Fourteen-year-old Terry Lee Lamb disappeared in July 1985 from Oklahoma City along with his mother, Linda Wheeler, and his siblings Angela, Michael, and Edward Mosely. The family’s disappearance prompted a search that ended in November 1985 when their bodies were discovered at a remote campsite near Sallisaw, Oklahoma.

Linda Wheeler had been beaten and stabbed to death. Herman Edward Lamb Jr., Linda’s ex-husband, was arrested and charged in the killings of Wheeler and the four children. He went to trial; the jury acquitted him of all charges and no one else has been charged in connection with the murders.

Lamb had a separate violent criminal history, including a conviction and long sentence for a 1977 rape and murder in Illinois and a no-contest plea to second-degree murder in Florida. He died in custody in 2020. Who has information about the family, the campsite, or the investigation that could shed light on what happened?
