I wondered that too. It was a yahoo article i read earlier. They noted a couple things against avery as well saying he drew a picture of a torture chamber in prison and that his dna was found in the trunk... both irrelevant as far as im concerned considering they had access to his dna anyway. As far as the torture chamber drawing, could have just been him expressing his feelings about how the majority of his life has panned out for him rather than a design of one or just a fantasy. They also noted 2 of 3 calls he made to the woman were blocked... again, not exactly damning evidence. I have ignored phone calls and then gotten a blocked call immediately after.. none of those people murdered me.
I still have alot of questions about the whole thing though.
