The Greenbrier Ghost

Before Mothman, West Virginia gave us...

the only trial on Earth where a ghost's testimony - hearsay testimony at that - convicted a man!

Interred in nearby cemetery is Zona Heaster Shue. Her death in 1897 was presumed natural until her spirit appeared to her mother to describe how she was killed by her husband Edward. Autopsy on the exhumed body verified the apparition’s account. Edward, found guilty of murder, was sentenced to the state prison. Only known case in which testimony from ghost helped convict a murderer.
