This week, famed in-depth reporting program 20/20 will feature the murder case of Susan Woods—the victim at the center of Texas Monthly‘s most recent true crime podcast, Stephenville. In the episode, best-selling author and host of the podcast Bryan Burrough explores the diary of the killer himself, as well as the missteps by law enforcement and prejudices of a small-town Texas community that led this case to go unsolved for nearly two decades. Check out an exclusive clip from the forthcoming episode above.

The full two-hour episode will premiere tomorrow, January 19, at 8 p.m. CST. If you haven’t binged the full podcast series yet, make sure to listen on Apple Podcasts or wherever you get your podcasts.
