Kansas City, Mo. ? A 30-year-old man will serve four life sentences without parole for killing a Kansas City-area couple at a Bible store they had operated for 40 years.

Kellen McKinney was sentenced Thursday to two life sentences without parole on two first-degree murder convictions and two life sentences on two armed-criminal action counts. He also got four years for an escape charge.

McKinney, of Kansas City, Kan., was convicted by a Jackson County jury on Feb. 29 for the Oct. 20, 2004, stabbing deaths of John and Mildred Caylor.

A friend saw the couple’s bloody bodies through the window of the Caylors’ Bible and Music Store in Raytown and called police.

Prosecutors said DNA tests linked McKinney to the slayings.
