While the true purpose of the mass grave(s) has not been verified, the grave site itself has been discovered. In 1971, during plumbing duct installation, a worker found a human skull. According to an article in news paper "Etelä-Saimaa", a mass grave was found. At the time, the site was believed to date back to the Finnish Civil War of 1918, even though the site was not investigated in detail. These findings have since been lost. It is assumed the bones have been destroyed.
