The Boy in the Box

On February 25, 1957, 26-year-old college student Frederick Benonis reported discovering a boy's body in Philadelphia's Fox Chase neighborhood, in a cardboard box that had originally held a J.C. Penney bassinet. He had first seen the box two days earlier and delayed reporting it until hearing a radio report about a missing child.

The boy was estimated at 4–6 years old, naked and malnourished, with blunt-force trauma, recently cut hair and trimmed nails, and old scars indicating chronic prior abuse. He had no vaccination, school, or medical record on file anywhere.

Remington Bristow, an investigator with the Medical Examiner's office, pursued the case from 1960 until his death in 1993. A psychic tip led him to a foster home run by Arthur and Catherine Nicoletti, roughly 1.5 miles from the discovery site.

During a 1961 walkthrough of the Nicoletti home, Bristow found a bassinet matching the box in the basement, along with blankets cut to fit the home's metal cots.

When Bristow pressed Arthur Nicoletti to take a polygraph in the 1980s, Nicoletti declined. Nicoletti, a widower, had married his stepdaughter Anna Marie Nagle after his first wife's death.

In 1998, Philadelphia PD Lt. Tom Augustine, together with Vidocq Society members, formally re-interviewed the Nicoletti family and concluded they were not involved in the boy's death. That investigative interview — not DNA testing — is what cleared the family; the DNA work done around that time targeted the victim's own remains for identification, not a comparison to the Nicolettis.

A 1998 exhumation attempted to pull mitochondrial DNA from a tooth but yielded insufficient material for identification; the body was reburied at Ivy Hill Cemetery, still unnamed.

In 2002, a woman (most commonly identified in reporting as "Mary" or "M.") told a psychiatrist a secondhand account of a trafficked, beaten child she called "Jonathan." Investigators looked into it, but it was never substantiated — no corroborating evidence turned up at the claimed location, and neighbors didn't recall such a child.

A second exhumation in 2019 recovered a fuller DNA sample, handed to forensic genealogist Colleen Fitzpatrick of Identifinders International. Fitzpatrick described the recovered DNA as "like confetti," and genealogist Misty Gillis built out a family tree from cousin matches — described as reconstructing it "like a big Sudoku puzzle" — using GEDmatch as part of the process.

Between November 30 and December 8, 2022, police announced and confirmed the boy's identity: Joseph Augustus Zarelli, born January 13, 1953, to Augustus John Zarelli and Mary Elizabeth ("Betsy") Abel. His parents never married each other and both later married others; both are deceased.

At the identification announcement, Capt. Jason Smith said: "We have our suspicions as to who may be responsible. We're hoping to receive an avalanche of tips from this press conference, someone in their mid to late 70s or 80s who remembers that child."

The case remains an open homicide investigation, with a $20,000 reward offered for information leading to an arrest and conviction.

In July 1957, homicide detectives served as pallbearers at the boy's funeral and he was buried in a potter's field near Dunks Ferry in Northeast Philadelphia; the donated headstone read "Heavenly Father, Bless This Unknown Boy."

A new headstone was dedicated at Ivy Hill Cemetery on January 13, 2023 — what would have been his 70th birthday — reading "America's Unknown Child," with his name added.

In September 2024, eight more unidentified remains were exhumed from the same Northeast Philadelphia potter's field for the same DNA and genealogy process used to identify Joseph. None had been identified as of the most recent reporting found.

On January 13, 2026 — Joseph's 73rd birthday — the Vidocq Society announced a nationwide initiative applying the same identification method to other unidentified child homicide victims. Vidocq's Bill Fleisher called the case "the longest investigated, unsolved homicide" in the city's history, and said: "He's a symbol of all the children that haven't been identified yet, and the idea that they can be identified if the right resources and efforts are put forth in investigating these America's unknown children."

Whether the boy's death is tied to the Nicoletti household specifically. Bristow's theory — that the boy was the son of Anna Marie Nagle, hidden or disposed of to conceal a pregnancy outside marriage — was never proven and was effectively set aside by the 1998 investigative interview. No source confirms this was resolved through DNA testing; the exhumations were for identifying the victim, not for testing a biological connection to the Nicoletti family.

The specific manner of death within Bristow's theory (a fall from a third-floor window, a collapse near a pond, caretakers panicking) is Bristow's own speculative reconstruction, not an established fact.

Identity of the killer. Unresolved. Police have said they have "suspicions," but no suspect has been publicly named as of the most recent reporting found.

Anna Marie Nagle has been described in some retellings as "intellectually disabled" with "four children, three of them stillborn." We could not corroborate this specific characterization in any of the more detailed accounts of the case, including the two most thorough case threads available.

Bristow is often described as having worked the case unpaid for 36 years. That figure is arithmetically consistent with 1957–1993, but no source states it explicitly — treat it as a reasonable inference rather than a directly sourced fact.

The specific claim that the genealogical profile became usable in "spring 2021" isn't precisely sourced — the fullest account gives only a 2019–2022 window, and one source states the genealogists reached the identification internally in October 2021.

The claim that Philadelphia's forensic lab is now applying this process to "dozens" of other unidentified-remains cases "going back 60 years" is directionally consistent with the September 2024 eight-body exhumation and the January 2026 nationwide initiative, but no source gives this specific case count or time span.

Investigators have been vague about which ancestry databases were used beyond describing them as "public, consumer-accessible" (GEDmatch is the only one named in sourcing). No source explicitly frames this vagueness as a deliberate non-disclosure.
