Assistant Attorney General Tom Perez said Deryl Dedmon, 19; John Rice, 19; and Dylan Butler, 20, made "a sport of attacking African Americans" in the Jackson, Miss., area before they were linked to the fatal assault on auto worker James Craig Anderson.
Dedmon also pleaded guilty in state court Wednesday in connection with the murder and was given two life sentences. Rice has been charged by state authorities with assault. Butler has not been charged in state court. A state investigation continues.
