 Moore Police Sgt. Jeremy Lewis said his department is waiting until Alton Nolen, 30, regains consciousness to arrest him on unspecified charges. He said Nolen severed the head of 54-year-old Colleen Hufford during Thursday's attack at the Vaughn Foods plant in Moore, a suburb of Oklahoma City. 
 
 "Yes, she was beheaded," Lewis told The Associated Press. 
 
 Lewis said Nolen then stabbed Traci Johnson, 43, a number of times before Mark Vaughan, a reserve sheriff's deputy and the company's chief operating officer, shot him. 
 
 "This was not going to stop if he didn't stop it. It could have gotten a lot worse," Lewis said. 
 
 Lewis said his department asked the FBI to help investigate after co-workers told investigators that Nolen had recently started trying to convert several employees to Islam. He said police asked the FBI to look into Lewis' background because of the nature of the attack, which followed a series of high-profile videotaped beheadings by Islamic State militants. 
 
 In a statement, FBI Special Agent in Charge James E. Finch said the motive for the attack had not been determined, but that there is no reason to believe there was a threat to anyone else. 
 
 A law enforcement official familiar with the investigation told the AP that there was indication that Nolen was a Muslim convert and was trying to convert others to Islam. However, the officials said there is thus far no connection to terrorism and no evidence of any suspicious travelling Nolen might have done. 
 
 The official, who spoke on condition of anonymity because the investigation is ongoing, said Nolen had a Facebook page that was of potential interest to investigators, but that "there doesn't appear to be any nexus to terrorism right now." But the official also said investigators were still looking into Nolen's background. 
 
 Johnson and the suspect were hospitalized and in stable condition Friday, Lewis said. 
 
 According to Oklahoma Department of Corrections records, Nolen served time in prison and is on probation for assault and battery of a police officer. He also was convicted of cocaine possession with the intent to distribute in 2011. 
 
 The records show that Nolen has what appear to be religious tattoos, including one referencing Jesus and one in Arabic that means "peace be with you." 
 
 Lewis said Nolen was fired in a building that houses the company's human resources office, then immediately drove to the entrance of the business. He said he didn't know why Nolen was fired. 
 
 A company spokeswoman said the company was "shocked and deeply saddened" by the attack.

 MOORE, Okla. – Cleveland County District Attorney Greg Mashburn says his office will be ready to file official charges on Alton Nolen Tuesday afternoon. 
 
 MOORE, Okla. – Police are charging a man accused of beheading a woman at Vaughan Foods in Moore, Okla. 
 
 The Moore Police Department says charges filed against Alton Alexander Nolen will include first-degree murder and assault with a deadly weapon. 
 
 Law enforcement will officially file the paperwork in the District Attorney’s office Monday. 
 
 Alton Nolen is also accused of stabbing another woman before being shot himself by an Oklahoma County Sheriff’s Office reserve deputy, Mark Vaughan, who is also the company CEO. 
 
 Nolen, a recent convert to Islam, allegedly attacked a woman Thursday at a Vaughan Foods processing plant, soon after he learned he’d lost his job there. 
 
 Police said he walked into the front office and attacked one of the first people he encountered, Colleen Hufford, 54. 
 
 He severed her head with a knife and then attacked 43-year-old Traci Johnson. 
 
 Johnson has been released from the hospital after being treated for numerous wounds. 
 
 Nolen, 30, was interviewed by investigators on Friday. Police have not revealed what he said. 
 
 The FBI said there are no indications linking Thursday’s attack to terrorism. 
 
 In the Middle East, ISIS, which calls itself the Islamic State, has drawn world attention with videotaped beheadings.

 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 owner 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." 
 
 Authorities say it appears Nolen was attacking employees at random. 
 
 The Medical Examiner confirmed Hufford's cause of death on Friday. 
 
 "Ms. Hufford’s cause of death is decapitation due to multiple sharp force trauma to neck. Manner of death is homicide," said Amy Elliott with the Medical Examiner's Office. 
 
 Johnson was released from the hospital on Saturday. 
 
 Family members say she is "sore" but is doing well. 
 
 The FBI is now looking into Nolen's background after his former co-workers said he tried to convert them to Islam after converting to the religion 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. 
 
