The Texas teenager who used an "affluenza" defense in a deadly drunken-driving wreck grew up in a wealthy yet unstable household.

Court records show Ethan Couch's parents underwent an acrimonious divorce that included accusations that his mother was addicted to pain pills and his father was physically and verbally abusive.

The divorce provides a revealing backdrop for the latest chapter in Couch's troubled life: The teen and his mother were arrested Monday after fleeing to Mexico while he was on probation.

In 2006, a social worker concluded that the Couches had allowed their then-9-year-old son to become overly involved in adult issues and decisions.

On Wednesday, he won a three-day delay in deportation that could allow him to challenge efforts to send him back to the U.S.
