Something to think about.............Casey isn't very creative in her thinking and lying. She makes up lies based on things that she's familiar with. We've seen her throw out names of people who don't exist, and give their telephone numbers, only to find out those telephone numbers belong to neighbors of the Anthony family.
She stated that she met ZFG through Jeff Hopkins, who had a little boy named Zack, and ZFG was babysat with Zack. While a Jeff Hopkins does exist, he hasn't worked at Universal since 2004 (?) and doesn't have a son named Zack. So, in this case, the person exists, but Casey's description of him is a lie.
Casey bases her lies on real life, changing the names and circumstances to fit her needs, and embellishing her lies in an attempt to make them believable.
Casey has stated that she had a second phone, a Blackberry, that she somehow lost. In the forensic report, it's stated that TonE's cell phone is a Blackberry. I'm sure Casey saw that phone, observed TL using the phone and knows it's functions, and wanted one like it.
So, when she was pressured to come up with an explanation of why she didn't have a telephone number for the nanny who kidnapped Caylee, or for any of the non-existent friends, or telephone numbers of ZFG's relatives, who could vouch for the existence of ZFG, she made up the lie of the lost cell phone, and said it was a Blackberry, based only on the fact that TonE had a Blackberry.
This post should properly belong on the thread about the Blackberry, but in re-reading the computer forensic report linked by belle3, that thought came to mind.
