The matter was revealed when FBI Special Agent in Charge Teresa Carlson stated that the real motive of the shooter is yet to be defined on Sunday's shooting at the Sikh Temple of Wisconsin. The gunman identified as Wade Michael Page was reportedly shot down by officers.
The fact that Page was not involved in any crimes earlier and that he was not part of any investigation has baffled investigating authorities. Inputs from local sources say that he was never seen around the Gurudwara.
With the shooting incident indicative of a hate crime, the investigators are looking into the matter if Page was motivated by racist ideology that could lead police to accomplices. The Southern Poverty Law Centre, meanwhile, described Page as a "frustrated neo-Nazi" who participated in the white-power music scene, jamming in bands called Definite Hate and End Apathy.
The FBI on the other hand has termed the incident as domestic terrorism, a violent act for social or political gain. Page's girlfriend and nursing student Misty Cook was also arrested on a tentative charge of being a felon in possession of a firearm, South Milwaukee police said on Tuesday.
