On the evening of April 16, 1960, a young woman from McAllen, Texas named Irene Garza went to church for confession. She never returned home. A week later, her body was found floating in a canal. Decades would pass before the priest who murdered Irene was brought to justice in a historic case for the church and the Rio Grande Valley.
