WASHINGTON (AP) — Her father was tortured in detention in North Korea and died. Her elder sister went searching for food during the great famine of the 1990s, only to be trafficked to China. Her two younger brothers died of starvation, one of them a baby without milk whose life ebbed away in her arms.

North Korean defector Jin Hye Jo tearfully told her family’s story Wednesday to U.N. investigators during a public hearing in Washington, their latest stop in a globe-trotting effort to probe possible crimes against humanity in North Korea.
