Fifteen-year-old William Billy Ray Lawrence of Houston was last heard from on June 4, 1973, when he told his father he was going fishing with friends at Lake Sam Rayburn and would be back in a few days. A letter postmarked June 8, purportedly from William saying he had found work in Austin, later proved to be false.

Investigators say William was lured to Dean Corll’s Pasadena home by acquaintances and held for three days, during which he was tied to a bed, abused and tortured, then strangled with a cord. After Elmer Wayne Henley Jr. killed Corll on August 8, 1973, Henley’s confession led police to multiple burial sites. William’s nude body was recovered August 9, 1973, in a shallow grave near Lake Sam Rayburn, wrapped in plastic sheeting and covered with lime.

David Owen Brooks later admitted involvement in William’s abduction and burial and was convicted of William Ray Lawrence’s murder on March 4, 1975; Henley was convicted on multiple counts and given consecutive life terms. Does anyone have memories or information about William’s last known movements or the people he was with that week in June 1973?
