All anyone needs to know about Horne is that he recycled David Lifton's ridiculous body snatching theory that proposes clandestine surgery was conducted on the corpse to disguise the true nature of the wounds.

Peter Janney and Doug Horne : William L Mitchell testified at the Mary Meyer murder trial in DC in 1965, and then disappeared.
He resided at the time at 1500 Arlington Blvd, Apt. 1022, Arlington, Va.
