Kim Shin-jo was a North Korean soldier and defector who was one of two survivors of the 31-man team of North Korean commandos, known as Unit 124, sent to assassinate the then-president of South Korea and military dictator, Park Chung Hee, in the Blue House raid in January 1968. Kim was captured and during a year-long detention and interrogation divulged information on the raid to the South Korean authorities, before being released. He became a South Korean citizen and spent the rest of his life there.
