File text
Jasper Post Box (AI31-PE)
BACKGROUND:
Agents arrived in the town of Jasper Crossing, Arizona after the communications department intercepted multiple phone calls to local authorities regarding "frozen people" in the streets. Four of the five dispatched agents became paralyzed upon arriving at the scene. Additional assessment teams were dispatched.
Variations of Identification Formulas were tried with ineffectual results. Agents resorted to using aerial photography to study the positioning of the paralyzed individuals. Soon after, agents discovered the event's "epicenter" to be the local post office.
Unaffected agents cleared the area of all paralyzed civilians, animals, and Bureau personnel before beginning to study the item. Agents deemed susceptible to the item were tasked with interviewing and re-informing the public away from the site.
The item was soon placed on a transport vehicle manned by unaffected agents. Air travel had been deemed too dangerous given the item's effect. Numerous reports of temporary paralysis were reported by civilians along the truck's route from Arizona to New York City.
