Good Guy With Gun Stopped Killer in Oklahoma—Called 'Hero' by Police

Mark Vaughn, an off-duty officer who also serves as chief operating
officer of Vaughan Foods processing center in Moore, Oklahoma, shot Alton Nolen after Nolen beheaded a staffer at the food distribution center and proceeded to stab another worker. According to KFOR:

Officials with the Moore Police Department say the FBI is now involved in the investigation related to a brutal attack of workers at a food distribution plant.

Sgt. Jeremy Lewis says the alleged suspect, 30-year-old Alton Nolen had just been fired when he drove to the front of the business, hit a vehicle and walked inside.

He walked into the front office area where he met 54-year-old Colleen Hufford and began attacking her with a knife.

Sgt. Lewis confirms the type of knife used in the attack is the same kind used at the plant.

Lewis confirms that Hufford was stabbed several times and that Nolen “severed her head.”

At that point, Lewis claims Nolen met 43-year-old Traci Johnson and began attacking her with the same knife.

Officials say at that point, Mark Vaughan, an Oklahoma County reserve deputy and a former CEO of the business, shot him as he was actively stabbing Johnson.

“He’s, obviously, a hero in this situation,” Sgt. Lewis said, referring to Vaughan. “It could have gotten a lot worse.”

BearingArms.com notes that Vaughan reportedly used a rifle to stop Nolen. According to Sgt. Lewis,investigators say that witnesses said that Nolen had attempted to convert former fellow  employees to Islam. KFOR reports that many as 300 workers inside of the warehouse at the time of the incident.
