Two Puyallup men alleged to have attacked four Pierce County power substations over Christmas weekend will appear in U.S. District Court Tuesday. Matthew Greenwood, 32, and Jeremy Crahan, 40, were arrested Dec. 31, and face charges of conspiracy to damage energy facilities and possession of an unregistered firearm. Prosecutors will ask that both suspects remain detained at the Federal Detention Center at Sea-Tac pending future hearings. “I commend the work by the FBI to quickly identify these suspects and disrupt any future attacks on the east Pierce County power grid,” said U.S. Attorney Nick Brown. “We have seen attacks such as these increase in Western Washington and throughout the country and must treat each incident seriously. The outages on Christmas left thousands in the dark and cold and put some who need power for medical devices at extreme risk.” In the early hours of Christmas Day, two Tacoma Power utilities substations and one Puget Sound Energy (PSE) substation were attacked. Later that evening, another PSE substation was set on fire. Over 17,000 people lost power as a result of the attacks. The substations that were targeted include the Graham and Elk Plain substations operated by Tacoma Power and the Kapowsin and Hemlock substations operated by PSE.
