Honestly, I think something is definitely off about their lies about the father. This is a girl who thinks NOTHING of stealing from a friend, a grandparent and parents--all of whom knew she was the thief. Why in the world would she make a conscious decision to not collect child support? And, if the father "died in a car accident," why would this opportunist not collect the SS payments?
Cindy & George have defaulted on credit cards, Cindy was evicted from an apartment--these aren't people who live by strict moral standards. Who cares if the baby's father "doesn't care"--he is legally obligated to financially support his child.
Also, look at the willingness for Cindy to take time out of her harrowing "search" for Caylee to trot down to the AG's office to file a claim of identity theft?
I don't believe ONE THING any member of the Anthony family says.
