South Australian Police say a post-mortem examination will be carried out today on the body of a man found buried in a forest south of Adelaide. Police are investigating the discovery of the body in a shallow grave in the Kuitpo Forest. They say a person walking in the area alerted them after finding a blood-stained shirt nearby. Police say the identity of the man cannot be confirmed until they get the results of the post-mortem. It is understood they are investigating whether it is 45-year old Michael Varehov from Mawson Lakes. Police says he is missing in suspicious circumstances and believe his disappearance is linked to an assault at suburban Beaumont in Adelaide. A man has since been charged with assault. Police say a Peugeot sedan connected to Mr Varehov's disappearance was also found last night, burned out at the nearby town of Myponga.
