CINCINNATI — Otto Warmbier, an American college student who was released by North Korea in a coma last week after almost a year and a half in captivity, died Monday, his family said.
The 22-year-old ‘‘has completed his journey home,’’ the family said in a statement.
‘‘Unfortunately, the awful, torturous mistreatment our son received at the hands of the North Koreans ensured that no other outcome was possible beyond the sad one we experienced today,’’ his parents said.
Doctors had described his condition as a state of ‘‘unresponsive wakefulness’’ and said he suffered a ‘‘severe neurological injury’’ of unknown cause.
His father, Fred Warmbier, said last week that he believed Otto had been fighting for months to stay alive to return to his family. Their statement Monday said he looked uncomfortable and anguished after returning June 13, but his countenance later changed.
‘‘He was at peace. He was home, and we believe he could sense that,’’ they said.
Warmbier was convicted of subversion after he tearfully confessed that he had tried to steal a propaganda banner while visiting with a tour group from China. He was sentenced to 15 years in prison with hard labor in North Korea.
The University of Virginia student was held for more than 17 months. His family said they were told he had been in a coma since soon after his March 2016 sentencing.
Doctors said he suffered extensive loss of brain tissue and ‘‘profound weakness and contraction’’ of his muscles, arms, and legs. His eyes opened and blinked but without any sign that he understood verbal commands or his surroundings.
North Korea said he went into a coma after contracting botulism and taking a sleeping pill. Doctors in Cincinnati said they found no active sign of botulism or evidence of beatings.
His parents said the day of his release that they wanted ‘‘the world to know how we and our son have been brutalized and terrorized by the pariah regime’’ and expressed relief he had been returned to ‘‘finally be with people who love him.’’
Fred Warmbier praised his son’s ‘‘performance’’ and President Trump’s administration. He was critical of the approach to his son’s situation taken by former president Barack Obama’s administration.
In a White House statement, Trump said, ‘‘Lot of bad things happened, but at least we got him home to be with his parents.’’ He called North Korea a ‘‘brutal regime.’’
The younger Warmbier grew up in the northern Cincinnati suburb of Wyoming. He was salutatorian of his 2013 class at a highly rated high school, and was on the soccer team, among other activities.
Ohio’s US senators sharply criticized North Korea last week.
Senator Rob Portman, a Republican, said North Korea should be ‘‘universally condemned for its abhorrent behavior.’’ Senator Sherrod Brown, a Democrat, called the country’s actions ‘‘despicable.’’
The Warmbiers have ‘‘had to endure more than any family should have to bear,’’ Portman added.
Three Americans remain held in North Korea. The US government accuses North Korea of using such detainees as political pawns. North Korea accuses Washington and South Korea of sending spies to overthrow its government.
At the time of Warmbier’s release, a White House official said Joseph Yun, the US envoy on North Korea, had met with North Korean foreign ministry representatives in Norway the previous month.
Such direct consultations between the two governments are rare because they do not have formal diplomatic relations.
At the meeting, North Korea agreed that Swedish diplomats could visit all four American detainees.
Yun learned about Warmbier’s condition in a meeting a week before the release from the North Korean ambassador at the UN in New York. Yun then was dispatched to North Korea and visited Warmbier June 12 with two doctors and demanded his release on humanitarian grounds.
