This list of unsolved murders includes notable cases where victims have been murdered under unknown circumstances.
Before 1800
The Gebelein Man (18–20), one of six naturally mummified bodies dating back to 3400 BC found in 1896 in Egypt, is suspected to have been murdered, because a 2012 CAT scan determined that there were puncture wounds on his body. As with most things surrounding the mummies' lives, his murder remains a mystery. Ötzi, also called the Iceman, is the well-preserved natural mummy of a man who lived between 3400 and 3100 BCE. The mummy was found in September 1991 in the Ötztal Alps. The cause of death remained uncertain until 10 years after the discovery of the body. Currently, it is believed that Ötzi bled to death after being hit by an arrow which shattered the scapula and damaged nerves and blood vessels before lodging near the lung. Bog bodies are a numerous class of men and women which had been violently killed from prehistoric times into the Middle Ages. The victims had subsequently been dumped in swamps where they were naturally mummified. It is unclear whether the bog bodies were sacrificed, executed, or murdered. Notable examples include the Bocksten Man, the Tollund Man, the Lindow Man and the Lindow Woman.
