A warrant has been issued to apprehend Ethan Couch, police confirm to PEOPLE, after the Texas teenager – who killed four people in a drunk-driving crash in the so-called “affluenza” case in 2013 – allegedly missed a check-in with his probation officer.

Fort Worth police told PEOPLE Wednesday that the warrant was issued in Tarrant County on Dec. 11. Couch’s lawyers told the Dallas Morning News in a statement that a juvenile probation officer has been unable to reach Couch, 18, or his mother for several days.

“It’s our understanding that the court has issued a directive to apprehend to have Ethan detained because he is out of contact with his probation officer,” the lawyers’ statement said.

Couch’s father said he didn’t know where the mother and son were, either, WFAA-TV reports.

The warrant comes just weeks after Couch allegedly appeared in a six-second video posted to Twitter showing young men playing beer pong, NBCDFW.com reports.

The Tarrant County district attorney’s office has been looking into that video, as the terms of Couch’s probation prohibit him from using drugs or alcohol.

Couch is serving 10 years probation, having avoided jail time in the controversial case after his lawyers argued that he suffered from “affluenza” – that he was irresponsible because he’d been overly coddled by his wealthy parents.

Recently released deposition tapes from the case suggested Couch often lived alone in a 4,000-square-foot house with a pool and wet bar and did drugs including Valium, Hydrocodone, marijuana, cocaine, Xanex and ecstasy.

Couch testified that on the night of the June 15, 2013 crash, he didn’t even remember pulling out of the driveway, much less plowing into a group of people helping a stranded motorist, killing four of them.
