A judge has issued a warrant to have Couch detained, his lawyers say

Ethan Couch's probation officer has not been able to reach him or Couch's mother

Couch was convicted two years ago at age 16 of killing four people while driving drunk

CNN  — 

A warrant has been issued to take a teenager into custody who, two years ago, made national news when he was sentenced to probation in Texas for a drunken driving crash that killed four people. Ethan Couch’s defense coined an infamous defense – that he suffered from “affluenza,” or that he was a rich kid who was less to blame for his crime because his parents didn’t set limits for him.

Couch’s probation officer couldn’t reach him this week, his lawyers told CNN. Couch’s mother, with whom the 18-year-old had been living, is also missing, said attorneys Scott Brown and William Reagan.

Under the terms of his probation, Couch isn’t supposed to lose contact with his probation officer, his lawyers said.

Their apparent disappearance comes shortly after the video of Couch at a party turned up on social media, CNN affiliate KTVT reported.

When asked to confirm Couch’s attendance at the event, his attorneys told CNN’s sister network HLN they “are aware that the probation authorities and/or the District Attorney’s office are conducting an investigation to determine if Ethan has violated any of the terms and conditions of his probation. It would not be prudent for us to make any further statement on Ethan’s behalf until the investigations are concluded and it is determined what, if any, action will be taken against him.”

Jail time possible if probation terms violated

Couch’s attorneys argued in 2013 that his parents, because they spoiled him, were partly to blame for the crash on a road in Burleson, south of Fort Worth.

Lawyer blasts media for ‘affluenza’ focus

Prosecutors had asked for 20 years behind bars, but a Tarrant County juvenile court judge sentenced Couch to a decade of probation. Couch was ordered into long-term mental health treatment, away from his parents’ influence.

After his recent disappearance, a court ordered Couch detained, according to his lawyers. At the time of his conviction, prosecutors said Couch could face up to 10 years of incarceration if he violated the terms of his probation.

A psychologist testified in court that Couch, who was 16 at the time, suffered from “affluenza.”

The approach was met with widespread outrage and disdain, and the term “affluenza” was widely mocked.

Drunken crash

On the night of June 15, 2013, Couch and some friends stole beer from a Walmart.

That same evening Hollie Boyles and her daughter Shelby left their home to help Breanna Mitchell, whose SUV had broken down by the side of a road. Brian Jennings, a youth pastor, was driving past and also stopped to help.

Couch plowed into them, killing them all. The crash threw two passengers out of the bed of Couch’s truck, injuring both severely.

The parents of one of the injured teens, who suffered debilitating brain injuries, sued Couch’s family for $2 million.

Three hours after the crash, tests showed that Couch had a blood-alcohol content of 0.24, three times the legal limit. Couch’s vehicle also struck a parked car, which then slid into another vehicle headed in the opposite direction.

Eric Boyles, Hollie’s husband and Shelby’s father, felt the judge had been far too easy on Couch and angrily spoke out against how Couch was treated. The message the judge sent is all wrong, he said.

“The primary message has to absolutely be that money and privilege can’t buy justice in this country,” he said.
