Authorities say a man shot by a carjacker who went on a shooting rampage through several Los Angeles suburbs has died. Deputy Ryan Rouzan of the Los Angeles County Sheriff's Department said Saturday night that deputies are searching for the gunman. Authorities in Southern California say they're searching for an armed man who carjacked a woman's SUV before shooting and injuring three other people. Rouzan says deputies believe the same man who stole the SUV next shot three people in the nearby communities of Norwalk and Whittier.
