TYLER, Texas — A man killed his girlfriend, then filleted and cooked parts of her body before calling police to tell them what he was doing, authorities said yesterday.

Christopher Lee McCuin, 25, called 911 on Saturday and told an emergency dispatcher he had killed Jana Shearer, 21, and was boiling her body parts at his mother’s home, Sheriff J.B. Smith of Smith County said.

When authorities arrived at the home, they found Shearer’s mutilated body, one ear boiling in a pot of water on the stove and a fork sticking out of some human flesh sitting on a plate on the kitchen table.

Authorities said it was unclear if Mr. McCuin consumed any part of Shearer’s body. “We cannot prove that he did,” Mr. Smith told the Associated Press. “He was either going to, had been, or led us to think that he was doing it.”

Authorities believe Shearer, 21, was abducted from her home Friday night and killed. Her death and mutilation was apparently the beginning of a crime spree that also included Mr. McCuin allegedly stabbing the boyfriend of his estranged wife and breaking into a business. The stabbing victim is in critical condition at an area hospital, officials said.

Mr. McCuin, of Tyler, about 110 miles east of Dallas, was charged with capital murder. He was being held in the Smith County Jail on a $2 million bond yesterday and did not have an attorney, officials said. He was scheduled to be arraigned today, Mr. Smith said.

Before he called 911, Mr. McCuin told his mother and her boyfriend to look in their garage, authorities said. There the couple saw the remains of Shearer. Mr. McCuin’s mother and her boyfriend fled the home and flagged down a police officer. McCuin dialed authorities after they left.
