MILWAUKEE (AP) — The white supremacist who killed a half-dozen people at a Sikh temple in suburban Milwaukee acted alone, federal investigators said Tuesday.

Teresa Carlson, special-agent-in-charge of the FBI's Milwaukee office, issued a four-paragraph statement saying the agency had concluded its investigation into the Aug. 5 incident and found no evidence to suggest shooter Wade Michael Page had any help or was carrying out any directive from any white-supremacist group. Investigators also found nothing to suggest the attack was part of any ongoing threat to the Sikh community.

The statement did not mention any motive. Carlson previously said investigators may never know what drove Page.

"We did not talk about motive because of the fact it went with him," Milwaukee FBI spokesman Leonard Peace said in an interview. "That may never be known."

"We join the Sikh community in grieving the loss of their loved ones. We continue to work with temple leaders and all of our law enforcement partners in an effort to keep the community safe," Carlson said in the statement.

Page, a 40-year-old Army veteran, walked into the temple in Oak Creek shortly before Sunday services were set to begin and opened fire. He killed six people and wounded three. He also wounded the first police officer to respond to the scene.

The second officer to arrive got into a firefight with Page in the temple parking lot. The officer wounded Page, who fell to the ground and shot himself in the head before he could be captured.
