Prosecutors say Anthony Orban abducted a 25-year-old woman at gunpoint in April 2010 as she left work at the Ontario Mills Mall, forced her to drive to Fontana, then beat and raped her.
A San Bernardino County judge on Thursday ruled Orban can present a defense claiming he was mentally unconscious at the time of the attack because of the influence of the antidepressant drug, Zoloft.
Orban has pleaded not guilty by reason of insanity. He faces life in prison if convicted on all charges.
