WHEATON, Ill. (AP) — A suburban Chicago judge has ordered a mental fitness evaluation for a Wisconsin man charged with shooting and seriously injuring an Amtrak conductor.

The (Arlington Heights) Daily Herald reports 79-year-old Edward Klein’s public defender told the DuPage County judge Thursday that she has “bona fide doubt” of the West Allis man’s mental fitness.

Klein is held on $1.5 million bail and charged with attempted murder and aggravated battery. Officials say he shot the conductor May 16 because he wasn’t allowed to disembark early at a suburban Chicago stop.

The newspaper reports that when the judge ordered the examination Klein said “do what you have to do, sir.”

The judge set a June 28 court date in hopes of having a report from the doctor who will evaluate Klein.
