And Ethan Couch, the white Texas teenager spared jail time after he killed four people in a drunk-driving crash, has been detained with his mother by authorities in Mexico. Ethan Couch killed a motorist and three Good Samaritans who had stopped to help her, and left one of his friends with brain damage. But he was sentenced to no time in jail after a psychologist testified he had “affluenza”—meaning his wealthy upbringing left him unable to tell right from wrong. Couch disappeared with his mother after video appeared to show him at a party, a possible violation of his probation. He and his mother were detained near the Mexican beach resort of Puerto Vallarta.
