In 2013 Ethan Couch pleaded guilty to killing four people after he crashed his truck while driving drunk.

He was sentenced to probation and treatment after an expert testified that Couch suffered from "affluenza" and was raised without consequences or rules due to his parent's wealth.

This month an anonymous Twitter user posted a video of someone she claimed to be Couch at a party. It could represent a violation of his probation.

Shortly after, Couch disappeared.

US Marshalls and the FBI are now assisting in the search for Couch and his mother.
