 accessed Thomas Crooks' phone, but as of tonight, investigators say there's no indication that he suffered from any mental illness or had any political motivation. Crooks' neighbors say they're still shocked as he was a relatively quiet member of the community. The only thing that was odd was that he kept to himself. Like, he didn't talk to people much, which I found odd because I like to talk to people and I like to make conversation, but not everyone does. He kept to himself.
