A Sigourney man is facing voluntary manslaughter charges after allegedly killing his father. The Iowa Department of Public Safety says 32 year old Kenneth Lundy is being held in the Keokuk County Jail, pending an initial appearance before a district Judge. They say Lundy got into a heated argument with his father, 61 year old Kenneth Lundy early Thursday morning. The argument escalated and both men retrieved firearms. Authorities say Kenneth Lundy shot his father, who was pronounced dead at the scene. The State Medical Examiners Office plans to perform an autopsy later this week. Lundy is considered innocent unless proven guilty.
