Newly released documents show the body of at least one baby found in the garage of a Utah woman accused of killing six of her newborns over a decade was covered in a chemical that smelled like iodine.

Documents made public Friday reveal the husband of 39-year-old Megan Huntsman found the first body April 12 after opening a box covered in plastic wrap. Darren West told police he discovered a baby inside, with a strong chemical odor emanating from the plastic bag it was in.

Police in Pleasant Grove later discovered six other dead babies after obtaining a search warrant for the house.

Huntsman was charged this week with six counts of first-degree murder. She has not entered a plea.
