Update: added video with the Moore, OK police press conference which confirms the beheading.
There's some horrifying news coming to us from Moore, Oklahoma, where a 54-year-old woman was beheaded by an assailant at work. Initial reports suggest that the attacker had recently been fired and returned to the food processing plant where he worked. There, he used one of the knives in the facility to behead one of his former coworkers before moving on to stab another.
