UPDATE: Authorities have released the name of the shooter, a 40-year-old man. Reuters is reporting he was discharged from the Army in 1998 for misconduct.
And more from the Milwaukee paper, with strong assertion that he was white supremacist:
He served in the Army for several years and was assigned to psychological operations, or PsyOps, according to the sources.
He is no longer in the Army.
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 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.
