Wisconsin Sikh temple shooter Wade Michael Page died of a self-inflicted gunshot to the head after he was shot and wounded by police, the FBI announced at a news conference today. An FBI special agent added that investigators have interviewed more than 100 people, combed through Page's email, and recovered evidence from the scene—139 items were taken from the temple's parking lot alone. But they have not yet "clearly defined a motive" for the Sunday shooting that left six worshipers dead.
Detectives have warned they might never learn for certain what drove him to attack total strangers in a holy place. The special agent noted that investigators have not found any kind of note left by Page. "We have not identified anyone else responsible for the shooting," she added.
