THE Texas teenager dubbed the “affluenza teen” after he killed four people while driving drunk was released from jail overnight.

According to the New York Post, Ethan Couch — who infamously used his wealthy upbringing as a defence for his crime, saying it impaired his ability to tell right from wrong — served nearly two years at Tarrant County Jail for fleeing to Mexico after the fatal 2013 crash.

Couch is being released just days before his 21st birthday and will be under strict probation supervision, the county sheriff’s office said.

The then-16-year-old had a blood-alcohol level three times the legal limit for adult drivers when he hit and killed four people with his pick-up truck.

Couch earned his nickname when a psychologist testified on his behalf, saying he suffered from “affluenza”, which made him incapable of fully accepting responsibility.

He pleaded guilty to intoxication manslaughter — and was sentenced to 10 years’ probation, sparking widespread outrage.

But Couch still ended up behind bars after he was caught playing beer pong in a 2015 video in violation of his probation. A judge then ordered him to serve 720 days in jail — 180 days for each of his victims.

Couch’s mother, Tonya, 50 — who was free on bond while awaiting trial on charges she helped Ethan flee south of the border — was arrested last week for violating conditions of her bond, which included not drinking alcohol.

Court documents showed she failed a urine test, according to the Dallas Morning News.
