One morning in July 2005, Amy Mundorff rode into the Bosnian countryside, tagging along with a team from the International Commission on Missing Persons. The roads wound past forests, farmland and villages. The group stopped near a field in a hilly area on the outskirts of a village to meet an informant. From the gestures and the translator’s comments, Mundorff understood that the ground beneath the field might hold bodies.

The war in Bosnia-Herzegovina had ended 10 years earlier, but thousands of people remained missing, many presumed buried in hidden graves scattered across the country. Mundorff, a forensic anthropologist, wanted to learn how the team excavated and exhumed graves, and then sorted and identified co-mingled human remains — her area of expertise.

Backhoes scraped away the topsoil, peeling back the earth inches at a time. “They just dug and dug and dug,” recalls Mundorff. Once in a while, the machinery operators would stop and call over an investigator. “It was never anything human. There were roots, animals bones, rocks . . . but there were no graves,” says Mundorff. By the end of the day, the entire hillside had been dug up, and the team found nothing.

Witness and survivor testimonies remain the most reliable way to locate hidden graves, but the approach is not foolproof. Many of the conflicts under investigation occurred years ago. Elderly witnesses may have fading memories that offer incomplete or incorrect accounts of atrocities. Sometimes the geography of a place changes. Roads get rerouted, forests are cleared, and the edges of villages expand.
