CHARLESTON, S.C. (AP) - A man has pleaded guilty to sending a letter threatening to kill a U.S. District judge in Charleston.
The Post and Courier of Charleston reported that 27-year-old Mario Dominic Brown pleaded guilty Wednesday to mailing threatening communications.
Federal prosecutors say Brown was in a state prison in 2010 when he wrote a letter threatening U.S. District Judge David Norton.
Brown initially was charged with two counts of threatening to assault a federal official and two counts of mailing threatening communications.
He accepted an agreement to plead guilty to a single count.
He will be sentenced later. He faces up to 10 years in prison.
Brown already is serving a 12-year sentence for armed robbery in a South Carolina prison.
