Prosecutors in California plan to drop charges against a surgeon and his girlfriend who were accused of drugging and raping women, Orange County District Attorney Todd Spitzer said Tuesday. Dr. Grant Robicheaux, 39, and Cerissa Riley, 32, had been charged in September 2018 by the county's previous district attorney of using their "good looks, charm" and drugs to lure women home to rape while they were unconscious or semiconscious.
