GREAT BEND, Kansas – A Barton County man was sentenced Thursday to life in prison without the possibility of parole for at least 25 years.

Jeffrey Wade Chapman, 33, Pawnee Rock, was found guilty in February by a Barton County jury of first-degree premeditated murder.

District Court Judge Ron Svaty sentenced Chapman to life in the Kansas Department of Corrections without eligibility for parole for 25 years.

Prosecutors argued that Chapman killed Galyardt because of the way he was treating a mutual friend. Chapman claimed he shot Galyardt in self-defense.

Chapman was charged with the crime in connection with the November 2011 death of Damon L. Galyardt of Great Bend.

The case was investigated by Great Bend Police Department, Barton County Sheriff’s Office and Kansas Bureau of Investigation.
