Four separate investigations were underway Tuesday after cell phone video surfaced of San Francisco police shooting a man in a wheelchair following an incident during which he allegedly stabbed an officer in the city’s South of Market district. Officers had responded to reports of a man vandalizing city vehicles in the area of 10th and Howard streets Tuesday morning at approximately 10:15 a.m. The intersection is next to the San Francisco Behavioral Health Services building. The man, whose name has not yet been released, was in a wheelchair but was not confined to it, San Francisco Police Officer Chiang said. "He was seen up and moving about a number of times," he said. The suspect had a rock and knife in his hand and was slashing the tires of some city vehicles in the area, Chiang said. He did not know what the man's motive was for vandalizing the cars
