Cleveland County District Attorney Greg Mashburn says he plans to seek the death penalty against a man accused of beheading a woman at an Oklahoma food processing plant.

Mashburn told The Associated Press Wednesday that he discussed his plans with the victim's family and that he could file the paperwork as early as this week.

Prosecutors charged 30-year-old Alton Nolen with first-degree murder in the death of Colleen Hufford, and with two counts of assault. A judge Wednesday ordered Nolen held without bond, and Nolen asked the judge to name a Muslim as his court-appointed lawyer.

Nolen is a recent convert to Islam, and the FBI is investigating because of the nature of the attack, which followed a series of high-profile videotaped beheadings by Islamic State militants in the Middle East.
