Couch admitted to causing the wreck and received 10 years’ probation from State District Judge Jean Boyd rather than prison time, as prosecutors and Couch’s victims wanted. Several of his victims have since sued the Couch family, with most of them reaching confidential settlements.

Debbie Spoonts, placement supervisor for Tarrant County Juvenile Services, said the facility decided what Fred and Tonya Couch would pay based on a sliding scale.

A message from The Associated Press seeking comment from Spoonts on the facility’s payment policy was not immediately returned Friday.

The teen’s family previously had offered to pay for Couch to go to a $450,000-a-year rehabilitation center near Newport Beach, Calif. Boyd rejected that request.
