Also known as the Mad Gasser this phantom attacker sprayed paralyzing and nauseating gasses into people's homes during the night. The victims were unable to move for approximately forty minutes and extremely nauseous. The gasser was described as a man, or a woman dressed like a man, wearing all black and sprayed gas that smelled like flowers. The police received over a dozen calls in response to this attacker and at least twenty-nine victims, who were predominately female. The Phantom Gasser was never found.
Looking into the disappearance of Alvin Jenkins, Dean begins to question if it is one of their type of "gigs." Sam goes on to tell him that John had marked the area as a possible hunting ground for a phantom attacker, due to the county they are in having the highest missing persons per capita in the state. Still somewhat skeptical, Dean questions this idea by pointing out phantom attackers take people from their beds, while Jenkins was taken from a parking lot. Sam goes on to correct Dean by telling him there are different types of attackers, listing phantom gassers as one of them.
