'"Affluenza Teen" Ethan Couch has been transferred from a juvenile detention center to an adult, maximum security jail cell in Texas.

CNN reports the now 18-year-old Couch remains jailed in connection with a 2013 drunken-driving crash that killed four people and injured several others. More recently, Couch had been sought after skipping out on his probation and fleeing to Mexico with his mother after video of him attending a party where alcohol was served publicly surfaced, a direct violation of his probation.

Judge Tim Menikos has yet to rule if Couch will be charged in juvenile or adult court stemming from the probation violation. Tarrant County Sheriff Dee Anderson said a hearing on the matter has been scheduled for February 19.

"The only change that was made in this order was his housing change," added Anderson. "We will house him as we do any adult prisoner except that he's under the jurisdiction of the juvenile court."

Couch could ultimately be sentenced up to four months in jail and his attorney Scott Brown has indicated they do not plan to fight a transfer of the case to adult court.

Just two years into his 10 year sentence, Couch was tracked to Mexico after several weeks on the run. He was returned here to the U.S. late last month under federal custody.

Couch became a household name back in 2013 when attorneys for him successfully used the "affluenza" defense in arguing that he should not be sentenced to jail following the deadly crash because his troubles were at least partly caused by indulgent parents who regularly failed to set rules for him.

Couch's mother, Tonya, was with him at the time of his Mexican capture and is facing a separate investigation. She already faces formal charges of hindering her son's apprehension.

Meanwhile, Mothers Against Drunk Driving members have launched a petition aimed at making certain Couch is now charged as an adult.

Fox News reports MADD National President Colleen Sheehey-Church recently reflected, "Couch has been found, and everything possible must be done to hold him accountable and to ensure that Couch has no more victims. Couch is not a child. His actions are not that of a child. Four people were killed and several injured, and Couch continues to show no remorse and blatant disregard for the law."

MADD officials point out to now have the case transferred to adult court would allow a judge the option of extending his probation beyond his 19th birthday, thus putting him under the direct threat of a much harsher sentence if he were to ever again be found in violation.
