IOWA CITY, Iowa (AP) -- The mom of one of the two missing Iowa cousins says she went through a lengthy polygraph test that should prove that she had nothing to do with their disappearance.
Misty Cook-Morrissey said a state agent asked several questions during Monday's test about whether she had anything to do with the abduction of her daughter, 10-year-old Lyric Cook-Morrissey, and niece, 8-year-old Elizabeth Collins.
The girls disappeared July 13 while riding bikes near a lake in Evansdale. The FBI says investigators believe they were abducted but are alive.
Cook-Morrissey says she was told a polygraph test she took last week came back inconclusive but that she passed Monday's test. She says she made peace with investigators, who "can rule me out of their book."
FBI spokeswoman Sandy Breault declined comment.
