FRESNO, Calif. (AP) — A man who said he was fed up with racism against black people has been convicted of killing four white men in a race-related rampage in California’s Central Valley. Fresno County prosecutors say Kori Ali Muhammad was convicted Wednesday for the April 2017 attacks. On Friday, he withdrew a previous insanity plea and is expected to face life in prison without parole. Prosecutors say Muhammad, who is black, killed a motel security guard he felt disrespected him, then nearly a week later went on a murderous attack through downtown Fresno. His recorded confession was played at trial.
