I have always thought the key was to AH's totaled car and that is why she didn't want to retrieve the key from LA. She did not need the key and I assume LA laughed about having taken care of the key because at that point he knew KC had been stealing AH blind and him "taking care" of the key would be one less worry on her mind. I also believe KC may have planned on having the car fixed for herself and that this car is the one referred to in the WW interview that had been wrecked, brought to the repair shop and "smelled like a dead body" that LE received the crime tip from RH the night he was arrested for DUI. I also believe she may have initially drugged Caylee and put her in this car, as it was towed to AL's parking lot 6/14, where from 6/16 on, we know that KC was at TL's everynight, permitting her access to this car wherever it was in his parking lot. The 2.5 hours that LA was gone from the As to TL's to retrieve KC's cell, computer and bag could be explained by LA looking for this car, which may have been located to the bottom left of TL's apartment or the clubhouse. I originally thought LA may have tampered with evidence, or moved Caylee's remains from this car or its trunk, which would explain his 2.5 hour absence. I am considering now that maybe he has been MIA because he may have lawyered up with MN since MN dropped the As as clients, he would be free to represent LA without a conflict of interest and LA is the only one (for now) staying out of the limelight and remaining silent.
Anyone?
