Deryl Dedmon and two other Rankin County, Miss. young men pleaded guilty Thursday to federal hate crime charges for the hit-and-run death of African-American James C. Anderson. One day after Dedmon was sentenced to two life terms in prison after pleading guilty to murder under a state hate crime law, he, and two other teens were charged and pleaded guilty in U.S. District Court to one count of conspiracy and one count of violating the federal hate crime law, according to the Clarion Ledger.
