A Mexican official says the mother of young U.S. fugitive Ethan Couch has been deported to the United States.

The National Immigration Institute official says Tonya Couch left late Wednesday afternoon on a flight from Guadalajara, Mexico, to Los Angeles. The person was not authorized to discuss the case and revealed the information on condition of anonymity.

The official says she was sent home because immigration authorities did not receive a judge’s injunction like the one that temporarily blocked the deportation of her son. For now he will remain in custody in Guadalajara.

Authorities say the 18-year-old Couch, who used “affluenza” as a defense in a fatal drunken-driving wreck in Texas in 2013, fled with his mother to Puerto Vallarta, Mexico, as prosecutors investigated whether he had violated his probation. Both were detained Monday.
