Ethan Couch—a.k.a. Ya Boy, a.k.a. the Affluenza Teen—was deported from Mexico on Thursday and booked into a Fort Worth, Texas, juvenile detention center, the Associated Press reports. “We’ve reached a great milestone,” Tarrant County Sheriff Dee Anderson said outside the facility.

It’s been more than a month since Couch and his mother left the country, possibly violating the terms of his probation. Tonya Couch was deported in December.

“This is a day we’ve looked forward to, when we have them both here and back under the jurisdiction here. We’re hoping that the day comes for justice for the families and the four victims that were killed,” Sheriff Anderson said. From the AP:

Couch is scheduled for a court hearing Friday where a judge could decide to move him to an adult jail, which Anderson said he would support given the severity of Couch’s offenses. Couch also faces a hearing on Feb. 19 to determine whether his case will be transferred to the adult system, where he could face more time behind bars.

“He’s certainly capable of understanding now what’s going on, and I’d feel better if he was there (in an adult jail),” Anderson said.

Authorities believe Couch and his mother fled Texas in her pickup truck in early December, after an online video appeared to show Couch at a party where people were drinking. Couch was sentenced to 10 years’ probation in juvenile court for the 2013 wreck that killed four people and injured several others. The terms prohibit him from drinking or leaving Tarrant County, Texas.

Tonya Couch, who was reportedly armed, and paid her son’s strip club bills, was released on bond earlier this month, fitted with an ankle monitor and charged with hindering the apprehension of a felon.

“I believe he is relieved to be coming back. I think he has come to terms with this,” his Mexican attorney, Fernando Benitez, told NBC News on Wednesday. “He decided that he would much rather face American justice than drag it out here in Mexico.”
