PHNOM PENH—Ta Mok, the 82-year-old former Khmer Rouge commander whose actions earned him the nickname “The Butcher,” has died at a military hospital in the Cambodian capital.
Ta Mok, who died Friday, was being treated for high blood pressure, tuberculosis, and breathing complications, his lawyer, Benson Samay, said.
Widely known as a ruthless enforcer for Khmer Rouge leader Pol Pot, Ta Mok remained powerful for years after Vietnam toppled the Khmer Rouge. He controlled northern areas of the Khmer Rouge's remaining territory from his base at Anlong Veng.
After a split in the party, he declared himself supreme commander in 1997 and was detaining Pol Pot when he died.
Earlier this month, officials were sworn in for a long-awaited trial of those blamed for the deaths of an estimated 1.7 million people under the Khmer Rouge from 1975-79. Ta Mok could have provided key testimony against other defendants.
Only Ta Mok and former prison commander Kaing Khek Iev, also known as Duch, were in custody ahead of the trial, and many people fear that more defendants—all of whom are elderly—may die before they can be tried.
On July 13, his lawyer summoned the media to report that Ta Mok had lapsed into a coma.
His illness did “not coincide with the operations of the Khmer Rouge tribunal,” he said, adding that his client suffered “a long, chronic, old-age disease, because he was already 82 years old.”
He also blamed “the carelessness of those responsible who let Ta Mok become so severely ill,” local media reported. Ta Mok was a top commander of the army of Democratic Kampuchea, generally known as the Khmer Rouge regime.
He was arrested March 6, 1999 in Anlong Veng district in the northwestern part of Cambodia and detained at the Military Prison in Phnom Penh awaiting trial by a unique tribunal.
The tribunal, formally called Extraordinary Chambers in the Courts of Cambodia, is described as a "hybrid court" operating according to Cambodian laws but staffed by judges, prosecutors, and others from a number of countries in addition to Cambodians.
Ta Mok is one of the Khmer Rouge leaders profiled in Seven Candidates for Prosecution by Steve Heder, which lays out the cases against seven top leaders.
Heder cites "significant evidence that Ta Mok…played a central role in implementing the Communist Party’s execution policies.”
According to research documents published by the Documentation Center of Cambodia (DC-CAM), Ta Mok was born with the original name of Ung Choeun.
