He’s still serving his sentence. After more than 17 months in a North Korean prison, 22-year-old Otto Warmbier headed home on Tuesday, but his parents say he’s been comatose for 15 months after being “brutalized” by his captors. A University of Virginia student on a tour, he was arrested in January 2016 and sentenced to 15 years imprisonment for allegedly stealing a political banner. Pyongyang said that Warmbier contracted botulism after his trial, was given a sleeping pill and never awakened. His chance of recovery is uncertain.
