Drunk Driving Killer Ethan Couch Transferred to Adult Men’s Prison

NBCNews.com:

The Texas teenager whose lawyers infamously invoked an "affluenza" defense while he was on trial for a fatal drunken-driving crash was moved from a juvenile detention facility to an adult jail Friday. 

Ethan Couch, 18, was booked at 1:45 p.m. The move does not mean that Couch's probation case will be transferred to the adult system, officials said. 

"He was very soft spoken, not at all defiant," Tarrant County Sheriff Dee Anderson said, recalling their three- to four-minute conversation. "He made no requests, voiced no concerns about what was happening." 

Anderson said he did not know why the judge decided Thursday to transfer Couch before a scheduled Feb. 19 hearing where he will decide if Couch's controversial case belongs in the adult system.
