FORT WORTH (CBSDFW.COM) – A judge has revoked bond for the 50-year-old mother of a teenager who used an “affluenza” defense regarding a fatal drunken-driving wreck.

Tonya Couch was arrested earlier today on a probation violation.

She was booked into the Tarrant County jail Wednesday. Court documents show that she failed a urine test required as a condition of her bond but don’t specify the substance the urinalysis revealed.

The 20-year-old who as a teenager used an “affluenza” defense regarding a drunken-driving wreck that killed four people was sentenced to probation. But he violated that probation when he ran to Mexico and has served nearly two years in jail.

He’s set for release on April 2.
