COLD CASES SOLVED

In 1969, a 16-year-old girl was murdered in California, leaving investigators with a mystery that would span more than half a century. Decades later, renewed investigative work helped identify Joanne Yvonne Burdick and brought attention to a suspect known as the Crew Cut Killer. This episode explores how old evidence, criminal profiling, and persistent detective work can revive a case long believed to be beyond resolution.

For more than six decades, he was known only as the “Boy in the Box,” one of America’s most haunting unidentified murder victims. His battered body was discovered outside Philadelphia in 1957, but despite thousands of leads, investigators could not determine who he was. Generations of detectives worked the case, while advances in DNA technology slowly created possibilities that investigators in the 1950s could never have imagined. In 2022, forensic genetic genealogy finally gave the child something investigators had been searching for for 65 years: his name, Joseph Augustus Zarelli. But identifying Joseph solved only one mystery, because the question of who killed him remains unanswered.

In October 1986, 23-year-old Teresa Ann Houck left the Baltimore club where she worked and was never seen alive again. Hours later, she was found shot to death in Druid Hill Park, leaving investigators with evidence but no identified killer. Nearly four decades later, a routine DNA database search produced the match prosecutors say finally gave the cold case a name.

For decades, investigators could possess a killer’s DNA yet have no suspect to compare it against. Investigative genetic genealogy changed that equation by allowing investigators to search for relatives rather than only exact database matches. The identification of the Golden State Killer demonstrated how a decades-old biological clue could suddenly become the beginning of an investigation rather than the end.

Joshua Wayne Crawford was found murdered inside his Maryland apartment on the day he turned 21, leaving investigators with a violent crime scene but no arrest. For 23 years, detectives revisited leads, retested evidence, and waited for forensic technology to catch up with the evidence left behind. Then, in September 2026, investigators announced an arrest—and revealed an extraordinary detail: the accused man’s name had apparently been sitting in a funeral visitation book for more than two decades.

On September 17, 2026, the GBI announced murder and related charges against Rashad Jackson in the 2020 death of Tyler Hall in Norcross, Georgia. Hall, 21, was found shot in his home in August 2020. The breakthrough came from advanced DNA and genealogy work by the GBI Cold Case Unit and Othram. Jackson is charged, not convicted, and the investigation remains active.

May 1973 two New Jersey sisters on a Florida Keys vacation were last seen hitchhiking on Stock Island; the next day their bodies were found in the woods off U.S. 1 in Key Largo. Fifty-three years later, forensic genetic genealogy named David Allen Snyder, a former Key West resident who died in Idaho in 2008. There will be no trial—only a name, a timeline, and the end of an unanswered question.

Two assaults, decades apart and a thousand miles from each other, sat in evidence rooms until the science caught up. In Lawrence, Kansas, a 2009 stranger rape on a darkened sidewalk finally produced a living defendant after a 1-in-848-trillion DNA match. In Fayetteville, North Carolina, a 1990 home-invasion rape at gunpoint was closed by genetic genealogy—only to find the Fort Bragg soldier already beyond the reach of a courtroom.

In 1986, a masked intruder terrorized East Jefferson homes and vanished. Nearly four decades later, a Georgia inmate already serving life was linked by DNA and a palm print to six aggravated rape counts. A Jefferson Parish jury needed only 45 minutes to convict him — a cold-case win built on evidence someone chose to save.
