How Det Jeff Bennett Used Genetic Genealogy To Solve The 47-Year Old Murder Of Carla Walker

Author: Robert Riggs February 22, 2022 Duration: 38:04

Fort Worth Cold Case detectives solved the murder of 17-year-old Carla Walker after it had gone cold for nearly five decades.

They analyzed old evidence using genetic genealogy and new DNA extraction technology pioneered by Othram, a forensic genealogy lab in the Woodlands, a suburb of Houston. 

17-Year Old Carla Walker Abducted in August of 1974

Othram matched the DNA to a test submitted to a genealogy site by a member of the killer’s family tree. Othram did not disclose the relative’s name. 

Cold case investigators Jeff Bennett and Leah Wagner identified 78-year-old Glen McCurley, who was among the original suspects. McCurley confessed to them when confronted with the DNA evidence. 

Genetic genealogy was used in the Golden State Killer case, but this was the first time the technology made it to a courtroom.

Glen McCurley Sentenced To Life In Prison Under McDuff Capital Murder Law

McCurley pleaded guilty after two days of testimony in his capital murder trial in August of 2021.

More than 1,000 cases remain unsolved in Fort Worth alone. Paying for expensive DNA tests and travel expenses for investigators makes the task even more difficult.

Detective Jeff Bennett created the FWPD Cold Case Support Group in the wake of the Walker case. This nonprofit foundation accepts tax-deductible donations to help solve Fort Worth’s unsolved murders.

Robert Riggs has spent decades as an investigative reporter, and in True Crime Reporter, he applies that relentless, document-driven approach to the stories that haunt us. This isn't just a retelling of grim headlines; it's a meticulous walk through active case files, historical injustices, and the societal undercurrents that allow crime to flourish. Each episode feels like you're sitting across from Riggs as he lays out his notes, connecting dots between evidence, witness accounts, and the often-overlooked details that change a narrative. You'll hear the tension in the pursuit of truth, the weight of unresolved questions, and the quiet impact on communities and families left in the wake of violence. The podcast moves beyond the sensational to examine the cultural and systemic factors at play, offering a sober, deeply researched perspective. Listen for long-form narratives that build like a detective's board, where every piece of audio, every interview, and every document serves a purpose. It’s for those who want to understand the 'why' and the 'how' as much as the 'who,' presented with the clarity and authority of a seasoned journalist who knows the terrain. This is a journey into real stories, handled with the care they demand, and it naturally becomes an essential listen for anyone fascinated by the intersection of human behavior, justice, and the news.
