After reading the media reports and this thread, I've thought about the heart sticker and it's importance to this case. I've come to the conclusion that the heart sticker is not a case-breaker.
While the heart sticker, evidently placed over the duct tape and positioned over Caylee's mouth was a shocking discovery, it's not this case in total. I don't fault the lab worker, trying to lift a fingerprint from the sticker residue, for destroying it in the process. Accidents happen and that duct tape was subjected to being immersed in water for many months.
The defense is making a major issue over the heart sticker residue being destroyed in the process of examination by a trained lab technician. The defense is implying that this was a deliberate destruction of evidence (that in reality only hurt the defense case). But in the long run, the heart sticker won't matter because it's only a small part of the total case.
When you consider.................
*That Casey failed to report her daughter missing for 31 days.
*That Casey lied about a non-existent nanny kidnapping Caylee.
*That Casey lied about having a job.
*That Casey spent those 31 days partying and playing house with TL.
*That Casey's car had a strong odor of human decomposition.
*That a hair from a deceased Caylee was found in Casey's trunk.
*That cadaver dogs hit on 3 different locations in the Anthony yard.
*That cadaver dogs hit on the trunk of Casey's car.
*That computer forensics uncover searches for chloroform, neck-breaking and the use of household items as weapons.
*That Caylee's remains were found around the corner from her home.
*That Caylee's remains were found with items from the Anthony home.
*That Caylee's head was wrapped in duct tape covering her mouth and nose.
*That Casey has never shown any emotion over the loss of Caylee.
When you consider all of the above, and more I didn't include, the heart sticker residue becomes only one small part of the case in total. While it's disappointing that the heart sticker residue was destroyed in the process of lab analysis, it won't change the outcome of the case. The prosecution's case is strong and I'm sure will lead to a conviction.
