Pol Pot
In 1997, after a split in the party, Ta Mok seized control of one faction and named himself supreme commander. Pol Pot then fled the Khmer Rouge's northern stronghold, but was later arrested and sentenced to lifelong house arrest. In April 1998, after a new government attack, Ta Mok fled into the forest and took Pol Pot with him. A few days later, on 15 April 1998, Pol Pot died in custody.
