Washington: What led to US student Otto Warmbier's death? The 22-year-old was detained in North Korea for 17 months and died just days after he was released and repatriated to the US.
Physicians at the University of Cincinnati Medical Center, where he died, said last Thursday that Warmbier showed no sign of understanding language or awareness of his surroundings, and had made no "purposeful movements or behaviours,' though he was breathing on his own.
Warmbier's father, Fred Warmbier, said last week that his son had been "brutalised and terrorised by the Pyongyang government and that the family disbelieved North Korea's story that his son had fallen into a coma after contracting botulism and being given a sleeping pill. Doctors who examined Otto Warmbier after his release said there was no sign of botulism in his system.
