Texas True Crime: Pure Evil | Full Documentary

In daylight, Houston's T.C. Jester Park is a haven for runners and cyclists. But 30 years ago, it was a shortcut for two innocent teenage girls - and what happened to them while cutting through the park at night was unspeakable. On June 24th, 1993, Elizabeth Peña and Jennifer Ertman crossed paths with what those involved in their murder cases have called "pure evil." "We've had bad crimes in Houston," said Don Smyth, a retired prosecutor. "But nothing compared to this." In our latest episode of Texas True Crime, ABC13's Jessica Willey sits down with those who saw this horrific case unfold - from police, witnesses and attorneys to the girls' family members, who used their pain to advocate for change. For the first time, one of the girls' attackers also speaks from prison.
