Texas teen Ethan Couch appears to have dyed his hair black when he fled the US for Mexico with his mother earlier this month, violating his probation.
Couch - now 18 years old - was serving a 10-year probation sentence for killing four people while driving drunk when he was 16.
He "became known as the 'affluenza' teen during his trial in juvenile court, when a psychologist said he was so wealthy and spoiled he could not tell the difference between right and wrong," according to Reuters.
According to a photo released by the Jalisco State Prosecutor's Office, Couch - who has appeared with blonde hair in all previously released images - has drastically changed the color of his hair and beard:
Mexican authorities arrested Couch and his mother Tonya Couch on Monday:
