Adam, do you think that she would have continued to cover it up if Jeremy hadn't dumped her or asked another girl out? How long do you think she would have kept that up? Remember they had the evidence of the silencer, so she would have had every opportunity to come clean then.
From her testimony it seems to me that she would never have accused him if they hadn't broken up, or do you think that she was on the verge of going to the police anyway?
