The version most people have heard goes something like this: a man in a rabbit costume lives beneath a railroad overpass on the edge of Fairfax County, Virginia. He appears on Halloween. He carries an axe. And somewhere behind the legend, there is a burned asylum, a crashed prison transport, and a list of names carved into the concrete of a bridge that locals have called Bunny Man Bridge for decades.

It is a complete story. It has an origin, a setting, a recurring villain, and a calendar date. It has the architecture of something that must have started somewhere real. It did—just not the way the legend says.

This is an urban legend. It is classified as collaborative regional folklore that expanded from two documented 1970 incidents involving a person in a rabbit-like costume in Fairfax County, Virginia. The asylum, the bridge killings, and the supernatural appearances were added later. No verified records support the asylum story, the killings, or any supernatural connection to the Colchester Road overpass. What can be documented are two contemporaneous newspaper reports, a Fairfax County archivist’s investigation, and the mechanism by which a strange local story became a full mythology.

What the 1970 Reports Actually Said

In October 1970, two separate incidents were reported to Fairfax County police and covered in local newspapers. In the first, a couple parked near the Guinea Road area reported that a man dressed in a white rabbit costume approached their car, accused them of trespassing, and threw a hatchet through the vehicle’s window. In the second incident, reported days later, a security guard encountered a man in a similar costume on a home under construction, again making statements about trespassing and wielding an axe-like tool.

Both accounts were treated as reports of a threatening individual, not as something paranormal. The descriptions varied in detail—the wording of the costume, the exact nature of the weapon, the specific location—but the costume and the aggressive trespassing language were consistent across both. The person was never identified. No arrest was recorded. The incidents appeared in print and then went quiet.

Brian Conley, a researcher at the Fairfax County Public Library, conducted the most thorough documented examination of the legend’s origins. His work traced the story back to these two 1970 newspaper accounts, establishing them as the earliest verifiable source material. Nothing in county records or regional archives from that period matches the asylum narrative or any related criminal history.

That gap between the two newspaper reports and the elaborate mythology that followed is where the legend was built.

The incidents were strange enough to be remembered. A person in a rabbit costume, on a dark Virginia road, threatening strangers over trespassing—that detail is specific enough to stick. What happened next, in the years and decades after the reports faded from local papers, was the process folklore researchers call accretion: the gradual layering of new elements onto an original core until the additions become the story people know.

But before those layers are examined, the geography matters. The 1970 incidents did not take place at the Colchester Road overpass that would later bear the Bunny Man name. That association came later, and understanding how it shifted is part of understanding how the legend works.

The Details That Repeat—and Where They Come From

Once a regional legend attaches to a physical location, it stabilizes. The Colchester Road overpass—a concrete railroad bridge in Clifton, Virginia—became the fixed address of the Bunny Man story at some point after the 1970 incidents. The bridge offered what the original incidents lacked: a permanent, visitable site. It could be approached on a dare. It had the right atmosphere—industrial, isolated, framed by trees.

The details that circulate most widely in retellings share a structure. There is always a costume. There is always an edged weapon, usually described as an axe or hatchet. There is always a threat involving trespassing or property. These elements map directly onto the 1970 newspaper descriptions. They are the core the legend carried forward.

Around that core, later versions added elements that have no traceable source in the documented record. The escaped asylum inmate became a standard feature: a man named Douglas Grifon, or Marcus Wallster, or some variation, described as a patient from an institution that no longer exists, transported by train, surviving a crash near the bridge, and living in the woods afterward. Some versions add a date—1904 is common—and a list of victims. Some add a Halloween curse, claiming appearances repeat on October 30th or 31st.

None of these elements appear in county records, historical asylum registries, or contemporaneous newspaper archives. The named individuals do not appear in Virginia institutional records for the period cited. No train crash near Clifton matching the described event has been documented by regional transportation or historical sources.

The asylum story is, as far as the available record shows, a later addition. It provides a backstory the original incidents did not have—motivation, history, tragedy—which is exactly what a regional legend needs to survive across generations.

What Was Added, and When the Bridge Entered the Story

Tracking when specific elements entered the Bunny Man legend is difficult because urban legends travel through oral networks before they reach print. What can be observed is the pattern. By the 1980s and 1990s, versions of the story were circulating in Fairfax County schools and neighborhoods with the bridge as a central feature. By the early 2000s, the story had migrated online, and the internet did to it what it does to every regional legend with a physical location: it amplified the most dramatic version.

The online iterations introduced the named characters, the specific dates, and the language of the curse. These versions read as creepypasta—collaborative horror fiction built on a real place—rather than local oral tradition, though the line between the two is rarely clean. What the internet versions share with the 1970 reports is the costume and the weapon. What they added is everything else: the institution, the crash, the killings, the supernatural repetition.

The role of local Halloween culture should not be underestimated. The Colchester overpass became a Halloween destination. Groups of teenagers drove out to the bridge on October 30th and 31st. Local media covered the phenomenon. That annual repetition gave the legend a ritual calendar, which is one of the structural features that distinguishes a durable urban legend from a story that fades. Each Halloween retelling confirmed the bridge’s identity as the Bunny Man’s territory, regardless of what the 1970 reports actually described or where they actually took place.

Why the Legend Took Hold and Kept Moving

Fairfax County in 1970 was suburban and expanding, with stretches of rural road still framing the edges of development. The original incidents occurred in that transitional landscape—neither fully rural nor suburban, exactly the kind of space where the unfamiliar feels plausible. A man in a rabbit costume on a dark road is strange enough to be genuinely unsettling. It does not require supernatural enhancement to be disturbing.

But legends require more than a strange event. They require a story shape—a beginning, a reason, a threat that repeats. The 1970 incidents had the threat and the costume. They lacked the reason and the repetition. The asylum narrative provided the reason. The bridge and the Halloween cycle provided the repetition. Together, those additions transformed two unresolved newspaper reports into a complete folklore text.

Researchers who study how urban legends function note that the most durable examples combine a real, unresolved incident with a setting that can be visited and a villain who is human enough to be plausible but strange enough to resist easy explanation. The Bunny Man fits that model closely. The original costume is human—strange, but human. The unresolved identity of the 1970 suspect left a blank that the legend’s later elaborations could fill.

Local media participation reinforced the cycle. Annual Halloween coverage of the bridge, including stories that acknowledged the legend’s fictional elements while reporting on the crowds who gathered there, gave the story institutional repetition. A legend covered by local news each October is a legend that gets retold each October.

What the Evidence Actually Supports

The Bunny Man legend has a documented origin. Two incidents from October 1970, covered in Fairfax County newspapers, describe a person in a rabbit-like costume making trespassing accusations and threatening people with an edged weapon. Those reports exist. Brian Conley’s archival research at the Fairfax County Public Library identified them as the earliest traceable source for the legend.

Everything built on top of those reports—the asylum, the named individuals, the train crash, the bridge killings, the Halloween curse—lacks verified record support. The Colchester Road overpass is real. The crowds that gather there on Halloween are real. The legend itself, as a piece of regional folklore, is real in the sense that it exists and circulates and shapes local culture. What it is not is a documented criminal history or a record of supernatural activity.

The person from the 1970 reports was never identified. That unresolved detail is the one genuine mystery the legend carries. It is a small gap in a local record, not a buried institutional secret.

What survives is the image: a Virginia road in October, two newspaper reports that answered nothing, and a rabbit costume that turned out to be exactly the kind of strange, human, ordinary-and-wrong detail that legends are built to preserve. The bridge did not make the story. The story found the bridge. That distinction is where the evidence stops—and where the legend begins.
