CHICAGO — A Minneapolis man who was shot by Amtrak police near Chicago’s Union Station has died.

Chicago Police spokesman Anthony Guglielmi said 25-year-old Chad Robertson died Wednesday, one week after being shot.

Robertson was taking a bus from Memphis, Tennessee, to Minneapolis and was on a stopover in Chicago when the shooting occurred.

According to family members, the transit officer fired at Robertson as he ran during an encounter near Union Station. The officer reportedly fired twice, striking Robertson once in the left shoulder.

Guglielmi says the man’s wounds were considered non-life-threatening at the time. He said the wounded man was found with cash and narcotics, but was unarmed.

Attorney Douglas Hopson of Chicago said the Minneapolis Star-Tribune that Robertson’s family will now considera wrongful death lawsuit against the officers involved.
