A team of archaeologists led by a Birmingham University academic have uncovered up to 700 bodies in a series of mass graves in Bosnia.
The gruesome discoveries were made last week by a group of international experts using satellite imagery, geology and forensic archeology to examine four sites.
Professor John Hunter, also an adviser to the International Commission on Missing Persons (ICMP) which was set up after the Balkan conflict and organised the project, is now preparing to return to eastern Bosnia to locate other mass graves.
Together with two other Birmingham University academics, the mass graves were discovered by assessing changes in the ground's composition-and vegetation.
Mr Hunter, who lives in Dorridge, Solihull, believes there may be more mass graves which have remained undiscovered for a decade.
He said: "It's coming up to almost ten years since the massacre of Srebrenica and that was the point at which something in the order of 30,000 people went missing.
"Our job has been to support the ICMP in trying to find where the graves are and to repatriate the victims.
"The sites were in beautiful hay fields, this wasn't a case of bones sticking out of the ground."
It is hoped the remains will be identified using DNA techniques at ICMP laboratories.
The graves contained between about 50 and 200 bodies, hastily buried following the devastating genocide.
In many cases in Bosnia, the bodies have also been moved from one location to another in order to cover-up evidence of the crime.
Most mass graves found so far have been located based on information supplied by survivors or other witnesses.
Satellite imagery and spectral analysis, which measures changes in the composition of the ground's surface, have recently been used to locate mass graves in Iraq.
Mr Hunter added: "We used non-invasive techniques to identify any disturbances in the ground or changes in vegetation patterns, which can have a very strong geophysical effect.
"We've now found the technology that will help us identify the edges of mass graves quite precisely so when it comes to excavation then we can pin point where they are.
"Also this allows us to prevent any loss of evidence, because the technology enables us to generate computer images of what's in the ground.
"We will continue to process our data which has already told us quite a lot and the ICMP will be able to use it to find future graves, to remove and repatriate the bodies."
Mr Hunter is now preparing to return to Bosnia in the autumn to look at other sites that may contain mass graves.
Because the techniques used are non-invasive, no remains are disturbed before any bodies are exhumed.
Dr Mark Skinner, ICMP's director of forensic sciences, said: "We are not looking to replace the intelligence-based method of finding mass graves but we are seeking techniques that can add to the information we have.
"The perpetrators of these crimes went to great efforts to hide what they did and we need to do everything we can to find the graves."
