Javier Arroyo, 59, was shot and killed on March 1, 2009, around 8:30 a.m. on Mission Street in San Francisco’s Excelsior District. His death was one of several homicides in the city during a violent stretch in early 2009 and drew attention to ongoing gun violence in parts of San Francisco at that time.

The circumstances leading to Arroyo’s shooting remain unclear. Authorities opened an investigation to determine a motive, but few details have been released about what happened or who was responsible.

Did anyone in the Excelsior District recall seeing or hearing anything unusual on the morning of March 1, 2009, that might help investigators?
