Alone (hypothesis only)- Iirc prior to having a meal at the Cheesecake factory, a few days before Caylee disappeared, a female friend or ex girlfriend of Tony's happened by at the mall and Casey didn't like this one bit. Casey was the cheater, Casey controlled everything and everyone, how dare this happen. Tony teasing Casey about not returning from New York is another example of how this new relationship played on Casey's insecurities. Casey was doing the female thing and projecting herself into the future, practising writing Casey Lazzarro while poor Tony was doing what guys do and playing it one day at a time with no clue that this girl he's seeing has a disfunctional background and a serious screw loose. Stringing along a few other guys at the same time as Tony did nothing to appease Casey imo. So here's Casey on the 16th, a few days have passed since Mall Millenia but her inner jealous rage hasn't abated in spite of burning up the phone lines with Tony into the wee hours from the 15th to the 16th.
Meantime Caylees become an inconvenience for the first time in her life in recent times. The little snothead. A possible liability too, perhaps she'll expose her mothers lies. Cindy's quickly growing tired of the BS from Casey, argh, there's so many financial woes and too much drama. Amidst this Casey has to put up with George, grr, Casey hasn't thought much of her father since she became a teenager. Nothings going right for Casey, she can only stall her friend Amy re her lies about moving in for so long, blame her parents for that falling through. Man, it's now early afternoon and Casey has been working almost all night and all day, her lying is a fulltime job. Add to that the closest thing to a real job she's had in recent times, a shots girl at Fusian nightclub with view to management at some stage and the responsibility is heaping upon Casey. So many invites to send via Myspace and Facebook, she's been hard at it all morning trying to promote the place. She's still got to call Amy later in the day and Jesse to keep stringing him along in between sweet talking Tony. Geez, a psychos job is never done.
Casey needs a break, maybe it would be nice to go hang with Tony for the night, erase other females from his mind, if only her Mother would babysit. Problem is Cindy has a real job and has raised her own kids and wants Casey to do the same, she won't allow Casey to go off every night and leave Caylee behind. Casey's stress levels are through the roof, she's been juggling all these balls up in the air and when her child adds to the pressure that day Casey snaps. It may have been pizza that Caylee wanted, Casey never minded in the past getting the little girl some food but now much more is at stake, Anthony Rusciano couldn't be bothered with Casey because of Caylee, enter Tony who not only lived in a Bach pad but drove Casey crazy with his non committal attitude. Shut up Caylee! F you and the pizza. With no real planning Casey grabs the nearest thing to put over Caylees mouth to no end, before stalking off to the garage to grab the duct tape because she means business. The little girl is crying and doesn't follow her like she usually would, she understands her mum is upset, tired, and she gasps at Caseys rage when she returns with the tape. Perhaps her final breath. I don't want to imagine the scene that ensued, suffice to say it was sufficient to ensure that Caylee was silenced forever and Casey got to spend until 2.30pm the next day at Tony's. What a relief for Casey, she could now cut some ties with her family, see how far she could take things with Tony, have fun spending Amy's money and the huge burden of Caylee ruining her fun is over. The good old days are back. It's all about Casey once more. Time to get a tattoo to celebrate this beautiful life. What a shame there was another female Anthn'y family member waiting in the wings, ready to burst Caseys bubble. All moo.
