* Police identify shooter as Wade Michael Page
* Page served in the military from 1992 to 1998
* Gunman had links to neo-Nazi group, was in skinhead band
Police identified the gunman who killed six people at a Wisconsin Sikh temple as a 40-year-old U.S. Army veteran, and a monitor of extremists said he was a member of a racist skinhead band.
Oak Creek Police Chief John Edwards told a news conference on Monday that the gunman, who was shot dead by police at the scene on Sunday, was named Wade Michael Page, a former U.S soldier who served from 1992 to 1998.
The gunman shot dead six people and seriously wounded three, including a police officer, at the Sikh Temple of Wisconsin as worshippers prepared for religious services.
The victims were five men and one woman, aged between 39 and 84.
Authorities said they were treating the attack as an act of domestic terrorism. American Sikhs said they have often been singled out for harassment, and occasionally violent assault, since the Sept. 11, 2001, attacks because they are mistaken as Muslims due to their colorful turbans and beards.
U.S. military sources said Page had been discharged from the Army in 1998 for "patterns of misconduct" and had been cited for being drunk on duty.
Page had served in the military for six years but was never posted overseas. He was a psychological operations specialist and missile repairman who was last stationed at Fort Bragg, North Carolina, the sources said.
In June 1998 he was disciplined for being drunk on duty and had his rank reduced to specialist from sergeant. He was not eligible to re-enlist.
Page had been a member of the racist skinhead band End Apathy, based in Fayetteville, North Carolina, in 2010, said Heidi Beirich, director of the intelligence project at the Southern Poverty Law Center (SPLC) in Montgomery, Alabama.
He also tried to buy goods from the National Alliance, a neo-Nazi group, in 2000, she said. The SPLC describes the National Alliance on its website as "perhaps the most dangerous and best organized neo-Nazi formation in America."
WANTED TO 'MOVE FORWARD'
In a 2010 online interview with End Apathy's record label Label56, Page said he had founded the band in 2005 because "I realized ... that if we could figure out how to end people's apathetic ways, it would be the start towards moving forward."
Police searched an apartment at a duplex in the Cudahy neighborhood near Milwaukee, presumed to be the residence of the gunman. Generators and floodlights were set up along the street and a bomb squad was on the scene.
Members of the Sikh community said the president of the congregation and a priest were among the victims.
Describing how the events unfolded, Chief Edwards told reporters the first officer on the scene found a victim in the temple parking lot and went to render assistance. The officer was then shot eight or nine times at very close range with a handgun, Edwards said.
The gunman then fired on a police car, ignoring officers' commands to drop his weapon, and was shot and killed by police.
The wounded officer was being treated in a hospital, Edwards said.
Bernard Zapor, special agent in charge for the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives, said the weapon used in the shooting was a 9mm hand gun that had been legally purchased.
Wisconsin has some of the most permissive gun laws in the country. It passed a law in 2011 allowing citizens to carry a concealed weapon.
A search of a nationwide public data base showed that Page had lived at some 20 addresses in Wisconsin, North Carolina, Colorado, California and Texas.
Jagjit Singh Kaleka, the brother of the president of the temple who was among the six Sikhs killed, said he had no idea what the motive was for the attack.
The shooting was yet another in a too-frequent series of U.S. mass killings, coming just over two weeks after a gunman killed 12 people at a theater in Aurora, Colorado, where they were watching a screening of new Batman movie "The Dark Knight Rises."
The Sept. 11 attacks were carried out by Muslims linked to the al Qaeda militant group led by Osama bin Laden. Sikhs are not Muslim, but many Americans do not know the difference, members of the Sikh community said.
There are 500,000 or more Sikhs in the United States but the community in Wisconsin is small, about 2,500 to 3,000 families, said local Sikhs. The temple in Oak Creek was founded in October 1997 and has a congregation of 350 to 400 people.
The Sikh faith is the fifth-largest in the world, with more than 30 million followers. It includes belief in one God and that the goal of life is to lead an exemplary existence.
