Pleasant Grove Police Capt. Mike Roberts said Tuesday that the results from the FBI also show that five of the babies were girls and two were boys. Roberts says all seven were full term.
The 39-year-old Megan Huntsman is charged with six counts of first-degree murder. She told officers that she strangled or suffocated six of the babies from 1996 to 2006. Huntsman said one infant found was stillborn.
Huntsman's estranged husband, Darren West, lived with her during the decade the babies were killed before going to federal prison on drug charges from 2006 until January. He is not a suspect.
