Couch's attorneys argued his wealthy upbringing made it impossible for him to understand the consequences of his actions, dubbing it "affluenza." A juvenile court sentenced him to 10 years of probation.
Couch's probation was revoked in 2016 after he attended a party where alcohol was served.
A Texas judge revoked bond for his 50-year-old mother. State District Judge Wayne Salvant had warned Tonya Couch last June to "use common sense" pending her trial on hindering apprehension of a felon and money laundering charges. She was charged after she and Ethan Couch fled to Mexico in 2015.

"I think he has made clear to me that he needed time behind bars -- just really get him to the place of ownership," the chaplain said.
Ethan Couch is now on probation until 2026. He is under a mandatory curfew and can't leave the house until after 8 a.m. and must be back home by 9 that night. He must also consent to alcohol and drug tests and has a GPS monitoring system on his ankle.
