So I'm rewatching some of the episodes, and had a thought. The anklet that was turned in during season 3 (the one that proved Garrett wasn't "the "killer"), had Alison's blood and someone else's. Assuming the other person is Charles, wouldn't the DNA come up with a partial match since both Alison and Spencer's blood is in the system? (not sure if Charles is related to Spencer, but definitely at least Ali)
