The AP has more details from the scene:
The gunman entered the Tennessee Valley Unitarian Universalist Church and fired three times with a shotgun, said church member Steve Drevick. He was called to the church immediately after the shooting to help out and later gave a statement to reporters.
Several people had head wounds, he said. Drevick had spoken to several eyewitnesses and said no one at the church recognized the gunman, who was tackled after he fired the shots, Drevick said. The gunman had more ammunition on him, Drevick said.

Police had cordoned off the church with yellow and red tape, and were taking statements and collecting video cameras from church members who'd been taping the performance. Police at the church would not immediately release any information and did not return phone calls from The Associated Press.
