The short answer to the question of whether The Heads of Sierra Blanca is based on a true story is no, and believe us when we say we tried to find even a slightly similar murder story occurring around or before 2007 in Texas. 

The podcast, which came out in September of 2019 is described as "an immersive experience that combines fiction, true crime and real interviews" but it seems like the fiction portion takes the cake.

According to the podcast, Ana Nuñez, Carlos Aniceto and Magdalena's own aunt, Lorena Salas, were murdered by a killer. Later, the murder was blamed on cartels and turf wars, but Magdalena wasn't buying that coverup story. Thus, the pod investigates the "truth" week after week.

Several listeners of the episodes that are out so far were quick to point out that the show "sounded scripted," and that it seemed fake even though the podcast presented these events as though they were real.

Fans of true crime podcasts weren't impressed that the creators of The Heads of Sierra Blanca weren't forthcoming with the lack of truth behind their story. Listeners pointed out small clues that gave it away, like the nieces not sounding convincing and the fact that one of the police characters is voiced by Machete's Danny Trejo.

There was also the fact that Magdalena had never put out a podcast before that raised some brows among seasoned true crime fans.
