This Dec. 28, 2015 photo released by Mexico’s Jalisco state prosecutor’s office shows who authorities identify as Ethan Couch, after he was taken into custody in Puerto Vallarta, Mexico. U.S. authorities said the Texas teenager serving probation for killing four people in a drunken-driving wreck after invoking an “affluenza” defense, was in custody in Mexico, weeks after he and his mother disappeared.
