I think in Nancy's mind, Avery is still guilty of the offense he was jailed for even though DNA exonerated him. I agree with Dr. Phil that these two need a fair retrail. Especially the nephew. He was so easily confused and duped. That was tragic.
After watching the MOAM, I was most confused with how the key wasn't found until the 7th search if the bedroom, no Halbach DNA (blood/sweat/hair that nephew cut) in the bedroom. You saw Avery's home. He's not that clean. And just where was that cop when he called in Halbach license plate?
