In February 1957, a young man hunting muskrats in a park north of Philadelphia chanced upon the badly beaten corpse of a young boy discarded in a cardboard box near the side of the road. Worried that police would reprimand him for hunting, he left the box where it was, and there it sat until days later when a college student discovered it again and alerted local police, according to an in-depth feature written by All That's Interesting.
The boy in the box was naked, wrapped in a plaid blanket, and was thought to be between 3 and 7 years old, per initial investigations. The cause of death was determined to be blunt force trauma and according to now retired detective sergeant Bob Kuhlmeier, "he appeared to be cleaned and freshly groomed with a haircut."
