LOS ANGELES—After years of addiction, Matthew Hirsch was sober. He landed a stable job working overnight shifts at a 7-Eleven in Southern California, lived with his girlfriend in a nearby apartment, and spoke to his father every day.
Around 4:15 a.m. Monday, a masked shooter gunned down the 40-year-old clerk inside the convenience store. Authorities say it was one of six robberies by the same man at 7-Eleven stores across the region, senseless attacks that left two dead and three wounded.
