If I recall correctly it was seized from shelves in her room and categorized as such in the evidence list. Furthermore, considering how this girl writes, don't you think it would have had entries about Tony and scribbles of "Casey Lazzarro" if she had it on her at the time. The girl is dumb, but she's not so dumb that she would have written that and just left it around. Why would she make up a story and leave a confession. She could've been talking about an abortion or a break up for all we know.
Believe me, I think she's guilty and I think there are plenty of smoking guns, but I don't think this is one.
Not to

ther_beatingA_Dead, but we don't yet have answers to the 2 million dollar questions being discussed by WSers:
(1) can LE date that journal entry (using a forensic expert re: the ink, how old the pages are, etc.,
and/or or rep. of the company that manufactured the journal as a fact witness re: when it was manufactured - since if it was first manufactured beginning in 2004 or later, then the '03 can't have anything to do with when the entry was written, etc.) and
(2) can LE prove it was Casey's handwriting (using a forensic handwriting expert)?
Without any such information, all we can do is speculate...and my personal speculation is that Casey is, to use your choice of verbs,
dumb enough to leave it laying around.
:laugh: We already know she was "dumb enough," for example, to write checks out of her friends' check books, to take LE to Universal Studios, walk inside, down the hallway, etc., pretending that she worked there before finally admitting to LE that she did not work there, to assign make-believe names to other peoples' tel. nos. in her cell phone believing that no one would check these out, etc.
