After that, the roommate makes me think of my old roommate. She was anorexic and super high achiever and had no life outside of school and work. She was also Asbergers/borderline autistic. And the roomie said his interviews were just like how he always acts, doesn't show much emotion ever. I worked with autistic kids for my MA. He seems to have many qualities: no emotion, hard worker/high achiever, not many friends etc. Edit: Anyway a lot of us are on the spectrum in some way, doesn't mean that has anything to do with murder, more his personal relationships.
