CHICAGO (AP) — A southern Illinois man is accused in U.S. District Court of threatening the life of a federal judge in Chicago. Joshua Farner of Marion is facing two counts of mailing threats and one count of threatening to assault and murder a judge.

The indictment accuses Farner of sending the threatening letter to retaliate against the judge and impede, intimidate, and interfere with the judge’s official duties.

Prosecutors haven’t revealed a reason for the threats. The judge targeted by Farner hasn’t been named. It wasn’t immediately known if the 35-year-ol Farner has retained an attorney to speak on his behalf.
