MOORE, OK -- Police say a woman who was killed by a co-worker at a food distribution center in suburban Oklahoma City was beheaded.
Moore Police Sgt. Jeremy Lewis tells ABC News the suspect, Alton Nolen, age 30, beheaded a female victim with a knife was assaulting a second victim when an off-duty Oklahoma County Sheriff's Reserve Deputy working at the facility shot the suspect.
The surviving victim and the suspect were still hospitalized Friday.
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.
Police were called about 4:15 p.m. to reports of a fight inside Vaughan Foods, a food processing plant.
Lewis says officers were told that there had been a shooting.
At this point there is no apparent tie to terrorism.
