In addition to Murphy, three others who were at the temple were injured. Two are at Froedtert in critical condition. The third was treated and released, Edwards said.

In remarks before Edwards spoke, Mayor Steve Scaffidi said there is "no doubt in my mind the heroic actions of our police officers prevented a greater tragedy."

"The terrible event that we witnessed yesterday should not be a part of America," Santelle said at the news conference. "We are profoundly saddened by the events of yesterday and the work that has been done by this law enforcement community ... is a reflection of and is animated principally by our profound respect and our great sorrow about the losses the Sikh community has suffered in the past 24 hours. Our hearts are deep, our sadness is profound and we share with you great tears."

At the 10 a.m. news conference, authorities said they were attempting to identify another person, a white male, who they described as "a person of interest." But as of 2:45 p.m., FBI officials said they had identified the man and ruled him out as having anything to do with the temple incident.

The Southern Poverty Law Center, a group that has studied hate crimes for decades, reported Monday that Page was a frustrated neo-Nazi who had been the leader of a racist white-power band known as End Apathy.

Heidi Beirich, director of the center's intelligence project, said her group had been tracking Page since 2000, when he tried to purchase goods from the National Alliance, a well-known hate group.

The National Alliance was led by William Pierce, who was the author of "The Turner Diaries." The book depicts a violent revolution in the United States leading to an overthrow of the federal government and, ultimately, a race war. Parts of the book were found in Timothy McVeigh's getaway car after the bombing of the federal building in Oklahoma City in 1995.

Beirich said there was "no question" Page was an ardent follower and believer in the white supremacist movement. She said her center had evidence that he attended "hate events" around the country.

"He was involved in the scene," she said.

Pierce is dead, and Beirich said the National Alliance is no longer considered to be an influential group.

Also on Monday, a volunteer human-rights group called Responsible for Equality And Liberty, or R.E.A.L., found links between Page, his band and a white supremacist website called Stormfront.

Jeffrey Imm, who heads R.E.A.L., said in an interview Monday that someone based in Milwaukee using the name "End Apathy" began posting on the website in February 2008. Additionally, appearances by Page's band were promoted on the Stormfront site, including a white supremacist gathering in March 2012 in Richmond, Va.

Santelle, the U.S. Attorney for the Eastern District of Wisconsin, said he believed Page left the Army under a general discharge, but wasn't sure what that indicated about his service.

Officials at the Army's national records center in St. Louis said the FBI took Page's military records Sunday night.

Page has ties to Colorado and North Carolina, Santelle said, but investigators are not certain what brought him to the Milwaukee area.

It's unclear how long he was in Wisconsin before he began renting a duplex in the 3700 block of E. Holmes Ave. in Cudahy starting in July.
