Man Charged In Papa Potrero's Pizza Shooting Deaths

Of the three men arrested in connection with Sunday's Papa Potrero's shooting death, San Francisco prosecutors charged a 19-year-old Andres Siordia with one count of murder. If you recall, the double shooting, which is alleged to have stemmed from friction between "separate factions of the Norteno street gang," claimed the lives of SF residents Francisco Pena, 41, and Francisco Cornejo, 26.
