PURCELL, Okla. (AP) _ A man accused of killing a 10-year-old girl and nearly severing her head as part of a cannibalistic plot was arraigned Wednesday on a first-degree murder charge.

Kevin Ray Underwood, 26, had a not guilty plea entered on his behalf by the judge. Prosecutors intend to seek the death penalty.

Underwood is accused of smothering Jamie Rose Bolin, his upstairs neighbor in an apartment complex in Purcell, a suburb 40 miles south of Oklahoma City.

The girl was struck in the head, her neck was cut to the bone from ear-to-ear and she was sexually assaulted, according to an autopsy report.

She was reported missing April 12 after failing to return home from a trip to the library. Her nude body was found inside a plastic tub in Underwood's bedroom closet two days later after Underwood raised the suspicions of officers at a police checkpoint and let them search his apartment.

Underwood reportedly confessed that he killed the girl, telling FBI agents: ``Go ahead and arrest me. She is in there. I chopped her up,'' according to a police affidavit.

After his arrest, police and prosecutors revealed grisly details of the crime, saying Underwood raped the girl's corpse and planned to eat her flesh.

A judge later granted Underwood's defense attorney's request for a gag order that prohibits attorneys and law enforcement from discussing the case publicly.
