Oak Creek, Wisconsin (CNN) -- At least seven people, including a gunman shot by a police officer, were killed Sunday in an attack on worshippers at a Sikh temple in the Milwaukee suburb of Oak Creek, police said.
The officer was wounded but "returned fire, and that shooter was put down," said Bradley Wentlandt, the police chief in nearby Greenfield, who briefed reporters. Investigators who picked through the building afterward found four bodies inside the temple and two other victims outside, plus the gunman, Wentlandt said.
At an afternoon news conference, Oak Creek Police Chief John Edwards said that authorities are treating the shooting as a "domestic terrorist-type incident," adding that the FBI will head the investigation.
Two semi-automatic handguns believed used by the shooter were recovered from the scene, a law enforcement source directly involved in the investigation told CNN.
