The father of “affluenza” teen Ethan Couch was charged with assault for allegedly choking his girlfriend, according to Texas prosecutors.

The District Attorney in Tarrant County said that Frederick Couch was charged in the alleged choking incident in July, according to an NBC affiliate in Dallas-Forth Worth.

Couch, 53, is the father of Ethan Couch, who was driving drunk and under the influence of marijuana and prescription drugs when he barreled into a group of good Samaritans who had stopped to help a disabled driver in June 2013. Four people were killed and nine injured in the accident on a rural road southwest of Dallas.

Attorneys at his trial invoked the “affluenza” defense.

A psychologist who testified on the teen’s behalf said that Ethan, who was 16 when the accident took place, suffered from being so spoiled by both his parents that he was unable to distinguish right from wrong. A juvenile court sentenced him to 10 years of probation, and forced him to enter an alcohol and drug rehabilitation program.

The judge’s sentence, which allowed him to avoid time in jail, was roundly condemned by the victims’ families and anti-drunk driving groups.

Two years later, when Ethan was found to have violated the terms of his probation by drinking alcohol at a party, he fled with his mother to a resort in Mexico. The mother and son were extradited to the US in 2016 where Ethan was sent to jail for 720 days.

Ethan’s father is due in court next month to face the assault charges.
