Hidden history: Radar probes mass graves from Khmer Rouge era

AFP  |  Prey Veng (Cambodia) 

A man walks gingerly over a small field in rural Cambodia, pushing a lawnmower-like contraption that deploys ground-penetrating to clues of mass graves.

The pilot project is twinning and fieldwork to locate remains of victims of the Khmer Rouge, the ultra-Maoist regime whose quest to build an agrarian utopia from 1975-1979 left an estimated two million Cambodians dead.

Hacked to death, starved, overworked or ravaged by illness, their bodies were dumped in hastily dug pits all over the country. They were thrown in rice paddies, down caves and on the grounds of Buddhist monasteries.

Many of the "Killing Fields" have been logged, providing experts with an estimate of 20,000 mass graves -- which is defined as a pit containing four or more bodies -- throughout the country.

But researchers are now turning to to uncover more details on the existing sites -- such as how many bodies they might contain -- and find new ones.

"This is the first time ever that we have used high-end in to locate mass graves created by the Khmer Rouge," said Pheng Pong-Rasy from the Documentation Center of (DC-Cam), which is overseeing the effort.

He added that DC-Cam decided to start the new search in the eastern province of Prey Veng, where the Khmer Rouge's revolutionary movement had some of its early gains.

"The children must know their own history, what happened in their location," he said.

They began in late October next to buildings at -- specifically plots close to some concrete toilets and an outdoor cafeteria.

The area was once a but the converted it into a place for executions. After the regime fell a school was built nearby.

Students and residents helped clear the overgrown area and operators from SparrowHawk Far East, a new Phnom Penh-based company tapped to test out the idea, walked over it sending signals below that can later be developed into three-dimensional images.

"When there is an object underground or the ground has been disturbed before, if there was a hole dug, it will give off a different signature," told AFP.

"It's good for finding like water pipes and electric pipes, it's good for archeology to find old structures underground," he said. "But it's also been used to find mass graves."

researchers have since the 1990s relied mainly on meticulous interviews with the regime's victims and perpetrators to pinpoint the locations of mass graves.

Elsewhere radar has helped locate indigenous burial sites -- graves from the Spanish Civil War in 1936-1939 and victims of the 1990s conflict in Bosnia.

In September, it also aided in the discovery of at least 166 bodies in the Mexican state of Veracruz, a territory plagued by drug cartels.

Henshaw said the results can bring about a greater understanding of what happened in

"We can try to put a better number on how many victims there actually were," he said.
