The Latest on the case of Ethan Couch, the 18-year-old who used an "affluenza" defense in a fatal 2013 drunken driving wreck in Texas and was recently deported from Mexico (all times local):

10:50 a.m.

"Affluenza" teenager Ethan Couch is in a Texas courtroom to face his first hearing since being deported from Mexico.

The 18-year-old was sentenced to probation for a 2013 drunken-driving wreck that killed four people near Fort Worth. Authorities believe he and his mother fled to Mexico in early December, as prosecutors in Texas investigated whether he may have violated his probation.

A judge is expected to decide during Friday's hearing whether to keep Couch at the juvenile facility where he was taken after arriving back in Texas on Thursday.

The judge also could decide to move Couch to an adult jail to await a February hearing that will determine whether the case is transferred to the adult system, where Couch could face time behind bars.

During the sentencing phase of Couch's 2013 trial, a defense witness argued Couch had been coddled into a sense of irresponsibility by his wealthy parents and deemed the condition "affluenza."

The Texas teenager who used an "affluenza" defense in a fatal drunken-driving wreck is expected to learn whether he'll be moved to an adult jail as he awaits a judge's ruling on transferring his case to the adult system.

A hearing is scheduled Friday for 18-year-old Ethan Couch. He was deported from Mexico on Thursday and taken to a juvenile detention facility in Fort Worth.

Authorities believe Couch and his mother fled to Mexico as Texas prosecutors investigated whether he may have violated his probation in the drunken-driving case. Couch was 16 at the time of the wreck, so the case is being handled for now in juvenile court.

A judge will decide Friday whether to move Couch to an adult jail, keep him at the juvenile facility or to let him go before a February hearing.
