You mentioned the prior Aurora church shooting. JSOnline also reported today another (older) 2005 church shooting in nearby (from Oak Creek) Brookfield, FYI:

“That would make for a different situation than the 2005 mass shooting at a service of the Living Church of God at the Sheraton hotel in Brookfield [27 miles from Oak Creek].  There, a church member, Terry Ratzmann, 44, opened fire during services, killing seven people and himself”:

BTW, the FBI now says Wade Page did not have a 911 tattoo (maybe it was one of the OTHER 4 guys!) :-/ James Holmes supposedly had a license plate that said ROC 911.

The FBI has taken Wade Page’s military records. I suppose that’s standard procedure(?):

“Officials at the Army’s national records center in St. Louis said the FBI took Page’s military records Sunday night”:

“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”:
