the verizon center for customers with disabilities that's powerful. At 800-974-6006 tty/v. . Of today, an army soldier killed three people and injured many many more. Now identified as a married father Ivan Lopez. We just spoke to a neighbor who was there when Lopez's wife learned that her husband was the killer. We were outside talking about what was going on. I noticed his wife coming out of the apartment. She looked like she was strcrying. She looks distraught. I let her know everything was okay she need not worry. And she told me she hasn't talked to him since 3:00 and he was hysterical. She just sat out here and waited. She made a few phone calls to family and something. But other than that, I mean, it was really dramatic. Was she shaking? She was shaking, she was crying. Did she have her daughter with her? And her daughter was 3 years old? Yes. That same neighbor told us what she thought Ivan Lopez was like. He seemed like a pretty good guy. I didn't think anything strange or unusual. We're joined by peter whose retirement is focused on post traumatic stress in the military. I want to ask you specifically about this incident. I think a lot of people around the country are saying are we getting to a point where we have to protect our own soldiers at army bases. We have to be careful to characterize this as an individual who did ho home unable things. We don't know for sure. I know general milli indicated the possibility of post traumatic stress. But again, that's an initial assessment. We have to be careful to jump to any conclusions about this. Do you think it will lead to changes in security. When people hear this happens at an army base. It's time to have many of the soldiers there walking around with guns. I don't think we're going to see that. What concerns me in an incident like this is people are cob certained it was deployment spent in deployment in Iraq and they'll, in fact, brand everyone who's deployed as having some kind of a mental issue. The vast majority of our service members overseas come back and are perfectly fine. This particular service member was being treated for mental illness and diagnosed with PTSD. Do you think that problem, you say it may not be post traumatic stress? There's been a lot of research into post traumatic store stress. The problem is, this isn't like having a broken leg and going in and saying yes, your leg is broken. It's extremely difficult to diagnose with any accuracy. And that's not just true in the military. That's true in civilian life. What more do you think can be done to address the issue of mental ill rns in the military? Well, I think we need to address the issue of mental illness in society. I really believe that it is absolutely imperative that we put the necessary funds, and we get people to work together and share data and information, researchers, to try to get at these issues. That to me is what really should be done. This ought to be a wake-up call, not just for the military, but for all American society. To get at this problem. General, thank you for joining us. I really do appreciate it.
