context: The boy in the box was buried in Potter's field, which originally buried an unidentified person or an ointment. In 1998, the boy's body was excavated for DNA extraction and succeeded in collecting DNA from the tooth enamel. The boy was then buried again at the Ivy Hill Cemetery in Cedarbrook, Philadelphia. Coffins, tombstones and sanctuary services were all donated by the son of a man who buried a boy who died in 1957. When the boy was buried again, there was significant public interest and media coverage. The tomb had a large tombstone inscribed as 'Unidentified Children of America'. Residents of the city mourn the poor boy who died while being abused at a young age by caring for the tomb and decorating it with flowers and stuffed animals.
