Archaeologists have discovered at least 28 early human skeletons in an underground cave in northern Spain. One of the skull, known as Cranium 17, which has two holes above the left eye, belonged to an early human closely related to Neanderthals who lived around 430,000 years ago. Experts believed the lethal wounds identified on a human skull may indicate one of the first cases of murder in human history.
Scientists using modern forensic techniques and analysed the skull that retrieved from site. The truth of what occurred was revealed after researchers pieced together 52 fragments of a near-complete skull. They discovered two holes close together in the skull, above the left eye, caused by two separate impacts from the same object following slightly different trajectories. At first, scientists believed that the injuries occurred when they fell into the bottom of the cave.
