History

To accommodate the victims of purges that were important enough for the attention of the Khmer Rouge, a new detention center was planned in the building that was formerly known as Tuol Svay Prey High School, named after a royal ancestor of King Norodom Sihanouk. The five buildings of the complex were converted in March or April 1976 into a prison and an interrogation center. Other buildings in town had already been used as prison S-21. The Khmer Rouge renamed the complex "Security Prison 21" (S-21) and construction began to adapt the prison for the inmates: the buildings were enclosed in electrified barbed wire, the classrooms converted into tiny prison and torture chambers, and all windows were covered with iron bars and barbed wire to prevent escapes and suicides.

From 1976 to 1979, an estimated 20,000 people were imprisoned at Tuol Sleng (the precise number is unknown). At any one time, the prison held between 1,000 and 1,500 prisoners. They were repeatedly tortured and coerced into naming family members and close associates, who were in turn arrested, tortured and killed. In the early months of S-21's existence, most of the victims were from the previous Lon Nol regime and included soldiers, government officials, as well as academics, doctors, teachers, students, factory workers, monks, engineers, etc. Later, the party leadership's paranoia turned on its own ranks and purges throughout the country saw thousands of party activists and their families brought to Tuol Sleng and murdered.[5] Those arrested included some of the highest ranking politicians such as Khoy Thoun, Vorn Vet and Hu Nim. Although the official reason for their arrest was "espionage", these men may have been viewed by Khmer Rouge leader Pol Pot as potential leaders of a coup against him. Prisoners' families were sometimes brought en masse to be interrogated and later executed at the Choeung Ek extermination center.

In 1979, the prison was uncovered by the invading Vietnamese army. At some point between 1979 and 1980 the prison was reopened by the government of the People's Republic of Kampuchea as a historical museum memorializing the actions of the Khmer Rouge regime.

Routine

Upon arrival at the prison, prisoners were photographed and required to give detailed autobiographies, beginning with their childhood and ending with their arrest. After that, they were forced to strip to their underwear, and their possessions were confiscated. The prisoners were then taken to their cells. Those taken to the smaller cells were shackled to the walls or the concrete floor. Those who were held in the large mass cells were collectively shackled to long pieces of iron bar. The shackles were fixed to alternating bars; the prisoners slept with their heads in opposite directions. They slept on the floor without mats, mosquito nets, or blankets. They were forbidden to talk to each other.

The day began in the prison at 4:30 a.m. when prisoners were ordered to strip for inspection. The guards checked to see if the shackles were loose or if the prisoners had hidden objects they could use to commit suicide. Over the years, several prisoners managed to kill themselves, so the guards were very careful in checking the shackles and cells. The prisoners received four small spoonfuls of rice porridge and a watery soup of leaves twice a day. Drinking water without asking the guards for permission resulted in serious beatings. The inmates were hosed down every four days.

The prison had very strict regulations, and severe beatings were inflicted upon any prisoner who disobeyed. Almost every action had to be approved by one of the prison's guards. The prisoners were sometimes forced to eat human feces and drink human urine. The unhygienic living conditions in the prison caused skin diseases, lice, rashes, ringworm and other ailments. The prison's medical staff were untrained and offered treatment only to sustain prisoners' lives after they had been injured during interrogation. When prisoners were taken from one place to another for interrogation, they were blindfolded. Guards and prisoners were not allowed to converse. Moreover, within the prison, people who were in different groups were not allowed to have contact with one another.

Torture and extermination

Cabinets filled with human skulls

Most prisoners at S-21 were held there for two to three months. Within two or three days after they were brought to S-21, all prisoners were taken for interrogation. The torture system at Tuol Sleng was designed to make prisoners confess to whatever crimes they were charged with by their captors. Prisoners were routinely beaten and tortured with electric shocks, searing hot metal instruments and hanging, as well as through the use of various other devices. Some prisoners were cut with knives or suffocated with plastic bags. Other methods for generating confessions included pulling out fingernails while pouring alcohol on the wounds, holding prisoners' heads under water, and the use of the waterboarding technique. Women were sometimes raped by the interrogators, even though sexual abuse was against Democratic Kampuchea (DK) policy. The perpetrators who were found out were executed. Although many prisoners died from this kind of abuse, killing them outright was discouraged, since the Khmer Rouge needed their confessions. The "Medical Unit" at Tuol Sleng, however, did kill at least 100 prisoners by bleeding them to death. It is proven that medical experiments were performed on certain prisoners. There is clear evidence that patients in Cambodia were sliced open and had organs removed with no anesthetic. The camp's director, Kang Kek Iew, has acknowledged that "live prisoners were used for surgical study and training. Draining blood was also done.

In their confessions, the prisoners were asked to describe their personal background. If they were party members, they had to say when they joined the revolution and describe their work assignments in DK. Then the prisoners would relate their supposed treasonous activities in chronological order. The third section of the confession text described prisoners' thwarted conspiracies and supposed treasonous conversations. At the end, the confessions would list a string of traitors who were the prisoners' friends, colleagues, or acquaintances. Some lists contained over a hundred names. People whose names were in the confession list were often called in for interrogation.

