A 25-year-old man has been identified as the primary suspect in Saturday's fatal car bomb explosion outside a fertility clinic in Southern California's desert resort city of Palm Springs, authorities said on Sunday.

Investigators are combing through the writings of a 25-year-old man believed responsible for an explosion that ripped through a Southern California fertility clinic over the weekend
