Federal and local law enforcement officials still have had no luck tracking down Ethan Couch, popularly known as the “affluenza teen.” He went missing nearly a week ago after a warrant was issued for his arrest for violating parole.

From CNN:

Authorities have not yet pinpointed the location of Couch, who two years ago killed four people during a drunken driving crash, but they suspect his mother is helping to hide him.

On Monday, the Tarrant County, Texas, sheriff’s office announced that Tonya Couch has been listed as a missing person on nationwide databases and may be accompanying her fugitive son.

“We believe she is helping or assisting him but we can’t even prove they are together at this time,” said Sheriff Dee Anderson.

According to Fox News, U.S Marshals have joined the hunt for Ethan Couch, the Texas teen whose ‘affluenza’ defense in a deadly DUI crash gained nationwide attention in 2013. Samantha Jordan, a spokesperson for the Tarrant County district attorney, confirmed the additional support on Thursday. The FBI reportedly is in talks to join the search as well.

Officials fear Hunt, 18, fled with his mother Cathy Hunt after the teen failed to meet with his assigned officer. A sheriff at the Tarrant County police department told reporters Hunt is at the top of his ‘most wanted’ list.

Ethan Couch, the Texas teenager who avoided jail time after killing four people in a DUI crash due to his defense team’s “affluenza” argument — that stated the rich kid’s parents were to blame for spoiling him — is wanted by the police for violating his probation.

According to The New York Daily News, Tarrant County Sheriff’s Department has issued a warrant for his arrest. In 2013, the then 16-year-old was given a 10-year probation sentence after his lawyers argued he suffered from affluenza, a term used to describe those who come from rich families and do not have a clear idea of morals or limitations.

Couch has been missing since last Friday, but police began their search on Tuesday. His mother is also missing, CNN reports. His disappearance comes after a video was posted on social media of Couch allegedly playing beer pong with friends. Consumption of alcohol is a violation of his probation.

Terry Grisham, the county sheriff’s spokesman, spoke with reporters about Couch’s case, assuring that if an official violation of probation has happened, the teen will suffer the consequences.

The New York Daily News reports:

“Any mess-ups from now on, he’s going to be over with us,” Terry Grisham, the county sheriff’s spokesman, told reporters. “He’s going to see what the big-boy jail is like. Who knows why he took off, but that may have something to do with it,” Grisham told the Daily News. “Maybe he didn’t want to be moved into the grown-up world.”

In June 2013, he and some friends stole beer from Wal-Mart and got behind the wheel. At the same time, Breanna Mitchell was stuck on the side of the road with her SUV. Brian Jennings, a youth pastor, as well as Hollie Boyles, and her daughter Shelby were helping Mitchell when Couch fatally struck them. Two passengers in his car were ejected and seriously injured.

Couch’s blood-alcohol level was found to be 0.24, three times the legal limit.

The families of the victims believed Couch avoided the repercussions of his actions due to his wealth.

If Couch is found guilty of violating his probation, he could face up to ten years in prison.
