Ethan Couch's mother arrived in the United States on Thursday after her deportation from Mexico. Tonya Couch was transported through Los Angeles International Airport in the custody of U.S. Marshals. It was not immediately clear why she was taken to L.A. instead of Texas, where she lives and her son is wanted for violating probation for a 2013 drunk driving crash. Couch's son is still in Mexico and was moved to an immigration facility after a judge issued a temporary injunction blocking his deportation back to the U.S.
