The first incident was reported the evening of October 19, 1969 by U.S. Air Force Academy Cadet Bob Bennett and his fiancée who were visiting relatives on Guinea Road in Burke. Around midnight, while returning from a football game, they parked their car in a field on Guinea Road to talk. As they sat in the front seat with the car running, they noticed something moving outside the rear window. Moments later the front passenger window was smashed and there was a white-clad figure standing near the broken window. Bennett turned the car around while the man screamed at them about trespassing, including "You're on private property and I have your tag number." As they drove down the road they discovered a hatchet on the car floor.
When the police asked for a description of the man, Bob insisted he was wearing a white suit with long bunny ears, but Dusty remembered something white and pointed like a Ku Klux Klan hood. They both remembered seeing his face clearly, but in the darkness they could not determine his race. The police returned the hatchet to Bennett after examination. Bennett was required to report the incident upon his return to the Air Force Academy. It was later confirmed in Fairfax Police records that the man was wearing a bunny suit with ears, not Ku Klux Klan robes.
The second reported sighting occurred on the evening of October 29, 1970, when construction security guard Paul Phillips approached a man standing on the porch of an unfinished home in Kings Park West on Guinea Road. Phillips said the man was wearing a gray, black, and white bunny suit and was about 20 years old, 5 feet 8 inches (1.73 m) tall, and weighed about 175 pounds (79 kg). The man began chopping at a porch post with a long-handled axe, saying "All you people trespass around here. If you don't get out of here, I'm going to bust you on the head."
The Fairfax County Police opened investigations into both incidents, but both were eventually closed for lack of evidence. In the weeks following the incidents, more than 50 people contacted the police claiming to have seen the "bunny man." Several newspapers reported the incident of the "Bunny Man" eating a man's run-away cat. including the following articles in The Washington Post:
- "Man in Bunny Suit Sought in Fairfax" (October 22, 1970)
- "The 'Rabbit' Reappears" (October 31, 1970)
- "Bunny Man Seen" (November 4, 1970)
- "Bunny Reports Are Multiplying" (November 6, 1970)
