 Coy kept the Springfield rifle in the gallery and lowered an M1911 pistol, keys, a number of clubs, and gas grenades to his accomplices below.Continuing along the gun gallery, Coy then entered D Block, which was separated from the main cellhouse by a concrete wall and was used for prisoners kept in isolation.There, he used the rifle to force officer Cecil Corwin to open the door to the main cellhouse and let the others in.
