A young woman was subjected to a vicious attack after being mistaken for Casey Anthony, RadarOnline.com can report.

Sammay Blackwell - who in a bizarre twist has a daughter named Caylee - was working at a convenience store in Chouteau, Oklahoma when she was mistaken for the troubled 25-year-old.

According to an interview with the terrorized clerk on local station News on 6, Shireen Nalley tried to kill her because she looked like Anthony - who will be released on Sunday after being acquitted of killing her 2-year-old daughter.
