For sixty-five years, he was known to millions of Americans simply as ‘The Boy in the Box’ or ‘America’s Unknown Child.’ On February 25, 1957, the battered body of a four-year-old boy was found tucked inside a cardboard JCPenney bassinet box in the Fox Chase neighborhood of Philadelphia. Despite 400,000 flyers distributed with utility bills, nationwide FBI searches, and decades of relentless homicide detective work, the child’s identity remained one of the most heartbreaking mysteries in American history. On December 8, 2022, Philadelphia Police stood before the world to announce that modern forensic genetic genealogy had restored his dignity and his name: Joseph Augustus Zarelli.
The Discovery in Fox Chase: February 1957
On a freezing February afternoon in 1957, a young muskrat trapper checking his traps along Susquehanna Road in northeast Philadelphia spotted a large cardboard box discarded in the brush. Inside, wrapped in a faded plaid blanket, lay the body of a severely malnourished boy aged between four and six years old.
Autopsy results revealed horrifying abuse. The child’s body was covered in surgical scars, his hair had been crudely cut short in clumps, his fingertips were shriveled from prolonged immersion in water, and he had suffered fatal blunt force trauma to his head. Fingerprints and footprints were taken, but matched no hospital birth records or missing child reports anywhere in North America.

The Massive Investigation and Decades of Grief
The Philadelphia Police Department launched the largest missing child search in the city’s history. Over 270 recruits conducted grid searches of the woods. The boy’s photograph was printed on over 400,000 flyers mailed across the country. Detectives Elmer Palmer and Sam Weinstein dedicated their entire careers and retirements to solving the case, even paying for the boy’s original burial in a potter’s field with a tombstone reading ‘Heavenly Father, Bless This Unknown Boy.’
In 1998, the body was exhumed from Mechanicsville Cemetery to extract mitochondrial DNA, which was entered into the National Missing and Unidentified Persons System (NamUs), but technology at the time was insufficient to identify distant relatives.
The 2019 Exhumation and Advanced Genomics
In 2019, Philadelphia homicide detectives, partnering with the Vidocq Society and forensic genealogist Dr. Colleen Fitzpatrick and Misty Gillis of Identifinders International, secured a court order for a second exhumation. Advanced forensic laboratory scientists successfully extracted minute fragments of nuclear DNA from degraded bone samples.
Bioinformaticians built an SNP genetic profile and uploaded the data to GEDmatch and FamilyTreeDNA. Within months, genealogists identified clusters of first- and second-cousin matches in Philadelphia and Atlantic County, New Jersey.
Naming Joseph Augustus Zarelli
By reconstructing extensive family trees of prominent Italian-American families in West Philadelphia, genealogists traced the child’s lineage to both maternal and paternal biological parents. On November 30, 2022, court-authorized DNA testing of living maternal relatives confirmed the match with 100% certainty.
The child was born on January 13, 1953, to an unmarried mother in Philadelphia. Birth certificates and baptismal records confirmed his name: Joseph Augustus Zarelli.
Ongoing Pursuit of Justice
On December 8, 2022, Philadelphia Police Commissioner Danielle Outlaw held a historic press conference, formally announcing Joseph’s identity. While both biological parents are deceased, investigators have identified living half-siblings and are actively pursuing homicide leads to determine exactly who was responsible for the child’s death and abandonment in 1957.
The identification of Joseph Augustus Zarelli represents one of the oldest and most emotionally resonant cold case breakthroughs in forensic history, joining landmark genealogical successes such as the Somerton Man Carl Webb identification and the Lady of the Dunes case.

The 1957 Fox Chase Discovery & Decades of Unidentified Inquiries
On February 25, 1957, the bruised and malnourished body of a young boy was found wrapped in a flannel blanket inside a cardboard bassinet box in a wooded area off Susquehanna Road in the Fox Chase neighborhood of Philadelphia. Dubbed “The Boy in the Box” and “America’s Unknown Child,” the case became Philadelphia’s most famous unsolved mystery.
In 1998 and 2019, the boy’s remains were exhumed from Ivy Hill Cemetery for modern forensic testing. However, early DNA extraction attempts produced degraded, fragmented mitochondrial DNA insufficient for definitive identification.
Whole Genome Sequencing & Definitive 2022 Identification
In 2021, Philadelphia Police partnered with forensic genetic genealogist Colleen Fitzpatrick and Astrea Forensics. Astrea extracted nuclear DNA from rootless hair and degraded bone fragments using specialized ancient DNA protocols, generating a comprehensive whole-genome sequencing dataset.
Genetic genealogists mapped family trees on GEDmatch, identifying both maternal and paternal family branches in West Philadelphia. On December 8, 2022, Philadelphia Police Commissioner Danielle Outlaw officially announced that “America’s Unknown Child” was Joseph Augustus Zarelli, born January 13, 1953, restoring his name after sixty-five years.
