Luis Alberto Quiñonez, 19, was shot and killed on September 8, 2019, while sitting in a car with his girlfriend in San Francisco’s Crocker Amazon neighborhood. His girlfriend was also shot but survived with a wound to her arm. The shooting was reported as retaliatory and linked to a long-standing feud that began in 2014, when Luis was wrongly accused of killing a former classmate, Rashawn Williams, who had been fatally stabbed after a verbal altercation. Surveillance footage later showed another boy was responsible for that stabbing, but the accusation against Luis persisted.

Police arrested the shooter, who was 17 at the time and is described as Rashawn Williams’ younger brother, after the ambush. Luis’ father, Rene Quiñonez, has criticized how the earlier case was handled and says the wrongful accusation contributed to the cycle of violence that ended his son’s life. Does anyone have information about the earlier 2014 investigation or the events in Crocker Amazon on September 8, 2019?
