Police say a woman who was killed by a co-worker at a food distribution center in suburban Oklahoma City yesterday was beheaded. Moore Police Sgt. Jeremy Lewis says the woman, who has not been identified, was beheaded by a man who attacked her and another woman at Vaughan Foods in Moore around 4:15pm. An off-duty officer who was working at the business shot the suspect. The surviving victim and the suspect were still hospitalized today. The motive for the attack was unclear, but Lewis said the suspect and the victims were apparently not involved with each other outside of their work at the business. (More decapitation stories.)