 Adam Soltani, the executive director of the Council on American Islamic Relations in Oklahoma, says Nolen's actions are condemned by the Muslim community and his faith should not be connected to this horrific crime. 
 
 "It's really unfortunate that there's a lot of attention on Muslims these days for actions of people who are either part of extremist groups or who have extreme ideas. However, Islam is clear on what it stands for. Islam stands for peace, Islam stands for justice, Islam stands for love for humanity, compassion and mercy. What this gentleman did in Moore, which is inhumane and barbaric, is definitely not a representation of what our faith teaches and we hope and pray that justice will be brought against the perpetrator soon, so that the victims and their families can find some sort of solace in that justice," he said. 
 
 Soltani added that what Nolen did is the "antithesis of every teaching of the Islamic faith." 
 
 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." 
 
 Danielle Katcher, spokesperson from Vaughan Food, added to the company's statement saying: 
 
 "Today, we mourn the loss of an extraordinary member of the Vaughan Foods family, and continue to support both the physical and emotional healing process of all those impacted by this week's violence. 
 
 Our focus remains on the safety and healing of our employees. Since Friday morning, trained counselors have been available to all employees at our Moore facility. This confidential counseling service is providing individualized assistance to those struggling to make sense of this painful experience. 
 
 We will continue to work through this extremely difficult time together, as a team, and are grateful for our strong network of family, friends and co-workers. We would like to thank law enforcement for their swift response, and the community for the continued outpouring of support and condolences." 
 
 The Moore Police Department released the 911 tapes associated with the attack.

 UPDATE 9/26 2:48 p.m.: Sheriff John Whetsel, with the Oklahoma County Sheriff's Office, is speaking out about the deadly attack at a food distribution facility in Moore on Thursday. 
 
 On Friday afternoon, Whetsel released the following statement: 
 
 "Today, my thoughts and prayers are with family and friends of the innocent victim who was murdered and the second innocent victim who was injured in violent knife attacks at Vaughan Foods in Moore, Oklahoma on September 25, 2014. 
 
 These were heinous criminal acts that were ended by the quick response of Oklahoma County Reserve Deputy Sheriff Mark Vaughan. I am extremely proud of the actions of Deputy Vaughan and I am convinced those actions saved the lives of several other employees. Mr. Vaughan, who serves as CEO of Vaughan Foods, was at work and when he was alerted that a man was attacking employees with a knife, Mark didn't hesitate. He quickly responded. 
 
 Mark put an end to the threat by shooting the suspect and saving the life of a second victim who was being actively attacked by the suspect. There is every reason to believe that the lives of untold others were saved who would have been targeted by the suspect if it hadn't been for Deputy Vaughan's actions. 
 
 Mark Vaughan has been with the Oklahoma County Sheriff's Office since June 2010. During that time he has completed the 10-month Reserve Deputy Basic Academy as well as other extensive law enforcement training. Mark is currently assigned to the Patrol Division, is a member of the FAST Team (Fast Action Support Team) and is a highly trained member of the Tactical Team. 
 
 Reserve Deputies serve a very important role in the ability of the Oklahoma County Sheriff's Office to provide law enforcement services and protection to the citizens of Oklahoma County. Reserve Deputies are citizens who attended rigorous law enforcement training and volunteer their time to serve. 
 
 Mark Vaughan is an example of just how significant these men and women are to our citizens. Yesterday lives were saved and a criminal threat ended by the quick and unselfish response of Mark Vaughan. 
 
 Only one word can express my feelings of the actions of Reserve Deputy Mark Vaughan. Without regard to himself or his safety, yesterday Mark Vaughan became a "HERO" while doing the job he was sworn to do- protecting others." 
 
 In addition to Whetsel's statement, the Federal Bureau of Investigation's Oklahoma City Division released its own statement on the incident. 
 
 "The FBI will continue to assist the Moore Police Department and will provide whatever resources are necessary in this investigation. The motive is undetermined at this time and until all the facts have been gathered, we are not in a position to comment further. There is no information currently in our possession to indicate there is any additional threat to the citizens of Oklahoma related to this incident." 

