Oklahoma Beheading Suspect Faces Murder Charges

Police are filing formal murder charges Monday in the beheading of a woman at a food distribution center in an Oklahoma City suburb.

Investigators say Alton Nolen, 30, attacked two women and beheaded one of them Thursday, shortly after he was fired from Vaughan Foods in Moore.

Thus far, the FBI is calling the incident an isolated case of workplace violence. 

That comes decision despite public concerns of Nolen's pride for Muslim extremism.

One of his Facebook post shows a beheading, and quotes the passage from Koran, which reads, "I will instill terror into the hearts of unbelievers; smite ye above their necks and smite all their finger-tips off them."

Nolen faces charges of first-degree murder and assault and battery.
