What caused U.S. army veteran to go on shooting rampage?

CHICAGO, Aug. 6 (Xinhua) -- A disturbing portrait of the Wisconsin gunman continued to emerge on Monday, as law enforcement officials tried to find what caused the suspect to shot six people dead and three wounded at a Sikh temple.

The 40-year-old suspect, Wade Michael Page, a U.S. Army veteran and alleged former white supremacist, was shot dead by the police shortly after the Sunday shooting rampage in Oak Creek, Wisconsin.

While Oak Creek Police Chief John Edwards did not give a motive for the shooting, it is being treated as an act of "domestic terrorism."

Local media reports related to the gunmen published a painted picture of someone who was a skinhead or white supremacist and wore a tattoo of a 9/11 memorial on his arm. But criminal justice experts and forensic psychologists said it is too early to determine what caused the gunman to open fire.

"We don't want to blame this shooting on the economy or on veterans because we just don't know anything at this point," Louis B. Schlesinger, professor of forensic psychology at John Jay College of Criminal Justice of the City University of New York, told Xinhua.

"This doesn't happen a lot. We don't know what happened, but it's very infrequent. We do know that the Sikh people look different and that might have angered him because he could have thought they were Muslims. He didn't know that they are pacifists."
