Haunted Lineage note: The original listing story about an escaped mental patient is part of the broader Bunny Man urban legend that has grown and mutated over decades. Fairfax County historian-archivist Brian Conley conducted extensive research to trace the legend's origins. He found no evidence of any insane asylum in Fairfax County, no record of inmates named "Douglas Grifon" or "Marcus Wallster," and confirmed that Lorton Prison did not exist until 1910 and was a D.C. corrections facility — not a Virginia state institution. The widely circulated internet version of the story (attributed to a "Timothy C. Forbes" and posted to Castle of Spirits around 1999) was found to be entirely fabricated.

Conley traced the legend's actual genesis to two documented incidents in October 1970, reported in the Washington Post: on October 18, Air Force Cadet Robert Bennett and his fiancee were in a parked car on Guinea Road in Fairfax County when a man dressed in a white bunny suit ran out, accused them of trespassing, and threw a hatchet through the car window. On October 29, security guard Paul Phillips encountered the same (or similar) figure at a construction site on Guinea Road, where the man chopped at a porch support with an ax while shouting about trespassers. Fairfax County Police investigated but could not identify the individual. Investigator W.L. Johnson marked the case inactive in March 1971 and confirmed there were no pre-existing stories of a bunny-suited individual.

By 1973, University of Maryland student Patricia Johnson documented 54 variations of the Bunny Man legend collected from teenagers in Prince Georges County, Maryland — demonstrating how rapidly the story had spread and mutated from the 1970 newspaper reports. By the 1980s, the legend had grown to include murders. Internet versions inflated the victim count to 32. The Colchester Overpass (Bunny Man Bridge) became the focal point of the legend by the 1990s. The story was also featured on Fox Family Channel's "Scariest Places on Earth" in 2001. Conley concluded the story meets all the hallmarks of an urban legend and that the legend of murders, hangings, or a ghost cannot be substantiated through news archives, police records, or historical documents at this time.
