Past Cases May Indicate Likelihood of US Student's Release by North Korea

Student Otto Warmbier, 21, is not the first to be held in the country.

— -- While efforts to free Otto Warmbier, a U.S. student who was sentenced to 15 years hard labor in North Korea after attempting to steal a propaganda poster, are underway, history suggests that the odds of his being released are in his favor.

The Associated Press has identified at least seven Americans who have been held and then released from North Korean detention. An eighth, Sandra Suh, is still being held after being detained in April 2015, as she stands accused of making anti-North Korean propaganda during her visit, according to the AP.

The involvement of U.S. government officials seems to be a common theme in the release of Americans.

"He did a college prank, a mistake, but 15 years to be sentenced. That's crazy," Richardson said. "Hopefully now after this sentencing, it'll mean negotiations can start on his release on humanitarian grounds."

Warmbier was found guilty of subversion after taking a propaganda poster from a restricted area in the hotel where he had been staying during a group trip to the country.

The State Department warns on its travel warning page that "U.S. citizens to North Korea is not routine, and U.S. citizens have been subject to arrest and long-term detention for actions that would not be cause for arrest in the United States or other countries."

White House spokesman Josh Earnest said Wednesday it is becoming increasingly clear that the North Koreans see the arrest and detention of an American as a bargaining opportunity.

"Despite official claims that U.S. citizens arrested in North Korea are not used for political purposes,” he said, “it is increasingly clear that the North Korean government seeks to use these U.S. citizens as pawns to pursue a political agenda.”
