Her husband was set to end a 10 day tour of North Korea on Oct. 26. But just before he was slated to fly out, he was escorted from his flight by a North Korean official.
"We have had no word on the state of his health, whether or not the medications sent to him through the Swedish Embassy in North Korea have been delivered or why he was detained," she said.
Newman doesn't fit the pattern of other Americans detained by North Korea in recent years.
By all accounts, he wasn't a missionary or a journalist. He had no apparent political or religious agenda for the government of Kim Jong Un. Instead, he visited North Korea as a curious tourist, according to his son, eager to reconnect with a country where he'd served as an infantryman during the Korean War, six decades ago.
The mystery, then, about why Pyongyang has held him for a month has baffled Newman's friends and family — as well as analysts who study North Korea.
"We're concerned about him," said Barbara Ingram, a neighbor n the Channing House retirement community, an 11-story apartment house where the Newmans live.
"I find this pretty weird," Robert Kelly, a political scientist at Pusan National University in South Korea who has traveled as a tourist to North Korea, said of Newman's detention. "I don't see any of the usual signs — such as missionary activity or overt law-breaking — that lead to detention."
Whatever the reasons behind the detention, it could hurt impoverished Pyongyang's efforts to encourage a growing tourism trade seen as a rare source of much-needed foreign currency. "This obviously jeopardizes North Korea's long, painstaking effort to build a tourism industry," Kelly said in an email.
Tourism is picking up in North Korea, despite strong warnings from the U.S. State Department, most recently this week, about the risk of arbitrary detention. Americans travel there each year, many as part of humanitarian efforts or to find long-lost relatives or to see a closed society few outsiders get to visit.
Newman has been described as an inveterate traveler and long-retired finance executive. His son, Jeffrey Newman, said his father wanted to return to the country where he spent three years during the Korean War.
North Korea has detained at least six Americans since 2009, including two journalists accused of trespassing and several Americans, some of whom are of Korean ancestry, accused of spreading Christianity.
Kenneth Bae, a Korean-American missionary and tour operator, has been detained for more than a year. North Korea sees missionary work as a Western threat to its authoritarian government.
It's possible that North Korea could try to use Newman as a diplomatic pawn in an interminable nuclear standoff with Washington — something analysts say Pyongyang has done previously with detained Americans. Several of them were only released after high-profile visits to Pyongyang by prominent Americans, including former Presidents Jimmy Carter and Bill Clinton.
