Richmond police is doubling up street patrols in hopes of quelling any weekend violence that may stem from a rash of shootings and homicides this week that hit KCBS close to home. 56 year old Miguel Ramirez, a longtime custodian in the KCBS building, was killed by a stray bullet Tuesday night. KCBS reporter Holly Quan spent time in Richmond with the mayor, police and Miguel's family to see what's behind this spike in violence.
