According to KCTV in Kansas City, local resident Ronald Long was installing a satellite TV dish when he ran into a snag trying to drill a hole through the house's exterior for the cable. After several frustrated attempts, Long had the bright idea to let his pistol do the work for him.

Unfortunately, standing outside was his wife, Patsy. The bullet struck her in the chest, and she died shortly thereafter.
