Rory Dinsmore (d. 22 Oct 2012) was the son of Shelley and Alden Dinsmore, the younger brother of Ollie Dinsmore, and a resident of Chester's Mill, Maine. He was highly intelligent, regularly bringing home straight-A's. On Dome Day, he was present at the crash site on Route 119. The next day, he was instructed not to attend either Joe McClatchey's protest or Lester Coggins' prayer-group being held in the field of the Dinsmore Farm, and was given chores to do instead. After finishing his chores, it occurred to him to use his father's .30-.30 Winchester Elite XP3 to fire a hole through the Dome.
