Info on the blanket, and how Misty did on the voice analysis test, when asked about it.:

"T.J. WARD, ADMINISTERED MISTY VOICE ANALYSIS: Hi, Nancy. How are you?
GRACE: I`m good. Mr. Ward, what question that you say she failed concerns you the most? And I have a list of many of your questions right here with me.
WARD: Well, let me tell you exactly what I did. I went through with her and let her ramble and tell me about what happened from February the 9th into February the 10th. The relevant questions that you see on the test results that you have, that you`re looking at, are relevants that I have pulled from the test, from her talking completely through the whole test.
And some of the things that are coming up here --
specifically, if you look about where it says Haleigh -- the blanket smelled like pee, it comes up probably false, and it`s got P-7 and P-9. Well, those two things refer to high rejection incitement, and it`s abnormal emotional, and she`s not --
she`s lying She`s not telling the truth about that.. So that`s one of the things that concerns me."
