This photo was taken during an investigation of Bachelor's Grove cemetery near Chicago by the Ghost Research Society (GRS). On August 10, 1991, several members of of the GRS were at the cemetery, a small, abandoned graveyard on the edge of the Rubio Woods Forest Preserve, near the suburb of Midlothian, Illinois. Reputed to be one of the most haunted cemeteries in the U.S., Bachelor's Grove has been the site of well over 100 different reports of strange phenomena, including apparitions, unexplained sights and sounds, and even glowing balls of light.
GRS member Mari Huff was taking black and white photos with a high-speed infrared camera in an area where the group had experienced some anomalies with their ghost-hunting equipment. The cemetery was empty, except for the GRS members. When developed, this image emerged: what looks like a lonely-looking young woman dressed in white sitting on a tombstone. Parts of her body are partially transparent and the style of the dress seems to be out of date.
Other ghosts reportedly seen in Bachelor's Grove include figures in monks' clothes and the spirit of a glowing yellow man.
