U.S. officials have charged the mother of a young man. It is said that Tonya Couch and her son, Ethan fled to Mexico in November. Ethan Couch was wanted by U.S. officials for violating his punishment, in connection with a drunk-driving crash that killed four people two years ago.
    That crash happened when Couch was 16 years old and drunk. He crashed into a car that was on the side of the road. He was found guilty and sentenced to 10 years under observation.
    Mexico drove out the mother of the young man on Wednesday. She is charged with violating the punishment of her son. In other words, she is charged with helping her son flee to Mexico. If convicted, she could face between two and 10 years in jail.
    The mother and son were arrested on Monday in Puerto Vallarta on Mexico’s west coast. U.S. officials located the two when Ethan Couch used one of their phones to order pizza.
    It could be weeks before Ethan Couch is sent back to the United States.