 The man on the 911 call spoke in an urgent voice, the terror still unfolding around him. 
 
 “Shut the door. Shut the door,” the man can be heard saying. 
 
 “What is your emergency?” the dispatcher asks. 
 
 “We have someone attacking someone in the building,” the man says. 
 
 It was 4:05 Thursday, a sunny and warm fall afternoon. 
 
 Alton Alexander Nolen, a 30-year-old ex-convict, had been fired from his job just moments before at Vaughan Foods, a food processing company located at 216 NE 12 in Moore. 
 
 Now, police say, an angered Nolen was taking his vengeance. 
 
 Nolen stormed out of the human resources office, located in a separate building on the southeast side of the property, got in his car and drove the short distance to the processing plant’s main warehouse building, striking another vehicle along the way, police said. He entered the warehouse. 
 
 There he encountered Colleen Hufford, a 54-year-old grandmother, who last year lost her home in the May 20 Moore tornado. A family friend said Hufford had worked in the office at Vaughan Foods for about five years. 
 
 “She was a very kind, forgiving person. Friendly. Little shy, but once she got to know you, she’d talk your leg off,” said family friend Joe Weinzetl. 
 
 Nolen, described by authorities as a practicing Muslim who had recently been trying to convert co-workers, stabbed Hufford and then beheaded her. He used a knife that police said he may have used at his job cutting lettuce and vegetables. 
 
 Next, he turned on another employee, Traci Johnson, 43, of Oklahoma City, slashing her with the same knife. 
 
 From inside a locked office, the caller tells the 911 operator, “We can hear a lot of screaming.” 
 
 “We know that he’s loose. He has stabbed someone.” 
 
 Now another employee got on the line, telling the 911 operator that the attacker had gone through the front office, shipping office and customer service department where he’d stabbed one of the employees. 
 
 By now, three minutes had passed. On the recording of the 911 call, a man, believed to be Nolen, can be heard yelling in the background. 
 
 “Is that him?” the dispatcher asks. “He’s back?” 
 
 “Yeah, it sounds like he’s running around out here,” the caller tells her. 
 
 Moments later, at least two loud pops and a woman’s frightened voice can be heard. 
 
 “And that, that’s a gunshot,” the caller tells the dispatcher. 
 
 Lives saved 
 
 Shortly after Nolen stormed out of the human resources office, an employee had telephoned the on-site office of Mark Vaughan, the company’s chief operating officer, telling Vaughan that Nolen was out of control. 
 
 Vaughan, an Oklahoma County reserve deputy sheriff, arrived at the main building carrying a rifle. There, Vaughan confronted Nolen, then shot and wounded him. 
 
 Authorities say Vaughan’s quick actions saved the life of Johnson and possibly others. 
 
 Moore police responded to what they believed was an active-shooter situation. Once they arrived, they found the victims and evacuated the building. The department’s tactical team then searched the building. 
 
 Sgt. Jeremy Lewis said Moore police responded rapidly and followed procedures “to a T.” 
 
 Both Johnson and Nolen were taken to OU Medical Center Thursday. Authorities said Friday their injuries were not life-threatening. 
 
 Traci Johnson’s grandfather, Carroll McGinnis, of Cushing, said Friday that he heard from other family members that his granddaughter was doing well after Thursday’s attack. 
 
 “I think she’s going to be OK. They cut her on the face and stabbed her a time or two,” McGinnis said. 
 
 He said Johnson is from Cushing but had lived in Oklahoma City for several years. 
 
 He didn’t think she had been working at Vaughan Foods very long. 
 
 Nolen will remain under police guard until doctors approve his release. Once released, he will be taken to the Cleveland County jail, Moore Police Sgt. Lewis said. 
 
 Friday night, the Office of the Chief Medical Examiner issued a statement saying Hufford‘s death was a homicide, the result of decapitation due to multiple sharp force trauma to the neck. 
 
 FBI called 
 
 Moore police have asked the FBI to help investigate the case, including looking into Nolen’s background, in part because of his religious activities. It’s unclear when Nolen converted to Islam, but prison records list his religious affiliation as Islam. 
 
