On one of the news reports on the murders (about a week ago), they showed this guy riding his segway around the neighborhood. At one point, he stopped and gave them an interview. He did not come across as guilty, but there was something about him, such hubris, that I instantly did not like him. That rarely happens with me. He just set off alarm bells.
You are exactly right...he exhibited the same cockiness that cop that killed his ex-wives did. Thought he was too smart for the legal system. Delusions of grandeur on display if you ask me.
