Junne Koh is not the same person as the boy he killed -- though, for a time, he pretended to be.

Koh, for decades, used the identity of his younger brother Sang, who was 16 when Koh killed him in the fall of 1984.

For taking his brother’s life, Koh was sentenced to prison, lost his U.S. residency and was deported to South Korea. He returned in the early 1990s, posing as his dead brother.
