Incident Summary:

5/30/1989: Two members of the Evan Mecham Eco-Terrorist International Conspiracy group, Mark Leslie Davis and Marc Andre Baker, were arrested as they attempted to cut through a metal support tower which held electric lines delivering electricity to the Harcuvar Substation near Wenden, Arizona in the United States. The two were trying to cut down the power line using a propane torch, similar to their previous incidents of terrorism in 1987 and 1988 at the Flagstaff, Arizona ski lifts and the power lines at the Grand Canyon, Arizona. The power pole was owned by the U.S. Department of Energy, and the Harcuvar Substation owned by the Central Arizona Project (CAP), which was the main source of water supply for Arizona. The perpetrators were arrested as they were at the location, about to carry out the attack, and thus, authorities believe much potential damage to the substation was prevented.
