The investigation continues after an explosion killed one man and injured two others in Lincoln County.
Retired state trooper Shannon Corman was killed. As of Wednesday night, his wife, Louise Corman, was listed in serious condition at UK Hospital. Another man, Frank Greenwood, is in critical condition. Greenwood's family says he has burns over 90 percent of his body.
Shannon Corman was a licensed weapons dealer. Investigators think it's possible he was mishandling black powder, and had it too close to several heating sources. Investigators think that may have played a role in the explosion.
The investigation is ongoing.
