Okla. woman says she was attacked for looking like Casey Anthony

An Oklahoma woman whose car was rammed as she drove away from the convenience store where she works says she was mistaken for Casey Anthony, KOTV reports.   Sammay Blackwell, 26, says the incident happened in Chouteau, Okla., July 8, days after Anthony was acquitted of murdering her 2-year-old daughter, Caylee, reports the Tulsa TV station.   A woman who had been in the store earlier to buy gas rammed Blackwell's truck with her van as Blackwell was leaving work around 10 p.m.  "I said, 'Oh my God, help me,'" Blackwell tells KOTV's Lacie Lowry.  "She hit me again, causing my vehicle to flip two and a half times, landing on the driver's side, and I just laid there playing dead."  Police arrested Shireen Nalley on charges of assault and battery with a deadly weapon, Lowry reports.  Nalley tells police she was "trying to save the children."  Blackwell, who has a daughter also named Caylee, says that when Nalley came into the store she said, "You look like Casey Anthony,' I'm like, 'OK."   "She said that I was trying to hurt babies, I was killing babies, and she was going to stop it before it happened again," Blackwell recalls.   Anthony is scheduled to be released from a Flordia jail Sunday.
