Transcript for Michigan Freeway Shooter: Why Did Suspect Do It?
For more on the why, we're joined from washington, by chief psychologist for the secret service, dr. Rendazo. You say it's key what he told his mother. If anything happens to me, the government may be involved. You say that kind of paranoia could be a clue to what was motivating him? Absolutely. There's so much we don't know about this case yet. And we're going to be learning as the investigation unfolds. But we've got two big clues here, with what the mother and what his aunt shared with newspapers about the paranoia, about the sense that if anything happens to me, the government is to blame. This suggests he may have been experiencing what we call a break with reality, which may indicate some developing mental disorder, like a psychosis. Most people that develop these delusions do so in their TEENS OR EARLY 20s. But severe life stress can cause somebody later in life, like THIS MAN, IN HIS EARLY0s, TO Also develop delusis? Absolutely it can. I want to emphasize first, most don't engage in violence. But people may have a propensity, or a family history to this disease, under severe stress. Dire financial conditions, loss of multiple jobs. Can develop this break from reality. His wife tried to get him help from a doctor, but he refused. How difficult it can be to make an adult seek help they clearly might need. This is so true. What's critical is what people often don't know is law enforcement or the criminal justice system can play a key role in getting someone like this into treatment and back on track. These are largely treatable conditions. All right. Unfortunately, after you've gone on a crime spree like this, justice will prevail. All right. Dr. Randazzo, thanks for being with us this morning. We'll have more on this case as it develops.
