OKLAHOMA CITY `— A man who was shot after authorities say he beheaded one woman and attacked another at an Oklahoma food processing plant from which he had just been fired has regained consciousness and was interviewed by detectives Saturday.

Alton Nolen, 30, remains hospitalized in stable condition after Thursday’s attack at the Vaughan Foods plant in the Oklahoma City suburb of Moore, Police Sgt. Jeremy Lewis said. He said that Nolen will be charged Monday with first-degree murder and assault and battery with a deadly weapon and that he may also face federal charges.

Meanwhile, a spokesman for an Oklahoma City Islamic group said Saturday that Nolen was a frequent worshipper at a mosque the group maintains and that he remembers the suspect as “a little weird.”

“He was a nice, quiet, low-key guy,” said Saad Mohammed, director of information for the Islamic Society of Greater Oklahoma City. “He acted a little odd,” Mohammed said, though he added that Nolen’s behavior never raised any “red flags.”

Mohammed said Nolen began worshipping at one of the group’s mosques in May.
