Three juveniles, friends since childhood, stole explosives from a mine; blew up part of a high school, three vehicles, and a gas station; and set four elementary school fires while eluding fire and police personnel from a region in Colorado for two years. Nicknaming themselves “Grems” after the movie Gremlins, the three often donned camouflage or military fatigues while carrying out their planned “missions.” Evidence sent to the Alcohol, Tobacco, and Firearms lab in San Francisco, California and a taped interview of a juvenile who identified his acquaintances and their crimes, and the sharing of information among fire investigation agencies combined to give officials a break in the case, and ultimately led to unusually stiff sentences for the threesome.
