A former campus gynecologist at the University of Southern California has been charged in the sexual assaults of 16 patients. Dr. George Tyndall has been the subject of a Los Angeles police investigation for more than a year, says Newser. The patients involved in the charges range in age from 17 to 29. They had visited the student health center for annual exams or other treatment. 72-year-old Tyndall has denied any wrongdoing and could face up to 53 years in prison if convicted.
