“We know that the carrier was shot this morning while he was making deliveries. … He was apparently shot in the arm, and he actually wanted to continue delivering his route for awhile but the supervisor convinced him to go get medical treatment.”

Reynolds says Johnson is a substitute carrier who’s been working the South Shore route one day a week for a year and a half.

Reynolds says Johnson was treated at South Shore Hospital.

Chicago police say no one is in custody.