 Nolen has the words “as-salaamu alaikum,” Arabic for “peace be with you,” tattooed on his abdomen, according to Corrections Department records. He has “Jesus Christ” tattooed on his chest, “Judah” on his left arm and praying hands on his right arm. 
 
 On a Facebook page where Nolen calls himself Jah’Keem Yisrael, the main photo shows several heavily armed Islamic fighters. The page also includes several pictures of Osama bin Laden as well as a photo posted March 7 of a beheading. 
 
 James E. Finch, special agent in charge of the FBI’s Oklahoma City office, said a motive for Thursday’s attacks remains undetermined. 
 
 “There is no information currently in our possession to indicate there is any additional threat to the citizens of Oklahoma related to this incident,’’ Finch said. 
 
 The Islamic Council of Oklahoma condemned Thursday’s attacks, saying Oklahoma Muslims are “shocked, horrified and saddened about the loss of innocent life and the injuries.” 
 
 “Workplace and school killings are tragic but are unfortunately becoming more common in America,” the organization said in a prepared statement. “Every loss is felt by family, friends and strangers. Scholars and everyday Muslims maintain that no religious or political goal is ever achieved by these acts.” 
 
 Saad Mohammad, a spokesman for the Islamic Society of Greater Oklahoma City, said leaders of the society’s mosque in northwest Oklahoma City are on alert and taking security precautions to protect against retaliation. 
 
 Mohammad said anti-Muslim sentiment could be heightened due to several recent beheadings of Westerners and other violence being perpetrated overseas by the Islamic extremist group, ISIS. 
 
 “They have this ISIS thing on their minds and now this guy has brought it to America,” Mohammad said. 
 
 On Friday afternoon, a few delivery trucks entered and exited the Vaughan Foods facility. Television satellite trucks and media vehicles parked along the east side of the property but weren’t allowed on site. A few employees could be seen entering and leaving the premises, occasionally standing under a canopy to smoke cigarettes and talk with co-workers. 
 
 The company offered trained counselors to all employees at the Moore facility Friday. In a written release Friday night, the company stated, “We will continue to work through this extremely difficult time together, as a team … We would like to thank law enforcement for their swift response, and the community for the continued outpouring of support and condolences.” 
 
 Criminal past 
 
 Court records show that Nolen has three felony convictions. In the latest case, he pleaded guilty in 2011 to assaulting a highway patrol officer while fleeing arrest. 
 
 It took four law enforcement agencies, two helicopters and 12 hours to apprehend Nolen who fled into a wooded area. The two other convictions involved drug crimes. Corrections Department spokesman Jerry Massie said Nolen had no misconduct record during his time in the Oklahoma prison system. He was discharged in March 2013, but is still on probation. 
 
 On Facebook, Paige Nolen, who is believed to be Alton Nolen’s sister, wrote: “He is alive and doing well. Thanks to all praying warriors out there friends and family. To god be the glory! My bro is alive and just know that the devil is a lie. Please continue prayers.”

– As horrific as yesterday's beheading of an office worker was in Oklahoma, police say they would have had more more victims had a company executive not stepped in to stop the assailant, reports NewsOK. Mark Vaughan, chief operating officer of Vaughan Foods in Moore, also happens to be a reserve deputy sheriff. When he learned of the attack, he left his office, saw a man stabbing a second woman, and shot the assailant twice with a rifle, police say. Suspect Alton Nolen, 30, survived and is under police watch at a hospital. Police say he earlier killed and decapitated 54-year-old Colleen Hufford and was attacking a second employee when he got shot. The second woman suffered non-life-threatening injuries. Nolen had gotten fired from the company moments before the attack occurred. The police have brought in the FBI to help investigate the killing because employees say that Nolen was a Muslim convert who had been trying to convert others to Islam, reports AP. Authorities haven't confirmed that and haven't made a connection between the suspect's religious beliefs and the attack. “It’s really unfortunate that there’s a lot of attention on Muslims these days for actions of people who are either part of extremist groups or who have extreme ideas," the executive director of the Council on American Islamic Relations in Oklahoma tells KFOR-TV. "What this gentleman did in Moore, which is inhumane and barbaric, is definitely not a representation of what our faith teaches." Nolen previously served time in prison for assaulting a police officer, reports AP.
