The perpetrator, James Eagan Holmes, was a shy and quiet white guy and a neuroscience graduate student. A female classmate told NBC News:
"I always thought that he was a little strange. I could never put my finger on it, but something told me to not get to close to him, female instincts I guess," the female student told NBC News. "I had tons of classes with him and lived across from him in the Honors dorms. He was a very smart guy though. He was a little bit of a weird guy, but we were honors students, so weird people were kind of common."
So she avoided him because he was “a little strange,” but she hinted that she felt the same way about a lot of the male honors students. I guess a guy like him can't get a girlfriend.
This is a classic case of beta-male rage.
