Let's bring in former consultant and special agent at the fbi, brad garrett, in washington, d.C. This morning. I know the first calls came to whitn whitney's home around 7:00 a.M. It took her husband nearly three hours to call 911. Is that timeframe troubling to you? A little bit. You have to look at when an adult goes missing, what in their life could have caused it. Look at the husband. What was his relationship with whitney? Were there issues? Did he have any reason to harm her? And you look at her life. If you eliminate both of those, you wonder, why did he wait? I don't know. He's calling on the phone. He's left apparently, a number of voicemails. He sent a number of texts. He doesn't get an answer. But that is a block, if I were investigating this case, I would fill in. We should point out the husband is cooperating fully with police. And there could be a huge treasure trove of evidence with the discovery of this suv. Lots of dna, fingerprints inside and outside that car. That's exactly right. And the thought that the glass from her -- the driver's side window is possibly in the parking lot at the apartment complex suggests to me that she may have interrupted someone stealing her car, panicked. They grabbed her. And it sup the idea that they went to a number of gas stations. They purchased a small quantity of gas and moved on. It's not planned. We don't know what we're going to do now. We were going to steal a car. And now, we have a live person with us. Finally, the car was left in a walmart parking lot. Lots of cameras in those walmart parking lots. Walmart is great with surveillance cameras. So, the idea they might have a shot of someone dropping that car, could be a great lead. All right. Brad garrett, thank you so much. We'll be staying on top of this search and this investigation.
