'Affluenza' Teen Ethan Couch Will 'Successfully Complete' Probation, Lawyers Say

Ethan Couch was transferred back to the U.S. this morning.

Ethan Couch arrived back in Texas this morning after being arrested in Mexico a month ago.

"We are optimistic that, going forward, Ethan will comply with all court-imposed terms and conditions and that he will successfully complete his term of probation," the statement read.

Ethan and his mother Tonya Couch sparked an international manhunt after he allegedly failed to appear at a court-mandated meeting with a probation officer.

Ethan Couch was put on probation in 2013 after killing four people while driving drunk.

During Ethan's sentencing in the drunken-driving trial, a psychologist hired by the defense testified that the teen was a product of "affluenza" -- a term he used to describe Ethan's irresponsible lifestyle associated with his affluent upbringing.

Ethan had a blood alcohol level three times the legal limit on the night of the crash.
