A 20-year-old Texas man who as a teenager invoked "affluenza" in his defense after killing four people in a drunken wreck has been released from jail. Tarrant County sheriff's spokesman David McClelland says Ethan Couch was released Monday from the county jail near Dallas after serving nearly two years for a revoked probation.

His attorneys used the now-famous "affluenza" defense, claiming Couch didn't know the difference between right and wrong because of his wealthy upbringing.

Tall, lean, and lantern-jawed, Jamison Monroe Jr. could pass for a third Winklevoss brother.

He was a spoiled rich kid, the namesake of a prominent Houston financier

Maria Lemus’ teenage son used to love soccer. He used to have friends. He used to be a normal kid.

He can communicate only by blinking. “People say we have to die to go to hell,” his mother said. “To me, I’ve already been there.”

Ethan Couch's case will be transferred to an adult court, judge Tim Menikos ruled in a Tarrant County juvenile court hearing Friday morning. Couch's case will be transferred by his 19th birthday in April. He will remain in jail until then. He has been in a single cell in adult jail since he returned from Mexico, where he fled with his mother after video surfaced, allegedly showing him violating his probation.

One 16-year-old drove drunk, ran a red light and crashed into a pregnant woman's car, killing her and her unborn child. Another drunken teenager rammed a pickup truck into a crowd of people assisting a stranded driver, killing four. Jaime Arellano went to prison. Ethan Couch went free. The stories of the two Texas teens illustrate how prosecutors' decisions in similar cases can lead to wildly different outcomes. The poor immigrant from Mexico...
