Washington, DC (WVLT) - Doctors have amputated the hand of an East Tennessee man, who was injured following a Fourth of July fireworks show in Washington DC.

41-year old Bob Crapsey from Caryville worked for LaFollette based Pyro Shows.

Pyro Show President Landston Hill says that a large mortar shell failed to go off during the show, and instead, exploded about a half hour after the show ended, injuring Crapsey and another crew member.

Crapsey's wife says her husband suffered third degree burns on the broken arm.

He also has a broken leg and some minor burns on his chest and face.

The other worker suffered minor injuries.

Doctors say they were forced to amputate Crapsey’s hand because the muscle had become infected.
