A 60-year-old man was killed and eight others wounded Sunday after a gunman entered a church in Knoxville, Tennessee, and opened fire with a shotgun, police said.
Knoxville Police Chief Sterling Owen told Fox News that the killed man was an usher at the church and the killer is now in custody.
None of those injured were children and a hospital spokeswoman says five of the wounded are in critical condition.
A church member who arrived moments after the shooting says the gunman opened fire as congregates watched a youth performance.
There were about 200 people in the church at the time and they were watching a youth performance being put on by 25 children.
The Tennessee Valley Unitarian Universalist Church said in its website that it is a place for people to "worship and work together for social change."
Since the 1950s, the church has worked for desegregation, racial harmony, fair wages and women's rights and gay rights.
It also has provided sanctuary for political refugees and fed the homeless.
The relationship between the gunman and the church was not immediately known.
