The mother of a Texas teenager who used an "affluenza" defense after killing four people in a drunken wreck has posted a reduced bond and is expected to be released soon.

In a tweet late Monday night, Tarrant County Sheriff Dee Anderson said Tonya Couch had posted $75,000 bond and was expected to be released Tuesday morning after being fitted with a GPS monitor, "barring any unseen delays."

A judge decreased Couch's bond Monday from $1 million to $75,000. She was brought back to Texas last week after being caught with her son, 18-year-old Ethan Couch, in the Mexican resort town of Puerto Vallarta. She's now charged with hindering the apprehension of a felon.
