Detectives are trying to figure out who abused a 4-year-old boy and left him for dead in his home, alone. Medics responded to 89 Ketcham Ave. minutes after somebody in the rear apartment of the house at that address called 911 Wednesday afternoon. When they arrived, they found Adonis Reed unconscious on the couch, and rushed him to a local hospital. Doctors there pronounced the boy dead. Nobody else was in the apartment when medics arrived.
