(USA TODAY) - The FBI says Wade Michael Page, the gunman who killed six people in a rampage at a Sikh temple in Wisconsin on Sunday, died of a self-inflicted gun wound after being hit in the stomach by police.
FBI special agent Teresa Carlson tells reporters today that investigators have not yet "clearly defined a motive" for the killings in the Milwaukee suburb of Oak Creek.
Page, 40, had been active in white supremacist groups, police say.
Carlson says the gunman shot himself in the head after the second police officer responding to the scene shot him in the stomach.
She says she can't say if the police bullet, which came a very short time before he turned his gun on himself, would have been fatal.
"I've seen the video," Carlson says. "It's an amazing shot."
Lt. Brian Murphy, who was among three people wounded in the attack, is up and walking, says Police Chief John Edwards.
Police in South Milwaukee have arrested Page's ex-girlfriend, Misty Cook, on an unrelated weapons charge, but say they do not believe she was linked to the attack on the Sikh temple.
