Earlier this month, officials in Tarrant County, Texas, said they were investigating whether Couch, who is now 18, had violated his probation. Couch went missing soon afterward, along with his mother, Tonya Couch, who is 48 years old. U.S. and Mexican authorities said they fled to Mexico and were arrested Monday near the resort town. A photograph of Couch released by the Jalisco attorney general after Couch’s arrest showed his blonde hair had been dyed dark brown. It’s unclear when Couch colored his hair.
“We’re working to get him back up here,” David Oney, a spokesman for the United States Marshals Service, told The New York Times. “But we don’t know when.”
The Jalisco State Prosecutor’s Office in Mexico told ABC News in a statement that Couch and his mother were arrested in a Puerto Vallarta neighborhood on Monday at about 6 p.m. They will be repatriated to the U.S., the statement said.
Couch came into national prominence after the judge in his case in 2013 showed him leniency after several people testified that the then 16-year-old suffered psychological problems because of his family’s wealth—a condition dubbed “affluenza.” Couch pleaded guilty to four counts of vehicular manslaughter and was sentenced to 10 years probation. Prosecutors in the case had sought a prison sentence.
