Shockley was one of the mercenaries working for Colonel Stuart in his operation to free dictator General Ramon Esperanza from custody by taking over the instruments of Dulles International Airport's control tower.
Die Hard 2[]
Shockley was alongside O'Reilly, Sheldon and Mulkey at the airport annex skywalk which is under construction, making sure the antenna array gets blown up without interruptions. Then chief engineer Leslie Barnes and five Airport SWAT officers arrived, as they expected and they sprang their ambush. Shockley was under fire from his original spot and moved into an another spot. Just as he opened fire, a SWAT officer kills Shockley, by shooting him multiple times in the chest, with a M16A1 assault rifle.
Shockley's death
Shockley was the second mercenary killed during Stuart's operation, making him the only mercenary that John McClane didn't kill in the movie.
