There was something I read where one of the officers said they were suspicious about Julie earlier on ( in other words they thought she might be involved ) and I do still wonder if they in a roundabout way did to try through her to try and get some information and she started questioning Jeremy.
But of course I don't know for sure - but I still feel her testimony does not add up and I think she could be a drama queen . I have very niggling doubts about her evidence.
