WABASH, Neb. (AP) — A 37-year-old Cass County man won’t be prosecuted for killing his father.

Cass County Attorney Nathan Cox says David Bouzek acted in self-defense on June 16 when he shot his father. Cox says Gary Bouzek was armed with a hammer when he came at his son.

Cox says that after the elder Bouzek’s release from prison, he was invited to visit his son. They began arguing as David Bouzek was driving to his Murdock home with his dad, and David Bouzek forced his dad to get out. Early on June 16, the younger Bouzek found his father hammering on the outside of his home. The son asked his father to stop. Cox said that when Gary Bouzek came at his son, David Bouzek fired.
