A man wielding a shotgun entered a church and opened fire, killing one person and injuring eight others, police said. The gunman was tackled by church members and eventually taken into police custody. None of the children were injured. A hospital spokeswoman said five of the wounded were in critical condition. Knoxville Police Chief Sterling Owen identified the man killed as Greg McKendry, 60, a longtime church member and usher at the Tennessee Valley Unitarian Universalist Church. "It appears Mr. McKendry was the first person he (the gunman) encountered when he walked into the sanctuary," Owen said. "It's going to be a while before all the facts are cleared up."
