Searching for N.Korea's Missing

The digital detectives picking up the pieces of a missing trail to find their loved ones

As the Korean War ended in the 1950s, the North Korean army fell back across the border. During this final retreat, thousands of people from South Korea were kidnapped or told of a better life in the North. Many were never seen again.

While some managed to escape back to the South, others had no choice and remained behind - even if it meant splitting up from their family members. Today, a handful of activists, defectors, and loved ones dedicate their lives to find and bring back those that are missing.
