Here you go, lots of info on the shooter. It sounds like he had a mental breakdown.

Colorado Springs gunman wrote rambling blog 2 days before shooting spree

Quote
The man who neighbors say shot three people in Colorado Springs on Saturday made a rambling post to a brand-new blog two days earlier that railed against his father, religion and government.

Noah Harpham, whose blog begins with the address where Saturday's shooting started, rages against a California mega-church pastor.

"Welcome to mind control," Harpham wrote.

In Colorado Springs, Harpham, 33, lived modestly in a series of apartments and worked in insurance.

On the online dating site eHarmony.com, Harpham described himself as a recovering alcoholic and a Christian.

The 6-foot-5 Harpham called himself "a big friendly giant."

Remember why, specifically, the Bill of Rights was written...remember its purpose. It was written to limit the power of government over the individual.

There is no believing a liar, even when he speaks the truth.
