Spanish cave reveals ancient murder mystery

Scientists working in a Spanish cave may have stumbled across the world's oldest murder mystery.

A fossilized skull belonging to a primitive member of the Neanderthal lineage shows two fractures inflicted by the same weapon.

The 430,000-year-old skull was found with the remains of 30 individuals in an apparent funerary site at the bottom of a 13-meter shaft in the bleak-sounding Sima de los Huesos, or Pit of the Bones, in the Atapuerca mountains.
