In this episode, we take a closer look at two of the investigators’ suspects: Steve Schafer and John Gilbreath. Witnesses told authorities that Schafer was the leader of a local Satanic group whose members included Shane and Sally, though Schafer says he was never part of the group. Gilbreath is the man who, in 2017, was found to have suspicious evidence in his home, including a lock of hair, a fingernail, and notes about Shane and Sally's murders. While authorities have since found that the DNA from this evidence doesn’t match Shane or Sally, Sheriff Nick Hanna says Gilbreath's behavior after the murders—repeatedly claiming to know details about the killings—still arouses suspicion.
