MSM - Should be or think we know.
Here's Everything We Know About Temple Shooting Suspect Wade Michael Page
A couple bullet points but there's more at the link.
In 1994, Page was arrested for causing criminal damage to property between $20 and $200, according to BuzzFeed, which examined Texas court records. The crime, to which Page pleaded guilty, was a class B misdemeanor, BuzzFeed reported.
He was stationed at Ft. Bliss in Texas and at Ft. Bragg in North Carolina while originally being from Colorado. He was discharged from the Army for "patterns of misconduct," Reuters reported.
Page was never stationed overseas and in 1998 he was disciplined for being drunk on duty. That disciplinary action resulted in his rank being reduced from sergeant to specialist, according to Reuters. Page was not eligible to re-enlist, sources told Reuters.
The Southern Poverty Law Center, a group that has studied hate crimes for decades, reports that Page was "a frustrated neo-Nazi who had been the leader of a racist white-power band." They have a picture but we have not confirmed it. Here is End Apathy's MySpace page.
