Archeologists in Peru have discovered the remains of what they believe is the first person in the Western hemisphere to be killed by a gunshot.

Archeologist Guillermo Cock says his team found a 500-year-old skull with two round holes in it, in an Incan cemetery outside Lima in 2004.

Using an electronic microscope at a U.S. lab at the University of New Haven's Henry C. Lee Institute of Forensic Science, scientists found traces of metal from a musket ball on the skull.

Cock says the skull was found in a shallow grave with about 72 other bodies, some of which showed signs of terrible violence by crude weapons.

Cock says the victims likely were killed in a battle with Spanish conquistadors and their local allies.
