DALLAS (AP) — A Mexican official says a Texas teenager on probation for killing four people in a drunken-driving wreck and invoking an "affluenza" defense who was found in Mexico along with his mother will be returned to the United States on Tuesday.


Ricardo Ariel Vera, the representative of Mexico's immigration institute in the western state of Jalisco, said the mother and son were being held at immigration offices in the state capital, Guadalajara, and would be returned to the United States aboard a commercial flight to Houston sometime Tuesday.

18-year-old Ethan Couch and his mother were located and detained Monday evening in the Pacific Coast resort city of Puerto Vallarta.

Authorities in Texas say it appears the two planned their disappearance and even held something of a going-away party.

During the sentencing phase of Couch's trial, a defense expert argued that Couch's wealthy parents coddled him into a sense of irresponsibility — a condition the expert termed "affluenza." The condition is not recognized as a medical diagnosis by the American Psychiatric Association.
