Tollund Man: Peaceful in the Peat

S1 E5: Near Silkeborg, Denmark, peat diggers uncover a human head and authorities quickly work to identify who it is, possibly relating it to a missing boy in the area. But a keen police officer reveals the body is much older than the current missing person and calls the museum to investigate. What is discovered during the excavation is a perfectly preserved person, posed most interestingly and peacefully. Could this positioning be a clue to how and why he was murdered?
