They pieced together some evidence of when and how the mass killings had taken place from clues such as the bodies’ states of decay, the times and dates on their self-winding watches, INTERFOTO/AKG-IMAGES and the characteristic patterns of damage caused to skulls by bullets. Analysis of the colours and textures of soils pointed to where some of the bones had first been dumped. For example, chips of glass indicated burial near a glass factory in the area. The task of identifying the bones was exquisitely difficult. The bulldozers had broken up the bodies, and the pieces had been mixed up in the dumper trucks transporting them to new burial sites. DNA analysis of each bone was the only possible method of conclusive identifica- tion, so the ICMP set up its lab.
