That one person can make a difference that the vast majority of people are wonderful and good. You don't hear about them -- the silent majority and we've caught almost 12100 fugitives because people had the guts to pick up the phone and say. I wanna help that victims get justice or that guy should be off the street seems like every day we come across another case that is so difficult to solve and you know we've been doing -- People's Court. Story Michelle Parker the missing mom now for several. Days and finally her ex fiancee named. As the prime -- -- -- this your first show absolutely we're gonna profile that -- now as you know today he's been named the prime suspect because he refuses to take a polygraph. I mean if you had nothing to do with the case you don't refused to take a polygraph they have twins together you say I'll do everything I can even -- -- in a little. Contentious relationship I didn't do everything to find the mother of our twins so. He's the number and we learned he had the habit of dropping or from the woods -- -- shoes on is the I I think his police work one on one I think they just waited until they had enough to say you're the guy and not now we've got -- finder and. The odds are that she's probably not alive and one place where they don't have enough evidence to hold the guy Gary Giordano down in -- in. Jail for more than a hundred days lot of circumstantial evidence but they didn't have the good. It's like to Natalee Holloway case all over again I mean look what happened was that -- and now he's in jail and in in Peru for murdering another girl. They never were able to indict beyond Vander -- because they couldn't find the body and I think this is the same case this is my own personal opinion this guy lured this woman down there. Took out an insurance policy honor. He's just lucky they haven't been able to find her body and they have to cut him loose because they don't have without a body there's no way they know they can't go they can hold on there's not enough evidence he was Smart enough not to leave any evidence in my mind there's no doubt. -- he probably killed this woman and he's gonna get away with it and the other what we've done we've spent a lot of time on this missing baby -- -- -- -- -- Kansas City and this one.
