A jury in Kansas has convicted the former head of the Columbia City Utility Department of murdering his estranged wife, their two daughters, and his wife’s grandmother.  The lawyer for James Kraig Kahler had argued Kahler’s mental health had declined after his wife began a lesbian affair and filed for divorce. Witnesses say Kahler’s obsession with saving his marriage led to his firing as Columbia’s City Utilities Director.

Jurors will next decide what punishment to recommend.
