Wade Michael Page acted alone when he fatally shot six worshippers and injured four others in his rampage at the Sikh Temple of Wisconsin in Oak Creek on Aug. 5, the FBI said Tuesday.
In its statement, the FBI said it found no evidence to suggest the attack was "directed or facilitated by any white supremacist group." The FBI and Justice Department initially had said they were looking into Page's killing spree as an act of domestic terrorism.
Teresa L. Carlson, special agent in charge of the FBI's Milwaukee office, said the investigation was now officially over.
"During the shooting at the temple, Page exchanged gunfire with two Oak Creek police officers, seriously wounding one, before being shot by another officer, then turning his weapon on himself. There is also no evidence to suggest the attack was part of any ongoing threat to the Sikh community," the FBI statement says.
Page shot Oak Creek police Lt. Brian Murphy multiple times. His fellow officer, Sam Lenda, a decorated sharpshooter, shot Page. Page then put his 9mm handgun to his head and fired what would be the fatal shot.
"We join the Sikh community in grieving the loss of their loves ones," Carlson said. "We continue to work with temple leaders and all of our law enforcement partners in an effort to keep the community safe."
Carlson said the FBI generated 200 investigative leads, interviewed 300 people and collected more than 200 pieces of evidence.
Since the shootings, members of the Sikh community have lobbied Congress to require the FBI to track hate crimes against Sikhs.
Amardeep Kaleka's father, temple President Satwant Singh Kaleka, was killed trying to stop Wade. Amardeep Kaleka said Tuesday that his faith community largely was satisfied with the results of the investigation, though he conceded no one ever will really know why Page went on his rampage.
"Our chief focus now is that we are interested in what we can do as a nation to stop this from ever happening again," he said.
Members of the Sikh community had been briefed in advance of the FBI's report.
Page had moved to Milwaukee in late 2011, perhaps for a girlfriend who might have shared his white-power beliefs. But Page and Misty Cook broke up weeks before the shooting.
Page's strong beliefs in the white power movement had led to speculation that an organized group of white supremacists had been involved in the temple shootings. But the FBI report concludes that there was no evidence to make that connection.
