After killing the child, Harris wrapped up the body and put it in the back seat of a borrowed 1996 Chevrolet Camaro, prosecutors have said. He drove to Chicago, dismembered the boy's body and wrapped the pieces in plastic bags that he tied to barbells and tossed into the Garfield Park Lagoon, according to prosecutors. The Cook County medical examiner’s office in 2015 did not determine a cause of death.
