'Affluenza' Mom Indicted For Helping Her Son Flee to Mexico

A Texas grand jury has indicted "affluenza" mom Tonya Couch on two charges related to her role in whisking her son to Mexico last year while he was on probation.

Couch was charged Thursday with money laundering, relating to cash she allegedly withdrew before crossing the border with her son, Ethan, CBS News reported.

She is also charged with hindering the apprehension of a felon, her son.

Ethan Couch was 16 when he caused a car crash that killed four people. His blood-alcohol level was three times the legal limit for adult drivers. Defense lawyers successfully argued the teen was so coddled by his wealthy parents he lacked responsibility for his actions.

An expert testified the condition was known as "affluenza."

He was ordered to serve probation in a sentence that was widely ridiculed as being far too lenient.

After video surfaced last year appearing to show Ethan violating his probation by playing beer pong, the teen and his mother fled to Mexico, authorities said. They were located in Puerto Vallarta after an FBI manhunt.

She was returned to Texas and placed under house arrest, authorities said. Ethan was transferred to adult court and ordered by a judge to serve nearly two years behind bars.
