Police Lt. Rob Ransweiler declined to confirm the victim's name but said he was in his 30s and believed to from Uganda.
Some protesters said Tuesday night that Olango was shot while his hands were raised in the air. Police disputed that and produced a frame from a cellphone video taken by a witness that appeared to show the man in the "shooting stance" as two officers approached with weapons drawn.
The fatal shooting happened just weeks after black men were shot and killed by police in Tulsa, Oklahoma, and in Charlotte, North Carolina, where violent protests broke out.
Candles and flowers were left Wednesday at the shooting scene, near bloodstains on the pavement.
Olango often hung around the strip mall and frequently seemed "agitated but he was never aggressive toward me," said Victor Hauer, who works at a nearby convenience store and sometimes bought the man food or gave him a few dollars.
Davis urged the community to remain calm and said the investigation will be thorough.
"This will be transparent," he said. "This will be looked at by multiple sets of eyes, and not just ours."
Police said they were called to the mall shortly after 2 p.m. by the victim's sister, who said he was "not acting like himself" and walking in traffic. The man refused "multiple" orders to take his hand from his pocket, then was shot after pulling out the object that authorities declined to describe, police said.
When detectives arrived, police say a female witness came forward and voluntarily provided cellphone video of the incident. Authorities released the single frame from it but not the video. El Cajon officers do not wear body cameras.
Other videos quickly surfaced showing the aftermath. In one posted to Facebook, an unidentified woman is heard telling police at the scene that the man was ordered to take his hand out of his pocket.
"I said: `Take your hand out your pocket, baby, or they're going to shoot you.' He said `no, no, no,' " the woman said. "When he lifted his hand out ... he did have something in his hand but it wasn't no gun, and that's when they shot him."
Another woman on the video wearing hospital-style work clothing identified herself as the victim's sister. She shrieked and cried, telling officers that she had called them to help her brother, who she described as mentally ill.
"I just called for help, and you came and killed him," she said.
Michael Ray Rodriguez was among witnesses who said the man had his hands in the air. He said that he was driving from his apartment complex past the shooting scene and saw a shirtless black man with his hands raised.
The officer "let go of the trigger and shot him again and again," Rodriguez told the San Diego Union-Tribune.
El Cajon is about 15 miles northeast of San Diego and has a population of about 100,000.
It is 69 percent white and 6 percent black, according to 2010 census figures, and has become home for many refugees fleeing Iraq and, more recently, Syria.
