Tonya Couch, who was apprehended in Mexico with son Ethan Couch after fleeing Texas in 2015, has been arrested again.

Couch, 50, was booked into the Tarrant County jail Wednesday after authorities say she violated the conditions of her bond. Court documents indicate that she failed a urinalysis test.

Couch faces charges of hindering the apprehension of a fugitive and money laundering. She has been free on bond since 2016; as part of the conditions of her release, she is not allowed to drink alcohol.

Ethan Couch, now 20, was driving drunk when he crashed a pickup in June 2013, killing four people and seriously injuring two others.

He gained nationwide notoriety after a psychologist testified that he suffered from "affluenza" — arguing that the teen's relationship with his wealthy parents was dysfunctional and prevented him from having a sense of personal responsibility.

Couch pleaded guilty to intoxication manslaughter and was sentenced to 10 years of probation and rehab.

Two years later, video posted on Twitter appeared to show him playing beer pong — a probation violation. He then missed a meeting with his probation officer, and he and his mother fled to Mexico.

Authorities eventually tracked the pair to the resort town of Puerto Vallarta after they used a cellphone to order pizza from Dominos.

Ethan Couch's case was eventually moved to the adult court system and he was sentenced to 720 days in jail — 180 days for each person he killed. He is scheduled to be released April 2, just before his 21st birthday.

Prosecutors also claimed last year that Tonya Couch violated her bond conditions, alleging that she drank a beer at a sports bar and held a rifle at a gun show.

Judge Wayne Salvant ruled that Couch could remain free on bond, saying that he wouldn't put her in jail for sipping a beer but that she needed to use common sense.

"The eyes of Texas are looking upon you," Salvant said.
