Transcript for 'Affluenza' Teen's Mom Tonya Couch Arrives Back in US
Now to breaking news in the so-called affluenza teen. Ethan couch, his mother Tonya back on American soil arriving in Los Angeles just hours ago. ABC's Matt Gutman has the latest from Guadalajara, Mexico. Reporter: Good morning, Amy. A very stone-faced looking Tonya couch didn't answer reporters' questions. Her son Ethan bundled out of that facility and taken to Mexico City. It was another legal reprieve for the affluenza teen whose lawyers helped him avoid a single day in prison after he pled guilty to killing four people in that drunk driving crash. Just hours ago Tonya couch hauled back to the U.S. Grim-faced as U.S. Marshals escorted her in handcuffs through Los Angeles international airport. She faces a possible two to ten year sentence for hindering the apprehension of 18-year-old son Ethan. ABC news spotted Ethan in Guadalajara, Mexico, escorted into this van at this immigration detention center. The van speeding out of the garage. We believe Ethan couch is in that van that just rushed out of here. We saw him moments ago being moved from one side of this detention center to the other side. And Mexican authorities confirming overnight to ABC news he was sent to Mexico City, his third city since his arrest Monday. Mexican authorities say he'll be held until the end of these immigration proceedings. But his first two nights in a Mexican detention center spent behind those locked Gates. So you've been inside. What's it like? We got two holding cells to hold detainees until they figure out the situation. Reporter: Tonya couch's lawyer speaking out for the first time. Put yourself in Tonya's shoes. What would you do if you were a parent with a son who is the most hated boy in America. What would you do to protect him? Reporter: Texas authorities called it something else, hindering the apprehension of a fugitive. With the couches now in custody we're learning more about their time as fugitives here in Mexico. In this exclusive video you can see Tonya couch saunter into this butcher shop trying to pay in dollars. And Ethan just two hours before his capture seemingly at ease in his life as a fugitive. With the backwards hat and freshly dyed jet black hair. Thank you, my friend. Reporter: For people who tried very hard to avoid lockup in a U.S. Jail the couches will spend a lot of time in detention. Tonya couch will probably be in a U.S. Marshals facility until Saturday or Sunday and Ethan could spend weeks here as his immigration process plays out. Amy. All right, Matt Gutman with the latest and you can find out much more about the Ethan couch tomorrow on a special "20/20," end of the road, right here on ABC.