Typical confessions ran into thousands of words in which the prisoner would interweave true events in their lives with imaginary accounts of their espionage activities for the CIA, the KGB, or Vietnam. Physical torture was combined with sleep deprivation and deliberate neglect of the prisoners. The torture implements are on display in the museum. It is believed that the vast majority of prisoners were innocent of the charges against them and that the torture produced false confessions.

For the first year of S-21's existence, corpses were buried near the prison. However, by the end of 1976, cadres ran out of burial spaces, and the prisoner and family members were taken to the Boeung Choeung Ek ("Crow's Feet Pond") extermination centre, fifteen kilometers from Phnom Penh.[12] There, they were killed by a group of teenagers led by a Comrade Teng, being battered to death with iron bars, pickaxes, machetes and many other makeshift weapons owing to the scarcity and cost of ammunition. After the prisoners were executed, the soldiers who had accompanied them from S-21 buried them in graves that held between as few as 6 and as many as 100 bodies.

Non-Cambodian prisoners

Almost all non-Cambodians had left the country by early May 1975, following an overland evacuation of the French Embassy in trucks. The few who remained were seen as a security risk. Though most of the foreign victims were either Vietnamese or Thai, a number of Western prisoners, many picked up at sea by Khmer Rouge patrol boats, also passed through S-21 between April 1976 and December 1978. No foreign prisoners survived captivity in S-21.

Even though the vast majority of the victims were Cambodian, some were foreigners, including 488 Vietnamese, 31 Thai, four French, two Americans, two Australians, one Laotian, one Arab, one Briton, one Canadian, one New Zealander, and one Indonesian. Khmers of Indian and Pakistani descent were also victims.

Two Franco-Vietnamese brothers named Rovin and Harad Bernard were detained in April 1976 after they were transferred from Siem Reap, where they had worked tending cattle. Another Frenchman named Andre Gaston Courtigne, a 30-year-old clerk and typist at the French embassy, was arrested the same month along with his Khmer wife in Siem Reap.

It is possible that a handful of French nationals who went missing after the 1975 evacuation of Phnom Penh also passed through S-21. Two Americans were captured under similar circumstances. James Clark and Lance McNamara in April 1978 were sailing when their boat drifted off course and sailed into Cambodian waters. They were arrested by Khmer patrol boats, taken ashore, where they were blindfolded, placed on trucks, and taken to the then-deserted Phnom Penh.

Twenty-six-year-old John D. Dewhirst, a British tourist, was one of the youngest foreigners to die in the prison. He was sailing with his New Zealand companion, Kerry Hamill, and their Canadian friend Stuart Glass when their boat drifted into Cambodian territory and was intercepted by Khmer patrol boats on August 13, 1978. Glass was killed during the arrest, while Dewhirst and Hamill were captured, blindfolded, and taken to shore. Both were executed after having been tortured for several months at Tuol Sleng. Witnesses reported that a foreigner was burned alive; initially, it was suggested that this might have been John Dewhirst, but a survivor would later identify Kerry Hamill as the victim of this particular act of brutality. Robert Hamill, his brother and a champion Atlantic rower, would years later make a documentary, Brother Number One, about his brother's incarceration.

One of the last foreign prisoners to die was 29-year-old American Michael S. Deeds, who was captured with his friend Christopher E. DeLance on November 24, 1978, while sailing from Singapore to Hawaii. His confession was signed a week before the Vietnamese army invaded Cambodia and ousted the Khmer Rouge. In 1989, Deeds's brother, Karl Deeds, traveled to Cambodia in attempts to find his brother's remains, but was unsuccessful. On September 3, 2012, DeLance's photograph was identified among the caches of inmate portraits.

As of 1999, there were a total of 79 foreign victims on record, but former Tuol Sleng Khmer Rouge photographer Nim Im claims that the records are not complete. On top of that, there is also an eyewitness account of a Filipino, a Cuban and a Swiss who passed through the prison, though no official records are shown.

Survivors

Out of an estimated 20,000 people imprisoned at Tuol Sleng, there were only twelve known survivors: seven adults and five children. One child died shortly after the liberation.  As of mid-September 2011, only three of the adults and four children are thought to still be alive: Chum Mey, Bou Meng, and Chim Meth. All three said they were kept alive because they had skills their captors judged to be useful. Bou Meng, whose wife was killed in the prison, is an artist. Chum Mey was kept alive because of his skills in repairing machinery. Chim Meth was held in S-21 for two weeks and transferred to the nearby Prey Sar prison. She may have been spared because she was from Stoeung district in Kampong Thom where Comrade Duch was born. She intentionally distinguished herself by emphasising her provincial accent during her interrogations. Vann Nath, who was spared because of his ability to paint, died on September 5, 2011. Norng Chan Phal, one of the surviving children, published his story in 2018.

The Documentation Center of Cambodia has recently estimated that, in fact, at least 179 prisoners were freed from S-21 between 1975 and 1979 and approximately 23 prisoners (including five children, two of them siblings Norng Chanphal and Norng Chanly) survived when the prison was liberated in January 1979. One child died shortly thereafter.[12] Of the 179 prisoners who were released, most disappeared and only a few are known to have survived after 1979. It was found that at least 60 persons (out of the DC Cam list) who are listed as having survived were first released but later rearrested and executed.
