I thought Chris Day was with Duke police, not Durham.
Anyway, it's obvious Shelton didn't believe Mangum and was probing her story and that's why she didn't want to talk to him.
Yes, Day is with Duke PD... my mistake. I read another of my posts earlier and I referred to Nifong as "she" twice. There's much I don't understand about Nifong, but doubting his gender is not one of them.
