Kansas City, Mo. ? A federal judge followed a jury’s recommendation and imposed the death sentence Friday against a northeast Kansas man convicted of killing an Independence teenager and dismembering her body with a chain saw.

Jurors in November convicted Wesley Ira Purkey, 51, of Lansing, Kan., of kidnapping, raping and fatally stabbing 16-year-old Jennifer Long on Jan. 22, 1998. Afterward, he burned the teen’s dismembered body in his fireplace.

Before the sentence was imposed Friday, Purkey apologized to Long’s father, William Long.

“It’s cost me everything. It cost me my child,” Long told KMBC-TV after the sentence was imposed. “There will be no closure until he does take that last breath, because every day I think about him.”

The girl’s disappearance was a mystery until December 1998, when Purkey, hoping his cooperation would bring him a lighter sentence in the death of an elderly woman, admitted to law enforcement officers that he had kidnapped and killed Long. Purkey was sentenced in April 2000 to life in prison for the October 1998 beating death of 80-year-old Ruth Bales at her home in Kansas City, Kan.
