In June 1992, the first mass grave was discovered at the Sutina cemetery, containing the remains of 26 civilians from Mostar. Two months later, in August 1992, another mass grave was uncovered at the Uborak municipal landfill, some five kilometres from Sutina. It contained the remains of 88 war civilians. Most of them had been shot in the head with automatic weapons.

The exhumations were carried out as the war continued. Police inspector Drazen Pazin, who was involved in the process of exhumation at the Uborak landfill, said there were difficulties digging up the bodies because of constant shelling from positions held by the Yugoslav People’s Army (JNA).

Earlier in the summer of 1992, Bosniak and Croats were taken from various villages north of Mostar, and from the Carina and Zalik neighbourhoods, by Serb fighters. The captives were detained in locker rooms at the FK Lokomotiva Mostar football stadium in Vrapcici, and taken for questioning in buildings at the Sutina cemetrey, where they were also held in detention. 

All 114 victims buried at Uborak and Sutina were killed on June 13, 1992. The perpetrators were members of the JNA, reservists and members of paramilitary groups, assisted by local Serbs, according to trial witnesses. 

There is now a memorial plaque honouring the victims at the Uborak landfill. 

No one has yet been convicted of the killings of the Bosniaks and Croats who were buried at Uborak and Sutina.

At the time of the crime, the JNA units were commanded by general Momcilo Perisic. Although he was prosecuted in The Hague, Uborak was not included in the indictment. The Hague Tribunal established in its verdict in the trial of Serbian Radical Party leader Vojislav Seselj that in April and June 1992, members of the Serb-led Territorial Defence, paramilitary units and fighters known as Seseljevci (‘Seselj’s Men’) tortured and mistreated prisoners at the Uborak landfill, the Sutina cemetery and the FK Lokomotiva Mostar stadium.
