The Greenbrier Ghost is the name popularly given to the alleged ghost of a young woman in Greenbrier County, West Virginia, United States, who was murdered in 1897. The events surrounding the haunting have led to it becoming a very late instance in American legal history in which the testimony of a "ghost" was accepted at a murder trial.

Background
The couple lived peacefully for a short time, but on January 23, 1897, Zona's body was discovered at her home by a young boy who had been dispatched to the house by Shue on an errand. The boy found Zona lying at the foot of the stairs, stretched out with her feet together and one hand on her stomach. The boy ran to tell his mother, who summoned the local doctor and coroner, George W. Knapp. Knapp did not arrive for close to an hour. By the time the doctor arrived, Shue had carried his wife's body upstairs to the bedroom, and laid her out on the bed. He dressed the corpse himself; this was unusual, as traditionally the job of washing and preparing the body for burial would be undertaken by the women of the community. Nevertheless, Shue dressed her in a high-necked dress with a stiff collar, and placed a veil over her face. Shue remained by the corpse while Dr. Knapp examined it, cradling his wife's head and sobbing. Knapp, noting the husband's grief, gave the body only a brief examination, noting some bruising on the neck. When he tried to look closer, Shue reacted so violently that he ended the examination and left the house.
Initially, Zona's cause of death was listed as "everlasting faint"; later, this was changed to "childbirth". Knapp had been treating her for "female trouble" for two weeks before her death, but whether she was pregnant or not is unknown.
Zona's parents were soon informed of her death. Mary Jane Heaster is reported to have said that "the devil has killed her" upon hearing the news.

The murder
Zona was buried on January 24, 1897. Although Shue initially showed great devotion to the body, keeping constant vigil at the head of the open coffin while it was being moved, his behavior soon began to arouse suspicion. During the wake, his grief changed repeatedly from overwhelming sadness to incredible energy. He allowed no one to come close to the coffin, especially when he cradled Zona's head with a pillow on one side and a roll of cloth on the other. He explained these additions by saying that they would help his wife "rest easier". Shue also tied a large scarf at the corpse's neck, explaining tearfully that it "had been Zona's favorite". Still, a strange looseness about the neck was noticed as the corpse was being moved to the cemetery.
For her part, Mary Jane Heaster was convinced that her son-in-law had murdered his wife. After the wake, she had removed the sheet from inside the coffin and tried to return it to him, but he refused it. She noticed an odd odor about it, so she washed it; the water in the basin turned red when she dropped the sheet in. The sheet then turned pink and the water cleared. The stain could not be removed, which Mrs. Heaster interpreted as a sign that Zona had been murdered. She began to pray, and every night for four weeks kept up her prayers, hoping that Zona would return to her to explain what had happened.

Burial
According to local legend, Zona appeared to her mother in a dream four weeks after the funeral. She said that Shue was a cruel man who abused her, and who had attacked her in a fit of rage when he believed that she had cooked no meat for dinner. He had broken her neck; to prove this, the ghost turned her head completely around until it was facing backwards.
Supposedly, the ghost appeared first as a bright light, gradually taking form and filling the room with a chill. She is said to have visited Mrs. Heaster over the course of four nights.

The haunting
Armed with the story told to her by the ghost, Mary Jane Heaster visited the local prosecutor, John Alfred Preston, and spent several hours in his office convincing him to reopen the matter of her daughter's death. Whether he believed her story of the ghost is unknown, but he did have enough doubt to dispatch deputies to reinterview several people of interest in the case, including Dr. Knapp. He was likely responding to public sentiment, as numerous locals had begun suggesting that Zona had been murdered.
Preston himself went to speak to Dr. Knapp, who stated that he had not made a complete examination of the body. This was viewed as sufficient justification for an autopsy, and an exhumation was ordered and an inquest jury formed.
Zona's body was examined on February 22, 1897 in the local one-room schoolhouse. Shue had "vigorously complained" about this turn of events, but was required by law to be present at the autopsy. He responded that he knew he would be arrested, but that no one would be able to prove his guilt.
The autopsy lasted three hours, and found that Zona's neck had indeed been broken. According to the report, published on March 9, 1897, "the discovery was made that the neck was broken and the windpipe mashed. On the throat were the marks of fingers indicating that she had been choked. The neck was dislocated between the first and second vertebrae. The ligaments were torn and ruptured. The windpipe had been crushed at a point in front of the neck." On the strength of this evidence, and his behavior at the inquest, Shue was arrested and charged with the murder of his wife.

Trial
Shue was moved to the West Virginia State Penitentiary in Moundsville, where he lived for three more years. He died on March 13, 1900, the victim of an unknown epidemic, and was buried in an unmarked grave in the local cemetery. Mrs. Heaster never recanted her story of her daughter's ghost, dying in September of 1916. As for Zona, her ghost was never seen in the area again.

A modern explanation of the red sheet
The state of West Virginia has erected a state historical marker near the cemetery in which Zona Shue is buried. It reads:
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 a ghost helped convict a murderer.
