It looks like Casey Anthony will need a pretty good disguise. Sammy Blackwell, a Chouteau, Oklahoma, woman who looks somewhat similar to Casey Anthony, was attacked by a woman who appears to have mistaken her for the woman acquitted of murdering her child. The attacker bought gas from Blackwell's convenience store and waited outside for Blackwell to leave work. As Blackwell backed out, her car was rammed by the attacker's minivan and flipped over twice. Blackwell says the police told her that her attacker "said that I was trying to hurt babies [that] I was killing babies, and she was going to stop me before it happened again."
