OAK CREEK, Wis. (CNN) - An Army veteran who neighbors say played in a far right punk band was the lone shooter in the rampage at a Sikh temple in Wisconsin that killed six people and wounded four, according to information from law enforcement authorities.
Wade Michael Page, 40, was shot to death by police responding to the Sunday morning attack in the Milwaukee suburb of Oak Creek, the community's chief of police told reporters Monday.
It was the latest violence against the Sikh community in the United States in apparent misdirected revenge for the September 11, 2001 terrorist attacks.
The attacker shot people inside and outside the temple, including a police officer. Oak Creek Police Chief John Edwards said. Another police officer with a rifle then shot the gunman, who died at the scene.
According to Edwards, police have received information that the suspect "may have been involved in" the white supremacist movement, but he added it remains unconfirmed.
Two neighbors of Page identified him in photos that showed him playing in the far-right punk band "End Apathy," and the nephew of the slain president of the Sikh temple said the attacker had a 9/11 tattoo on his arm.
Teresa Carlson, the FBI special agent in charge of the investigation of Sunday's shooting, said no motive for the attack has been established. The FBI was looking into whether it was domestic terrorism, which is the use of violence for political or social gain, Carlson said.
"We are looking at ties to white supremacist groups," Carlson told a news conference, adding there was no active investigation of Page prior to Sunday's attack.
Because of their customary beards and turbans, Sikh men are often confused with Muslims, and they have been the targets of hate crimes since the September 11, 2001, attacks on New York and Washington.
Sikh victims killed in the assault ranged in age from 39 to 84, according to a list provided at the news conference.
Two other Sikh victims remained hospitalized in critical condition, while a third was treated and released, Edwards said.
The wounded police officer, identified as 51-year-old Lt. Brian Murphy, also was in critical condition, the police chief said. Edwards earlier said Murphy's injuries did not appear to be life-threatening.
Page, born on Veterans Day in 1971, joined the Army in 1992 and left the service in 1998, said information from Army Spokesman George Wright. While he had "patterns of misconduct" during his service, according to a Pentagon official, he received an honorable discharge.
Bernard Zapor, the Bureau of Alcohol, Tobacco, Firearms and Explosives special agent in the investigation, said Monday that the 9 mm semiautomatic handgun with multiple ammunition magazines used by the attacker had been legally purchased.
Edwards said the attacker shot people inside and outside the temple, including a police officer, before another police officer shot him.
"They gave the individual commands. He didn't respond to those," Edwards said "He shot some of the squads, damaging them, and he was at that time shot at by one of our officers with a rifle."
Asked about the officer shot in the attack, Edwards said that "it was very close range."
"He was tending to someone down in a crouch position, what it appears," the police chief said. "And the individual walked up on him, around a vehicle and engaged him very closely - inches to feet, and fired at him. He was shot between eight and nine times."
The suspect had a criminal record, Edwards said. A background check showed Page had separate convictions for DUI in Colorado in 1999 and for criminal mischief in Texas in 1994.
One of the dead was a priest named Prakash Singh, who recently immigrated to the United States with his wife and two young children, said Justice Singh Khalsa, a temple member since the 1990s.
Relatives of Satwant Kaleka, the president of the temple in Oak Creek, Wisconsin, said Monday that he was killed fighting the attacker.
"From what we understand, he basically fought to the very end and suffered gunshot wounds while trying to take down the gunman," said Kanwardeep Singh Kaleka, his nephew.
"He was a protector of his own people, just an incredible individual who showed his love and passion for our people, our faith, to the end," he said, near tears. "He was definitely one of the most dedicated individuals I have ever seen, one of the happiest people in the world."
Kaleka said those inside the gurdwara, or Sikh house of worship, described the attacker as a bald white man, dressed in a white T-shirt and black pants and with the 9/11 tattoo on one arm -- which "implies to me that there's some level of hate crime there."
While officials try to piece together what prompted the man to go on his shooting spree shortly before the main Sunday morning service, America's Sikh community struggled to come to grips Monday with the brutal attack.
Kaleka was horrified to have such violence occur at his place of worship, especially just two weeks after the 12 killings
