The Tennessee Wildlife Resources Agency says a woman was killed and a man was injured when a house boat exploded on a river. The agency says the explosion happened shortly after the 38-foot vessel refueled near the Montgomery County Conservation Club along the Cumberland River on Sunday afternoon. Officials say the operator, a 56-year-old man, and the passenger, a 54-year-old woman, were thrown into the water by the explosion and the two were rescued by a nearby boater. Authorities say they were taken to a hospital where the woman later died from her injuries. Authorities are continuing to investigate the explosion.
