Regarding the two Shootings in Colorado

Currents reports are suggestive that Matthew Murray was influenced by psychiatric medication, as is too common this day in many public shootings:

At Abeyta's side was Peter Warren, the school's director. Warren said that when Murray came to the school early Sunday asking to stay the night, staff members did not recognize him.After Murray was identified by police, the school realized he had attended its training program in 2002. The Arvada school is a branch of an international missionary program that trains thousands annually.

Warren said school officials refused to assign Murray to a mission because of an unspecified health problem that could make such work unsafe. Warren would not elaborate, and he and Abeyta left without taking questions.

But this is not nearly enough evidence to say it was so, despite the odds in favor of such a conclusion. And to be fair, a person can be on unbalanced mind for reasons not having to do with psychiatric drugs. Uncommon, but it happens.

In court papers, police said Murray had written threatening letters to the school and spent many hours a day on the Internet as a computer student, the Gazette of Colorado Springs reported. [...] It also was unclear why Murray traveled the roughly 75 miles from the missionary school in Arvada to New Life Church, which has a Youth With a Mission branch office. New Life achieved notoriety last year when its founder, Ted Haggard, was accused by a former gay prostitute of trading drugs and sex.

Information is unclear at this time, and we await further reports.
