A grand jury on Thursday indicted Tonya Couch, the mom accused of helping the so-called "Affluenza teen" Ethan Couch escape to Mexico while on probation after a deadly drunken-driving crash.

The charges included hindering apprehension and related money laundering. 

In April, a judge in adult court ordered Ethan Couch to spend nearly two years in jail: consecutive 180-day sentencess for each of the four people he killed in 2013 when he rammed a pickup truck into a crowd of people helping a driver.

Couch was 16 and his blood-alcohol level was three times above the legal limit for adult drivers when the crash unfolded.

The teen ended up in trouble again late last year after a cellphone video showed him apparently playing beer pong at a party. Drinking alcohol is a violation of Couch's probation. Shortly after the video surfaced, Couch and his mother, Tonya, took off to Mexico.

The two were apprehended in a Mexican resort city in December and sent back to the United States. Prosecutors said Tonya Couch spent up to $150,000 to keep her son out of sight of law enforcement.

It was not his first run-in with the law. At 15, Couch was given two citations after a police officer found him behind the wheel of a pickup truck next to a half-naked girl, with an open vodka bottle on the backseat floor.

During the sentencing in the car crash trial, a psychologist suggested Ethan Couch had "affluenza," blaming the teen's parents for having "taught him a system that's 180 degrees from rational. If you hurt someone, say you're sorry. In that family, if you hurt someone, send some money."
