|“||Thirteen .... Are you impressed?||”|
Nothing about the Footpath Killer's past is revealed, not even his real name. What is known about him is that he worked at (and presumably owned) a secluded roadside gas station in Dumfries, Virginia. At an unspecified point in his life, he snapped for unspecified reason(s) (likely due to his low self-esteem from his stutter, should the profile about him be correct) and began brutally murdering people on backwoods trails, beating them into submission before shooting them in the head with a 9mm. The Footpath Killer eventually murdered thirteen people, though only six bodies were found.
Extreme Aggressor (Part 1)
Unable to catch the Footpath Killer, the authorities asked Jason Gideon to profile him, which the agent did, later using his profile in a lecture he gave at Quantico in 2005, right before returning to work with the BAU to help them track down the Seattle Strangler. After the unsub is killed and his latest victim saved, Gideon returns to Virginia and unknowingly (and coincidentally) stops at the gas station the Footpath Killer works at, later immediately realizing the clerk possesses every characteristic his profile stated the unsub would have when he goes inside to pay for his gas. After several seconds of awkward silence, in which the Footpath Killer notices Gideon's gun, Gideon leaves, only to hear a shotgun being chambered.
Compulsion (Part 2)
After forcing Gideon back inside, the Footpath Killer demands to know who he is. Gideon replies that he is an FBI agent and also claims (as a ruse) to know why he stutters. Ignoring this, the Footpath Killer marches Gideon into a back room, where he shows him pictures of his victims, feeding off from the surprise Gideon expresses when he finds out that there are thirteen victims and not six before demanding him to grab a nearby camera (presumably to record Gideon's murder or even have him record something else). When Gideon simply begins mocking him, the Footpath Killer grows increasingly frustrated and begins sputtering incoherently, keeping him occupied long enough for Gideon to disarm him, knock him out, and arrest him. The Footpath Killer is presumably incarcerated afterwards.
The unsub is a disheveled male aged in his twenties who would work a menial job and own an American-made truck that would be in a state of disrepair. Despite the murders being committed in secluded hiking trails, they were all unnecessarily violent, implicating the unsub lacked confidence and felt he would be unable to charm his victims. His low-impulse control meant that he could not stop killing until he was arrested. This low self-esteem likely stemmed from the unsub being ashamed of some physical limitation he possessed, most likely a stutter.
The Footpath Killer's victims were all killed on remote hiking trails and appeared to be random people who had stopped at his gas station. He would brutally attack his victims to incapacitate them, then shoot them at point-blank range in the forehead with a pistol, most likely a 9mm or something similar. His signature was leaving pictures of his victims, taken at the gas station, with their bodies. The Footpath Killer also kept copies of the pictures, presumably as trophies, and surrounded them with nonsensical scribbles and words. When he held Gideon at gunpoint, he used a 12-gauge Remington 870 pump-action shotgun.
The Footpath Killer seems to have been based on David Carpenter - Both were serial killers with similar nicknames, had severe stutters, attacked their victims in the wilderness, and used blitz-attacks to subdue them before shooting them in the head.
He may have also been based on Robert Hansen - Both were prolific serial killers who shot their victims with similar firearms, took trophies of some sort from their victims, were given nicknames for their crimes, and were both profiled as having stutters.
