Glen McCurley was living a quiet life in Fort Worth when new DNA evidence linked him to a notorious crime: the killing of a teenager named Carla Walker, more than 45 years prior. Police suspect it wasn’t his first murder — or his last. The story of how he got caught takes some surprising turns, including an amateur true crime podcast and a woman’s trip to CrimeCon:

The show, called Gone Cold Podcast—Texas True Crime, had a small audience at first, but one person who did listen to it was DiAnne Kuykendall, a retired mail clerk for the U.S. Postal Service in Fort Worth. “I had gone to high school with Carla,” she told me. “We didn’t know each other at all, but she had always smiled at me in the hallway. She made me feel good—the popular girl talking to someone like me. Listening to the podcast, I thought, ‘I wish there was some way I could pay her back.’ ”

Kuykendall decided to fly to Nashville to attend CrimeCon, an annual three-day true-crime convention that most recently attracted some five thousand fans (the majority of them women) who flock to see celebrity authors, podcasters, and broadcasters. She brought along eighty copies of a pamphlet she’d written about Carla’s case, which was based mostly on Strange’s podcast. She paced the hallways of the Gaylord Opryland Resort and Convention Center, passing out the pamphlets to the likes of Dateline’s Keith Morrison, Fox News’ Nancy Grace, and Paul Holes, a retired homicide investigator who’d helped solve the Golden State Killer case and who hosted a true crime show on NBC’s Oxygen network. “I’m sure everyone thought I was one of those crazy true-crime ladies,” Kuykendall told me.

Holes was intrigued by Carla’s case, and in April 2019, his producers called Wagner and Bennett. Oxygen was willing to pay $18,000 to cover the cost of DNA testing on Carla’s clothes. The detectives were thrilled.
