Investigators are reconstructing a mysterious decade from Megan Huntsman's life as they try to figure out how she concealed seven pregnancies before allegedly strangling or suffocating her newborns.

Utah investigators are examining DNA from the babies to determine who the parents are, studying the bones to find out how long ago the babies died and interrogating family members and talking to neighbors in pursuit of clues about how she did it.

The 39-year-old Huntsman acknowledged to police that she killed the babies and put them in plastic bags and then packed them inside boxes in the garage of her home south of Salt Lake City. What's not clear is why.

Huntsman was arrested Sunday on six counts of murder. She is in jail on $6 million bail.
