James Holmes sat in court on Monday, with his eyes drooping and showing little emotion.
Many people question why, since he's the suspect of killing 12 people in a Colorado movie theater.
Clinical psychologist Ronda Weber says she's seen similar situations in court, and she says this behavior can be a defense mechanism.
"They're not seeing themselves in a way that everyone else is looking at it, so at some level he was looking at himself as being a victim and he was in some way protecting himself in a strange way," said Weber.
Many still question how anyone could commit such a crime.
Weber says the suspect must have a personality disorder.
"So there definitely were significant difficulties in his sense of self, and so this was a way for him to feel significant obviously in a very pathological, very sick way," said Weber.
Weber says a small percentage of people can snap like this, if they don't have close relationships.
"If you have close relationships, people would say 'hey you're getting weird now' and look out for you and they would take the time to make sure you're okay if you're getting a little unbalanced and would say 'you need to get some help," said Weber.
Having close relationships is something Weber advises we all do after this tragedy. She says the mass shooting has indirectly affected all of us.
"Going to the movies is normally a pleasant past time to relieve stress, and now everybody that goes to the movies has in the back of their minds, you know, what could potentially happen," said Weber.
She says it's important for us to stay close with our family and friends. That way we can ask for help when we notice something strange. She says that's how we can prevent more situations like this from happening again.
