Police are searching for a suspect allegedly connected to six robberies at 7-Elevens in Southern California early Monday that left two dead and three injured.
The robberies and shootings were in Ontario, Upland, Riverside, La Habra, Brea and Santa Ana – cities all near the Los Angeles area.
The shootings happened on National 7/11 Day, when customers can receive a free Slurpee at the convenience store.
The father of Matthew Hirsch, 40, who was working the overnight shift at a 7-Eleven in Brea, California, when he was killed just after 4 a.m. PT on Monday, said his son had recently gotten sober after dealing with drug addiction for years and had turned his life around after getting the job.

"He hadn’t had time to enjoy a normal life," Jim Hirsch said. "He goes through a struggle for goodness and it ends in a shooting."
7-Eleven urged stores in the area to close Tuesday and Wednesday nights for safety reasons.
