(USA TODAY) - The FBI says Wade Michael Page, the gunman in Sunday's deadly shooting rampage at a Sikh temple in Wisconsin, died of a self-inflicted gun wound after being hit by police.
FBI special agent Teresa Carlson tells reporters in Milwaukee today that the 41-year-old gunman shot himself in the head after the second police officer responding to the scene shot him in the stomach.
Page killed six people in the Sikh temple in Oak Creek, a Milwaukee suburb, on Sunday.
Carlson says investigators have not yet "clearly defined a motive" for the killings.
Page had been active in white supremacist groups, police say.
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.
