Investigators used DNA evidence and genealogical research to identify the “Boy in the Box” as Joseph Augustus Zarelli, a 4-year-old from West Philadelphia.

But vexing questions remain. Authorities declined to release the names of Joseph’s parents and said they have not determined who was responsible for his death.

Smith said the PPD would not identify the parents – both of whom are deceased – out of respect for Joseph’s multiple living siblings.

His body was discovered bruised and wrapped in a blanket on a February morning more than 65 years ago in a wooded area near the corner of Susquehanna and Verree roads.

In an attempt to identify the boy, who was also referred to as America’s Unknown Child, fliers were mailed to city residents alongside their gas bills.
