Joseph Hyungmin Son -- better known as UFC veteran Joe Son to diehard MMA fans -- was arrested Oct. 7 in Huntington Beach, Calif., on charges related to a 1990 Christmas Eve gang rape. Son, who was already in custody for an unrelated vandalism charge, was linked to the 1990 crime when he gave a DNA sample to authorities following a probation violation. A second assailant tied to the 1990 crime is still at large.
