And that’s exactly what he did.

OKLAHOMA CITY (AP) — Alton Nolen told relatives after his release from prison on drug and assault charges last year that he wanted to focus on getting his life in order.

But postings on the Facebook page of the 30-year-old Nolen, suspected of beheading a woman at an Oklahoma food distribution center, suggest that shortly after his release in March 2013, he became more interested in spreading the message of his newfound Islamic faith.

“I spoke to him once he was released, and when we spoke, there was nothing of the sort,” said Nolen’s cousin, James Fulsom, 29, of Fort Worth, Texas. “I don’t believe he was converted (to Islam) in prison.”

Cleveland County District Attorney Greg Mashburn said he expects to charge Nolen on Tuesday with first-degree murder in Thursday’s killing of 54-year-old Colleen Hufford at the Vaughan Foods plant in Moore, an Oklahoma City suburb.

Moore Police Sgt. Jeremy Lewis said Nolen, who had just been fired from the company, walked into the facility’s administrative office and attacked Hufford with a large knife, eventually severing her head. Nolen then repeatedly stabbed 43-year-old Traci Johnson before he was shot by Mark Vaughan, a reserve sheriff’s deputy and the company’s chief operating officer, police said.
