OAK CREEK, Wisconsin -- Community members are coming together to seek emotional healing in the wake of Sunday's shooting spree that killed six people and wounded four at a religious service in a Milwaukee suburb.
For a third consecutive night, mourners and supporters will hold a vigil Tuesday, CNN affiliate WTMJ-TV reported, to remember the dead, pray for the wounded and grapple with grief and shock.
An Army veteran who neighbors say played in a far-right punk band was the lone gunman in the rampage at a Sikh temple in Oak Creek, Wisconsin, according to information Monday from law enforcement authorities.
Wade Michael Page, 40, was shot to death by police responding to the attack, the community's chief of police told reporters.
Hundreds attended a memorial for Page's victims at a Sikh center in the town of Brookfield Monday with the line of supporters overflowing outside the temple, WTMJ reported.
"This is one very large community," said Deanna Singh, who attended the service. "We're all one huge family."
"I think it's a sad day for all of us. It's horrific what happened," said Harbander Sithi.
A Methodist church in Oak Creek also held a candle light vigil Monday night to comfort victims' families and friends.
More than 200 attended, including members of Oak Creek's Sikh temple, the Milwaukee Journal Sentinel reported.
Sunday's attack in Oak Creek occurred 16 days after a gunman killed 12 people and wounded scores at a movie theater in Aurora, Colorado.
Oak Creek Mayor Stephen Scaffidi said Monday that he spoke with Aurora's mayor to get some advice on how to cope with the tragedy.
"He gave me some pointers and some suggestions on how to not only deal with the immediate but how we deal with the next few weeks," Scaffidi said, pointing out that the Colorado town was in its third week of coping.
"We're not going to let this define us; we'll never let it define us," Scaffidi said. "There are a lot of great people here, and we're not going to let this get in the way."
Worshipers at the temple in Brookfield, which is also a Milwaukee suburb, began fearing for their own safety on the morning of the shooting spree in Oak Creek, when they received calls from friends informing them of the tragedy, said one Sikh devotee.
"We really appreciate Brookfield police officers - that they did send squads, blocked the driveways, just in case," said Parvinder Singh Sangha, before entering Brookfield's gurdwara -- Sikh temple -- to participate in Monday's remembrance.
"If there is a shooter over there, is somebody else heading over here?" he explained the fears of the congregation.
Although the Sikh religion is not affiliated with Islam, Sikh men, who wear head coverings and let their beards grow, have been subject to Islamophobic hate crimes by perpetrators mistaking them for Muslims.
"We always feared this since 9-11, that someday this thing might happen. It did happen on a smaller level, but not on this level," President of Sikh Temple in Brookfield, Gurcharan Singh Grewal told CNN affiliate WITI.
Wisconsin's governor Scott Walker visited the Brookfield Sikh temple Monday to show support.
President Obama ordered U.S flags flown at half-staff through Friday "as a mark of respect for the victims of the senseless acts of violence."
The shootings in Oak Creek and in Aurora have heated up the debate on gun control as election campaigns are in full swing in the United States, and although both Obama and Republican challenger Mitt Romney have condemned the violence and expressed condolences to victims' families, tightening access to guns has remained a political hot potato.
New York Mayor Michael Bloomberg, a Republican and an outspoken proponent of gun control, has criticized Obama and Romney for not advocating tougher laws to prevent dangerous people from obtaining guns.
Bernard Zapor -- the Bureau of Alcohol, Tobacco, Firearms and Explosives special agent in the investigation -- said Monday that the 9mm semiautomatic handgun with multiple ammunition magazines used by the attacker had been legally purchased.
Page bought the gun on July 28 at the Shooters Shop in West Allis, Wisconsin, and picked it up two days later, according to a law enforcement official. The suspect bought ammunition there and used the shop's range at some point, said the official.
Sunday's attack occurred about 10:30 a.m., when temple members were reading scriptures and cooking food in preparation for the main Sunday service and community lunch. The temple has more than 350 members.
According to witnesses, the gunman started shooting in the parking lot, killing at least one person. He then entered the temple and continued firing, they said.
According to Oak Creek Police Chief John Edwards and the FBI, authorities have received tips that Page might have links to the white supremacist movement, but nothing had been confirmed. "I don't want to use that term (white supremacist) until we want to put it out there
