Dr. Steve Pitt was brilliant. He was a forensic psychiatrist with an ability to see inside the criminal mind, and he regularly used his talents to help law enforcement across the country. He was also funny, thoughtful, and a great guy. And he was my friend. We met when I interviewed him for a Dateline story two years ago. I could tell we were going to become better friends as time went by. Except now Steve is dead, murdered outside his office in Phoenix.
