Deadly DUI Suspect Featured on CNN captured.
HARLOW: A man on the run from police for more than three years is profiled in CNN's original series "The Hunt" and now he is back in police custody. He was wanted in a deadly DUI crash that killed a young a young Florida man.</s>UNIDENTIFIED MALE: The driver of the Ford had hit wrong exit ramp coming the wrong way and collided head on with the Mustang.</s>UNIDENTIFIED MALE: I could hear the ambulances. I could hear a helicopter also. And I could see the lights from the ambulance. And the paramedics says to me, he didn't make it.</s>STEVE GASKINS, SERGEANT, FLORIDA HIGHWAY PATROL: We identified what became known as the wrong-way driver as Christopher Ponce and in a case like this that is so egregious it was very clear early on that alcohol most likely played a role.</s>HARLOW: Joining me now is John Walsh host of The Hunt. Christopher Ponce now captured after being in Spain for three years, who was he?</s>JOHN WALSH, HOST OF CNN'S "THE HUNT": Creep a little entitled coward creep. Who had 10 traffic violations, DUIs, speeding tickets, reckless driving. Not supposed to drive, gets in the family car, living at home, mom and dad taking care of him. Well to do family. Goes head on and kills a wonderful guy that gave up eight college scholarships to go back and work in the family business. With him in is British Afghan war vet and hurts him terribly. So a judge, I don't know why, but his toxicology report took about two weeks to do because he would not take a tox test. They took him to the emergency room, judge says, OK, I'll let him bond out $50,000, that's five grand. And he can sit home with his ankle bracelet on and watch TV and order Pizza. So then the toxicology report comes in, the judge recuses himself, I don't know why. But doesn't keep his word that this kid is going back to jail. So he's got 8 months to plan his escape. With I think police say that it may be his parents that aided him for three years. So I know the case, I'm a Florida guy, I know it's a horrible case in the news down there. Let's help this wonderful family. William Angel was a great kid, his father I talked to two days ago Wade Angel. I put myself in their shoes. I'm the father of a murdered son. So I say we are going to do this case. And we don't catch him, I think we're going to catch him right away. He's in Mexico or somewhere, have a great following in Mexico. So we keep airing it on CNN and HLN. We get a tip he might be in Spain. Somebody thinks they saw him. So the U.S. Marshals the best man hunters in the world saddle up. And Interpol, which are great friends of mine, they used today do some of the most wanted guys on "America's Most Wanted". They put Ponce on the red notice so the Spanish cops notice him in a bathroom in a bus stop, he's acting crazy and they nail him.</s>HARLOW: This Sunday, I've seen the episode, it is about a man that you call a full-blown, five-star sociopath.</s>WALSH: A horrible person. Alfonso Diaz Juarez, known as poncho. Comes back and forth. A Mexican national always been in sex trafficking, tries to get girls to come across the border illegally and work, says you are going to work as a maid at the Ritz Carton in Houston. You know we are the biggest offender of sex trafficking of children in the world. America is.</s>HARLOW: It is such an important topic.</s>WALSH: It is disgusting, this guy a rapist, brutalizes and brings girls, sells them in Houston, and he is on the top of my most wanted list. And hopefully Sunday he is going down.</s>HARLOW: It is important to watch, Sunday night with John Walsh. Thank you so much. You don't want to miss "The Hunt" this Sunday at 9:00 p.m. eastern, right here on CNN. Thank you so much for being with me.
