honestly I dont know, I was just speculating on reasons why they might not have enough evidence even if they thought she was involved.
With the insulin, the problems started with the first bag, not the second. experts are saying it was the first bag she had access to and hung, and even though she wasn’t there when they changed to the second bag, it could have been contaminated by the first (via giving set was something they said). The experts seem very certain that the first bag had to be the one that was tampered with but we obviously need to hear it in detail. Won’t be long actually as that was baby F.
Just adding from Wiki below as it explains how the second bag can be contaminated by the first better than I can.
