Couch, 22, who killed four people in a drunk driving crash in June 2013 when he was a teenager, was originally sentenced to 10 years probation for intoxication manslaughter.

When he violated his probation, he was forced to serve two years in jail.

Last April, a judge has revoked bond for Tonya Couch, 53, after she failed a urine test required as a condition of her bond but don’t specify the substance the urinalysis revealed.
