Special Agent Fox Mulder Case: 2X03/Blood Perpetrators of mass murders are divided into two classifications, the spree killer and the serial. The sudden violent outburst in a public locale and the suspect's disregard for anonymity or survival define the Franklin incidents as spree killings. The confounding element of these profiles is that, given their backgrounds, the perpetrators would be statistically more likely the victims of violent crimes rather than the originators. The killers were all middle income, responsible people. None with a history of violence. Relatives and friends reported only minor displays of dysfunctional behavior, sleep disorders, headaches, eating difficulties; but witnesses did report the last suspect displayed a claustrophobic reaction. I am convinced an outside factor is responsible, but I must concede frustration as to a determination of the cause. A residue discovered on the fingers of the most recent perpetrator was analyzed and reported to be an undefined but nontoxic organic chemical found on plants, perhaps remaining from gardening. There have been reported abductee paranoia in UFO mass abduction cases. I find no evidence of this to be the case. The single connecting trace evidence to the killings is the destruction of an electronic device at the crime scene: a pager, a fax machine, a cellular phone, a gas pump digital display. In all honesty, I have never had a more difficult time developing a profile. There is no way to know who will be a killer, or who will be killed.
