In June 2013, authorities captured 66-year-old Walter Lee Williams, a former professor at the University of Southern California who was on the FBI's Most Wanted List. The fugitive faced child sex abuse charges, and was sentenced Monday for five years in prison (via LA Times). He will also have to register as a sex offender upon his release.

Williams quit teaching at USC in 2011 and traveled to the Southeast Asia and Pacific regions, claiming he was there to study sexuality. However, authorities say he sexually assaulted at least 10 boys, aged 9 to 17, during those trips.

During the trial, Williams pleaded guilty to the charges.
