Fifty-six years ago, a young schoolteacher went to church during Holy Week and never came home.

The next day, a few of her possessions were found scattered along the road outside the local Sacred Heart Church, as Texas Monthly recounted. One high-heeled shoe, a patent-leather handbag, a piece of crumpled white lace.

The following week, her body was found, fully dressed and badly bruised, retrieved from a canal in which someone had left her to decompose, her corpse washed clean of evidence. An autopsy found that she had been raped while comatose. MORE
