Mystery swirls around US soldier who entered North Korea days ago, officials say

New details emerged Friday that might provide clues in the mystery about why a 23-year-old U.S. Army private crossed the border into North Korea earlier this week.

A U.S. official confirms that on Sept. 4, 2022, Pvt. Travis King failed to report for his daily formation, and when reached away from the base stated that he “refused to return to post or America.”

At the time, King was serving as a cavalry scout at Camp Bonifas, which is located just south of the southern end of the DMZ in northwest South Korea.

As a scout, and because of where he was serving, King would have been aware of the risks in crossing the DMZ, officials said.

King was later found in Uijeongbu, a city located about 25 miles southeast of Camp Bonifas.

Also on Friday, Secretary of State Antony Blinken, speaking at the Aspen Security Forum in Aspen, Colorado, made his first public comments about King.

“We are very concerned of course about his well-being,” Blinken said. “We’d like to know his whereabouts. We have communicated to North Korea seeking that information. I don’t have anything more at this point.”

Asked whether King might be tortured, Blinken said, “there are certainly concerns based on what we have seen in the past and the way North Korea has treated those it detained.”

American officials try to gain clarity on his location or condition — and even the circumstances that led him to cross the border.

The Pentagon announced on Thursday that Army counterintelligence officials were investigating what prompted King to separate from a tour group visiting the Demilitarized Zone dividing South and North Korea, where witnesses say he sprinted across the border sometime on Tuesday.

He was originally supposed to fly out of Seoul after being taken to the airport on Monday, officials have said. Back in Texas, he was set to face a “pending administrative separation actions for foreign conviction,” one U.S. official has said. He had been in detention for more than a month after an altercation with locals, according to an official.

So far, efforts to gather information have been hamstrung by Pyongyang’s stonewalling. Although various agencies and intermediaries have attempted to communicate with the North Korean government about King, none say they have received any response and the country’s state media has also remained uncharacteristically silent.

“We’re still doing everything we can to try to find out his whereabouts, his well-being and condition and making it clear that we want to see him safely and quickly returned to the United States and to his family,” White House spokesman John Kirby said Thursday.

“Not for lack of trying, we just don’t have anything,” he said.

One U.S. official said that after King entered North Korea, he was immediately taken away in a van. But the Pentagon says they see no reason to suspect the soldier planned his crossing with the North Korean government.

Asked whether the State Department feared for King’s safety, its spokesperson Matthew Miller said Thursday that Pyongyang’s past treatment of American nationals held in its custody was cause for worry.

“Certainly, I think we would always have concern given the treatment by North Koreans of past detained individuals — we would have that concern and that’s why, one of the reasons why, we are reaching out to ask for more information about his well-being,” he said.

But those asks continue to go unanswered — illustrating just how much communication between the countries has deteriorated under the Biden administration.

Although the U.S. government has made multiple attempts to engage with Pyongyang on issues like nuclear proliferation, those efforts have yet to elicit any response from the hermit kingdom.

“There is no regular contact. I will say communications between our two countries are limited,” Miller said.

Anthony Ruggiero, senior director of the Foundation for Defense of Democracies’ Nonproliferation and Biodefense Program and the former deputy assistant to the president for national security affairs, said North Korea may just be biding its time.

“They’re probably taking the time to speak with [King] and see what to do next,” Ruggiero said.

In prior cases involving Americans held in North Korea, Pyongyang has ignored outreach from the U.S. and Sweden — America’s diplomatic liaison in North Korea — for weeks on end.

Ruggiero said that Pyongyang could seek to turn the latest incident into “a benefit” if it senses having the American soldier in its custody is a source of diplomatic pull.

If that’s the case, Ruggiero explained, its reticence to engage with U.S. officials could evaporate.

“I think you’re likely to see that the North Koreans want to talk to an American official directly as possible,” he predicted.

Kim Jong Il, the former supreme leader of North Korea and father of its current ruler, Kim Jong Un, approved the release of American detainees after visits from former Presidents Jimmy Carter and Bill Clinton.

But even if there is direct contact between the U.S and North Korea, Ruggiero and other experts expect that the Biden administration will be reluctant to expend any significant political capital to secure the freedom of a soldier who fled while facing disciplinary action.

If that’s the case, North Korea may elect to release King, Ruggiero said, as they did with Bruce Byron Lowrance — a U.S. national who entered North Korea in 2018 and was freed a month later — a move that helped set the stage for the first summit between then-President Donald Trump and Kim Jong Un.

“The North Koreans may believe that this is more headache than it’s worth,” Ruggiero said.
