Flaherty was a member of Staff Sergeant Michael Daly's squad. On October 23rd, the squad was en route to West Stockbridge. Near Concord, the Vertibird carrying the squad was hit by the EMP, known as the Great Blackout, from the nuclear blasts that struck the Greater Boston area and crashed into the roof of the Museum of Freedom. The co-pilot died on impact, while the pilot died from his injuries a day later. The following day both he and Kanawa were shot and killed by panicked survivors.
Flaherty is mentioned only in Fallout 4.
