FORT WORTH - A judge has sharply reduced the bond of the mother of a Texas teenager who used an "affluenza" defense after killing four people in a drunken wreck.

Tonya Couch's new bond was set Monday at $75,000, down from $1 million.

Tonya Couch was brought back to Texas last week after being caught with 18-year-old Ethan Couch in the Mexican resort town of Puerto Vallarta. She's now charged with hindering the apprehension of a felon.

State District Judge Wayne Salvant said Monday that her original bond was too high for the charge she faces. Salvant ordered Couch to wear a GPS monitor if she posts bond.

Ethan Couch, who remains in a Mexico City detention facility, drunkenly crashed into a crowd of people in June 2013, killing four people. He received 10 years' probation.
