From KFOR: MOORE, Okla. – 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 a hero in this situation,” Sgt. Lewis said, referring to Vaughan. “It could have gotten a lot worse.”

Authorities say it appears Nolen was attacking employees at random.

Johnson is in stable condition at a local hospital, recovering from her injuries.

The FBI is now looking into Nolen’s background after his former co-workers said he tried to convert them to Islam after recently converting himself.

Lewis says the FBI is working in conjunction with the Moore Police Department, especially when it comes to the religious aspect of the case.

At this time, it is not known if the suspect’s beliefs played a role in the attack.

Employees are back at work today.

Vaughan Foods released the following statement about the attack:

“On behalf of everyone at Vaughan Foods, we are shocked and deeply saddened by the events of today. Our thoughts and prayers go out to the families and friends of the team member we lost and all those affected. Our focus is on the safety and well-being of our employees. We will provide counseling and support for our team members and support each other through this difficult time. We are working with authorities on this active investigation and ask that you direct your questions to local law enforcement.
