'Affluenza' teen Ethan Couch detained in Mexico
Couch, 18, went missing earlier this month, two years after he made national news when he was sentenced to probation for a drunken driving crash that killed four people.
Couch is expected to be turned over to the U.S. Marshals Service, who have spent weeks searching for him. A spokesman for the service declined to comment.
He is wanted by authorities in Tarrant County, Texas, for allegedly violating probation. His mother was listed by Texas authorities as a missing person after her son's disappearance, and the authorities said they believed she was assisting her son.
