The suspect in Tuesday’s Fresno shooting spree has been charged with first-degree murder in the killing of a California security guard days before his rampage. The Fresno District Attorney’s Office on Thursday announced the additional charge against Kori Muhammad in the killing of unarmed security guard Carl Williams, saying prosecutors were holding off on three additional counts of murder for Tuesday’s attack while investigators continue to gather evidence. Muhammad is due in court Friday. Muhammad told investigators that he decided to kill as many white people as he could after he learned he was wanted for Williams’s murder. Police had released his identity and description in connection with the killing, which was reportedly prompted by a dispute over the rules at the Motel 6 where Williams worked and Muhammad was visiting a friend on April 13.
