"The suspect, who was not named because he is a juvenile, was one of a group who approached someone using a cellphone in the street at around 11pm on Saturday, December 14, according to the San Francisco Police Department.
One of the suspects demanded the cellphone and another suspect produced a handgun while others were going through the victim's possessions, the police said.
"The victim offered no resistance and was complying with the robbery suspects demands when the armed suspect shot the robbery victim," San Francisco police said in a statement. "The shot glanced off the victims face and struck one of the robbery suspects, killing him."
