A 32-year-old Puyallup man pleaded guilty in U.S. District Court Friday to conspiracy to destroy energy facilities in relation to the vandalism of four substations on Dec. 25 that left about 30,000 without power and caused $3 million in damages. In a plea agreement, Matthew Greenwood admitted that he and Jeremy Crahan, 40, vandalized four power substations and plotted to fell trees to take out power lines. Greenwood faces up to 20 years in prison when he is sentenced on July 21.
