I think ALL of the Anthonys are lying about something.
We know Casey lies, lies, lies.
Brother Lee did not want to take a polygraph and convinced both parents not to do so - after they had already agreed to, according to Leonard Padilla. There would be a REASON Lee did not want to take a polygraph.
We have seen Cindy lie several times. She said she was in constant contact with Casey during the "31 days", but her writings contradicted that statement.
The dead body smell becoming rotted pizza is another lie.
George is the one who surprises me the most. I was shocked when I watched the Greta interview where he described finding the gas cans in Casey's trunk. His demeanor during the telling of that "story" indicated lying, lying, lying.
I now also strongly suspect that his report of seeing Casey and Caylee go out the door with backpacks on June 16th was a deliberate lie.
I also believe that Cindy's statement that she "heard" Casey and Caylee behind Casey's closed bedroom door on the morning of the 16th is another lie.
I know it is bizarre, but - and may God help them - I believe all 3 of the family members are lying to protect Casey.
