totally agree, but the extra prints and wrong size shoes can cause a furrowed brow...
Not only the extra prints, but if Jason was not wearing gloves, which is required if he left prints while committing murder, then he should have had scratches on his hands from when Michelle tried to pull the murderers hands from her neck. She left scratches on her own neck from doing this ... surely she didn't scratch only herlself.
I also have difficulty believing that someone normally wearing a size 12-13 shoe could fit into a size 10 shoe.
