Ethan Couch, Texas' so-called "affluenza" teen, may have been forced to go to Mexico when his probation officer was not able to reach him December last year, according to his lawyer. 

In a Fort Worth courtroom on Tuesday, Couch's attorney Scott Brown argued that his client's case cannot be transferred to adult court due to lack of evidence that the 18-year-old manslaughter convict "voluntarily absented himself" during the scheduled hearing.

While it may have been easy to assume that Brown's argument meant Couch was taken against his will, the "affluenza" teen's lawyer claimed that it was not what he said.

"I don't think that's what I said. As far as Ethan being taken against his will, we are examining the facts, investigating the facts," he told CNN, as published online on Wednesday.

Couch's U.S.-based lawyer also explained that the entire situation is still unclear, and that he is merely presenting a possibility.

"This is an evolving process, and whether he was voluntarily or involuntarily taken to Mexico is something that's being investigated," he told CNN.

According to CBS News, the situation stemmed from allegations that Couch fled to Mexico with his mother, which violated his probation.

"The two were caught last month in Mexico, and Couch's mother was quickly deported. But the 18-year-old won a delay, based on a constitutional appeal that normally leads to a lengthy trial process," the report read.

CBS News also revealed that Couch's Texas-based lawyers have already filed the necessary documents to drop any objections against their client's deportation back to the United States, though authorities claimed that there remain no sign that the defendant has agreed to his deportation.

At the moment, the "affluenza" teen remains detained at a Mexico City detention facility.

Couch's case began in 2013 when he was caught in a drunk-driving incident, where four people were killed and nine others incurred bodily injuries.

According to a past CNN report, Couch's pickup truck 'plowed' into the pedestrians on the roadside of Burleson as well as a parked car.

He was only 16 years old at the time, so his case was filed in juvenile court. Despite this, prosecutors asked for a maximum sentence of 20 years imprisonment for the suspect.

However, his lawyers called forth a psychologist on the witness stand, declaring the teen a "victim" himself for having "affluenza," and that he needed treatment.

In the end, Couch was sentenced with 10 years of probation, and was given the moniker "affluenza teen."
