PHOENIX (CN) - An Oklahoma man was sentenced Tuesday to seven years in federal prison for threatening to kill Arizona sheriff Joe Arpaio with a bomb.
Gregory Lynn Shrader, 56, of Jay, Okla., was convicted by a federal jury on Sept. 11 of threatening to kill Arpaio, mailing injurious articles and possession of explosive material by a prohibited possessor, the U.S. Attorney's Office said.
Shrader put an apparent explosive device addressed to Arpaio into a Flagstaff mailbox in April 2013, with a return address of a former business partner. He apparently wanted law enforcement to investigate his former partner, prosecutors said.
Arpaio, who calls himself America's toughest sheriff, is known for his tactics against immigrants.
