The U.S. Court of Appeals for the 11th Circuit has affirmed a defendant’s criminal convictions for mailing a threatening message to a federal magistrate judge in Florida.

Judge Kevin C. Newsom issued an opinion Aug. 28 on behalf of a three-judge panel including Judges Charles R. Wilson and Robert J. Luck. While Lawrence Curtin based his appeal of convictions for threatening a federal official on what he claimed was insufficient evidence and his own incompetency to stand trial, the court found otherwise.
