Johnny Wilson, 56, was found Jan. 17 lying on the floor covered in blood. His ears were bitten off, one eye was mauled, and he had bite wounds on his chest, upper body and head, according to the Cook County medical examiner's office, who ruled Wilson's death an accident.
Wilson's daughter, who was not immediately identified, turned over four adult pit bulls and two puppies to Chicago Animal Care and Control, where the dogs were being evaluated.
Neighbors told the Chicago Tribune that they were surprised by the attacks.
"She had them under control," Avantis Smith, a neighbor who has lived next door to the family for 20 years, told the paper.
Wilson was often seen walking the dogs in the neighborhood.
After evaluating the dogs Jan. 18, animal control officials said the four adult dogs would most likely be euthanized. But they were uncertain what would happen to the two puppies.
"Dogs don't normally attack people in their own homes, so there's a lot to investigate," Cherie Travis, commissioner of animal care and control, said.
