FORT WORTH, Texas: The mother of a fugitive teenager known for using an “affluenza” defense in a fatal drunken-driving wreck was released from a Texas jail, a day after a judge sharply reduced her $1 million bond for allegedly helping her son flee to Mexico.

Tonya Couch declined to speak with reporters when she was released from the Tarrant County Jail in Fort Worth. She posted the $75,000 bond and was ordered to wear an electronic ankle GPS monitor and remain at the home of another son, 29-year-old Steven McWilliams, except for appointments with her doctor and lawyer.

Her arrest affidavit alleges that she and her 18-year-old son, Ethan Couch, fled the state in December as Texas prosecutors investigated whether he had violated his probation in the 2013 wreck that killed four people. Both were taken into custody later that month in Puerto Vallarta, after a call for pizza delivery tipped off authorities to their whereabouts.

Tonya Couch is charged with hindering the apprehension of a felon and could face up to 10 years in prison if convicted. Ethan Couch is still being held in Mexico as he fights deportation.

During Ethan Couch’s trial, a defense witness said the teen was coddled into a sense of irresponsibility by his wealthy parents, a condition the expert called “affluenza.” The condition is not recognized as a medical diagnosis by the American Psychiatric Association, and its invocation drew widespread ridicule.

Law enforcement officials said Tonya Couch, 48, and her son fled the US after a video surfaced that appeared to show the teen at a party where people were drinking alcohol. If Ethan Couch was drinking, it would violate his probation and could lead to jail time.

According to an arrest warrant, Tonya Couch is accused of telling her estranged husband, Fred Couch, that he would never see her or his son again before fleeing.
