Even though you hope it isn't deep down you kinda know it is his body. I figure they killed him because he was in the house when the 2 adults were killed and he is old enough to tell what happened and identify who did it. While I do believe William Balfour did it he wasn't alone because the Chicago Suntimes reports that someone parked that SUV on the block where it was found either Sunday night or early Monday morning and several residents of the block have verified that the SUV was not there before then even as early as Saturday morning so William has been in police custody and that can only mean someone else knows what happened as well and drove the car and abandoned the car because the case was getting too intense. I hate to think it but Julian could have still been alive and the person who drove the car could have just killed him because again he was old enough to identify them. The autopsy will be able to tell how long he was dead.
