The most extensive coverage is at the Denver Post. Talking Points Memo also has good coverage.
Holmes was a neuroscience student, who recently dropped out of graduate school at the University of Colorado. As usual with such people, he was a polite man who kept to himself.
I will venture the following speculations about what will be found when Holmes's background is investigated:
- It will turn out that Holmes had a history of violent fantasies, possibly even a history of actual violence, perhaps directed at animals
- He studied neuroscience in part because he was seeking a cure for his disorder, but it may also have given him the opportunity to cause pain.
- His problems were recognized. It is possible he sought help for them.
- The people who recognized his problems did not act on the knowledge, perhaps were unable to do so. If he sought help, he did not get it.
