VELEZ-MITCHELL: Cops say 34-year-old Jonathan Nall held a gun to his head and threatened to commit suicide at a Louisiana gas station. After two grueling hours, these officers -- and I applaud them for their courage -- were able to take Jonathan into protective custody. But his stunning girlfriend is nowhere to be found. And obviously that is a crisis.
26-year-old Melinda Denny, seen here in Facebook photos, last seen early Saturday morning. She was with this boyfriend who had a meltdown at the time. Fast forward ten hours later. Jonathan is alone, threatening to kill himself. What happened during the time they were last seen and the time that this meltdown occurred?
Straight out to the "Lion`s Den". I want to go to Marc Klaas, founder of Klaas Kids Foundation. And I hope you can use some of the skills that you have in locating missing children to give us insight into what may have happened to this young woman.
He has a gun, the boyfriend. His mother tells our affiliate that he`s bipolar and hadn`t been able to get treatment. We see in the cellphone video he`s ranting about the U.S. government. Others said he was ranting about aliens also being part of the problem. Here he is. This is a very dangerous set of circumstances, Marc.
KLAAS: Well, sure, it is. I mean this is a man with a very serious mental illness, who is not getting treatment, does not have his medications. And therefore, can easily move into a propensity for violence. He`s going to have to be contained somehow and brought back into coherence before they`ll be able to find this girl.
Now that having been said, the authorities in Louisiana are taking this very, very seriously. And the sheriff`s search and rescue teams are out there diligently looking for this young girl. But I`m afraid he holds the key and they need to bring him back to get to the truth.
