If you look at Begin -- like many family tragedies this one begins with young people and -- -- On March 31 a Thursday -- and some friends snuck into a downtown Denver nightclub with fake IDs. Kenya got flickered up. And then got separated from her cell phone and her friends. She went to the Constantine and keep them -- in the bathroom never came back yeah. By Friday afternoon -- friends and family started to search Kenya still hadn't come home. Or even called to check again that was really city -- higher -- -- friends bring her purse and cell phone back to her house and Tony's antenna goes up immediately. I noticed after a text messages. And it's -- this Travis and kindness from last night Donna white creepy fans in the past and she got home okay. Tony calls the number and leaves a message but Travis doesn't call back until Saturday. Has he -- but that doesn't sound very sure he sounds like he is just telling me what happen. The man's name is Travis for us he's a local entrepreneur or who makes gluten free granola bars and delivers them to customers in a white -- like this. He says he saw Kenya on the street that night. And tried to help her how does -- meet this guy the good samaritan Travis Ford says that she's. Of course parent from offers to give her house she willingly gets in his -- Security cameras near the nightclub would later confirm at least part of that story -- Kenya walking to a nearby hotel lobby at 1:30 AM Friday. Then wandering over to some nearby apartments and talking to a stranger Travis said he picked her up just after this the -- drive her home. As they're driving -- love you want to cigarette. He drives to this comical station and then some guy walks by smoking a cigarette. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- And then he went -- -- that he went home. Tony passes on that information to the police but he wants answers now. He calls Travis back and asks for the precise location of that Conoco station.

Tony already thinks Travis could be -- -- -- takes along a trusted friends. -- went on tomorrow. I'm element of this -- -- always went from the house. -- -- so scared she calls 911. Story arrives at the -- -- coach Travis is there -- -- to Denver police officers. My actual motive was about him make him what I needed to know. And that was -- -- Tony in the cops check out Travis is -- it's -- maybe to clean there was an overpowering smell of bleach. Coming from that the Dan had branded carpet in the back. And when the officer opened it he said that was just all ten in this old old -- this -- carpet. I reached out to shake his head and look in his eyes and I didn't. She apparently last person -- can lie. The police try to keep an open mind we explored all evidence yes it's possible that he was just trying to help and she didn't want office and I. That's right outside. But as detective -- girl lay and his team start investigating Travis -- story starts collapsing. For one thing that Conoco station was closed at that time of night. By taking -- to a close destination. -- it make sense to me. As they probe further to Travis Forbes past they learned that despite his wholesome granola image is something of a bad cookie. He's on probation for domestic violence and you get a few -- with the law. Thank you for calling at least -- days later the cops come here to the bakery where Travis Forbes has been renting space for his business.

If you just -- deliveries why would -- nude cart to. Bring in an empty cooler normally he would bring this -- wherein he would be empty it's a very light weight igloo cooler and why wouldn't be taped shut. Why would he take a close if it has granola bars and it. Who cares if it pops open and rising at a pop open. If that's not enough to make you go. Take a look at what happens next Forbes is seen with the old carpet in the back of the -- We rolls it up later on we find out that he burned. And to top it all off right here he's leaving out the back door and carrying a bottle of bleach some rags and -- looks at the springer. Remember that smelled Tony had noticed. Bleach kills DNA if he can destroy a lot of evidence finally Forbes heads to Monica's office and implements a surveillance video. All the spills quote. Altogether.
