Hundreds march in memory of man shot by police in Calif.

EL CAJON, Calif. — Alfred Olango, the unarmed black man shot and killed by police in a suburb of San Diego, was remembered in a demonstration yesterday organized by clergy members and supporters of Olango’s family.

Several hundred people gathered peacefully at a park in downtown El Cajon to hear speeches by religious leaders and then marched through the streets to police headquarters, where Olango’s family members joined them.

Olango’s father, Richard Olango Abuka, called for the resignation of the police chief and said his son’s death is a turning point in a peaceful struggle to change police practices. Other speakers demanded changes in how police respond to calls about people in mental distress.

The event came a day after two videos of the shooting were released by authorities, something the family and community leaders had urged.

The videos show the officer fired four times at close range almost immediately after Olango, 38, suddenly raised both hands to chest level and took what was described as a shooting stance. In addition to the videos, police showed the 4-inch electronic cigarette device Olango had in his hands when he was shot.

The shots came less than a minute after police arrived at the scene in response to Olango’s sister calling 911 and reporting he was acting erratically.

The videos were released after nights of unruly and, at times, violent protests in El Cajon.

The incident is the latest in a series of fatal shootings of black men that have roiled communities across the U.S. It came weeks after fatal shootings by police in Tulsa, Okla., and Charlotte, N.C.
