The victim had severe trauma to his face and when paramedics got to the scene, they recognized him as a homeless man. He was not wearing shoes or pants, and had only one sock on.

The victim had apparently been attacked and then sodomized with a tree branch, and doctors at Northwestern Memorial Hospital had to remove part of the branch, which was lodged in the victim’s rectum, according to the lieutenant. While his condition was not immediately known, he is expected to survive.
