I can see Annie providing alot of information on what Casey was really like...not the fantasy version you get from her family. I could also see there being a link to Xanax and possibly even the knowledge that the nanny wasn't real..as stated by previous posters. But what I am struggling with is why LE has withheld her interview. They have released alot of info that has been pretty damaging so far...so why hold back on Annie? What does she know that they don't want released?
