A former U.S. college professor who was recently placed on the FBI's notorious list of most wanted criminals has been arrested in Mexico.
Authorities say Walter Lee Williams was captured late Tuesday in the southern resort city of Playa del Carmen, just one day after he was placed on the FBI's Ten Most Wanted Fugitives list. The 64-year-old is facing four charges related to the sexual abuse and exploitation of children.
Williams is alleged to have traveled to the Philippines in 2011 to engage in sexual acts with two 14-year-old boys he met online the year before. He is also accused of taking sexually explicit photos of one of the boys.
Until 2011, Williams was an anthropology professor at the University of Southern California, where his field of study was gender development.
