Scientists at the Denver Museum of Nature and Science have a new story to tell about their two resident female mummies.

Researcher Michele Koons, who's curator of archaeology at the museum, told Colorado Matters host Ryan Warner that the mummies have long been called "Rich Mummy" and "Poor Mummy" because scientists believed the women came from different economic backgrounds. 

But new, advanced technology, including a CAT scan that allows three-dimensional modeling, reveals the difference between the two mummies is more about their place in the history of Egyptian mummification than about their economic status.
