Tens of thousands of residences and businesses in Moore County began the week without electricity after two electrical substations in the county were damaged by gunfire on Saturday evening. Federal, state and local authorities are investigating, and CNN reports that authorities recovered nearly two dozen shell casings from a high-powered rifle at the scenes. Authorities believe the person or persons who damaged the substations knew what they were doing, but have not identified a motive for their actions. The News and Observer reported on widespread speculation that the attacks were related to a drag queen show in Southern Pines that began just as the substations were damaged, but CNN reports that investigators have no evidence connecting those events. Duke Energy completed repairs Wednesday, and nearly everyone’s power had been restored by Thursday morning. A reward of up to $75,000 is being offered to anyone who provides information leading to an arrest and conviction.
