Ethan Couch, ‘affluenza teen,’ caught in Mexico with mom

They will probably be extradited back to the US before being set free because they have lived a life of privilege and just didn’t know any better.

Mexican authorities have detained Ethan Couch and his mother, Tonya Couch, in the beach resort town of Puerto Vallarta, the Tarrant County district attorney’s office confirmed late Monday.

Couch, 18, had been on the run since missing an appointment with his probation officer earlier this month — a violation of a 10-year-probation sentence he received for drunkenly killing four with his Ford F-350 pickup in 2013.

Couch and his mother were captured at about 6 p.m. Monday at an intersection in Puerto Vallarta after they couldn’t prove they were legally allowed to be in the country, ABC News reported early Tuesday.
