According to a report released in June by the government-run Korea Institute for National Unification in Seoul: "Prisoners sent to a total-control zone can never come out. They are put to work in mines or logging camps until they die. Thus the authorities don't even bother to give them ideological education. They only teach them skills necessary for mining and farming."

Thanks to the stories of former Yodok inmates, the camp's name has become synonymous with human rights abuses. But there are at least four other prison camps in North Korea, including Camp No. 14 in Kaechon. These others are far less known because so few have emerged to describe them.

Shin "is a living example of the most brutal form of human rights abuse," said Yoon Yeo Sang, president of Database Center for North Korean Human Rights in Seoul, where Shin is taking temporary shelter. "He comes from a place where people are deprived of their ability to have the most basic human feelings, such as love, hatred and even a sense of being sad or mistreated."

A North Korean named Kim Yong who came south in 1999 and now lives in the United States said he spent two years in Kaechon, but some refugees have questioned his claim.

Ahn Myeong Cheol, who worked as a driver and guard at four camps before reaching South Korea in 1994, has no doubts that Shin was in a total-control zone. Ahn said that when he met Shin in June, he immediately noticed the telltale signs: the avoidance of eye contact and arms warped by heavy labor from childhood.

"An instruction drilled into every guard's head is: Don't treat them like humans," Ahn said.

According to Shin, the prison authorities matched his father, Shin Kyong Sup, with his mother, Chang Hye Kyong, and made them spend five days together before separating them. This sort of arrangement was known as "award marriage," a privilege given only to outstanding inmates. An exemplary worker might be allowed to visit the woman chosen as his wife a few times a year.

Shin's brother was born in 1974 and Shin in 1982. Young children lived with their mothers, who worked from 5 a.m. to midnight. Once they turned 11, children were moved to communal barracks but were allowed to visit their mothers if they excelled at their work.
