(CNN) — A man suspected of beheading a woman and stabbing another at an Oklahoma workplace had recently been fired, police said Friday.
Nolen recently had been trying to convert co-workers to Islam, Lewis said, citing investigators’ interviews with witnesses. Moore police have asked the FBI to help investigate the man’s background, Lewis said.
Earlier Friday, U.S. law enforcement officials said there were no indications of a link to terrorism.
The incident happened at the Vaughan Foods processing plant in Moore, about 10 miles south of Oklahoma City.
The company’s chief operating officer, Mark Vaughan, shot Nolen, Lewis said; Vaughan is a reserve sheriff’s deputy.
Nolen and the surviving victim were hospitalized. Both are listed in stable condition.
