Archaeologists have revealed a 1300-year-old Chinese murder mystery in a tomb raiders' shaft. While excavating the tomb at Shiyanzi cemetery, in China’s north-central Ningxia region, the team discovered the skeleton of a young man riddled with stab wounds. The man, who the team estimate was around 25-years-old, was thought to have been still alive when he was thrown into the tomb raiders' shaft and left to die.
