Workers restore artwork inside a Maya structure at the el Mirador archaeological site in the Peten jungle, Guatemala August 25, 2009. Archaeologists are using blood samples and DNA tests to prove that the final inhabitants of an ancient Maya city were finished off by their enemies in a bloody battle at the top of one of their highest pyramids.
