Solving The Toughest Cold Case Murders With Forensic Genetic Genealogy

Solving The Toughest Cold Case Murders With Forensic Genetic Genealogy

Author: Robert Riggs May 8, 2023 Duration: 21:19

The Golden State Killer got away with 12 murders, 50 rapes, and more than 100 burglaries for over forty years before being caught. 

DNA evidence from his crime scenes never matched DNA samples in the FBI’s CODIS databases because he had never been arrested for murder or rape.

Eventually, investigators uploaded the profile to genealogy sites and identified a relative on the killer’s family tree.

It led to the conviction of James DeAngelo, a 72-year-old former police officer.

I’m investigative reporter Robert Riggs from inside the crime scene tape reporting how DNA analysis, called Forensic Genetic Genealogy, also known as FGG, is solving cold cases once thought unsolvable.

You can learn more about the Golden State Killer case in my episode titled How Cold Case Investigator Paul Holes Unmasked The Golden State Killer, dated April 25th 2022.

In my second episode about Forensic DNA, Dr. Suzanne Bell, who served on the National Commission of Forensic Science (NCFS), returns with more insight on the subject.

She coauthored Understanding Forensic DNA and emphasizes that DNA does not solve cases by itself. DNA results are always part of an extensive investigation.

At the end of our interview, Dr. Bell also provides advice on how to get into forensic science. It’s attracting large numbers of women. 

Here’s our discussion about forensic genetic genealogy.

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.
