Yogurt Shop Murders Investigation: Seven False Confessions and a Broken System

The Austin yogurt shop murders investigation was compromised from the start. The detective who ran early interrogations, Hector Polanco, was implicated in at least seven false confessions across multiple cases. His most notorious failure: extracting a false confession from Christopher Ochoa in the 1988 Nancy DePriest murder, leading to the wrongful conviction of both Ochoa and Richard Danziger. Danziger suffered permanent brain damage from a prison assault. Austin settled for $14.5 million.

Despite this documented track record, Polanco interrogated suspects in the yogurt shop case during the early 1990s. He was eventually removed from the task force, but the contamination was already embedded. Eight years of questioning dozens of teenagers had allowed confidential crime scene details to spread through the community, making it impossible to distinguish genuine suspect knowledge from ambient information. When new detectives re-arrested the same four men in 1999, they treated community gossip as evidence of guilt.

Part 2 of this series provides a forensic breakdown of how the investigation derailed — the institutional failures, the confirmation bias, and the psychology of how communities under sustained trauma create scapegoats from the people least equipped to defend themselves. Essential listening for anyone following wrongful conviction reform and interrogation accountability.
