COUNCIL BLUFFS, Iowa (AP) — A man accused of beating to death his grandmother in Council Bluffs has been sentenced to 50 years in prison. Court records say 30-year-old Jacob Heyer pleaded guilty Monday to second-degree murder. Prosecutors lowered the charge from first-degree murder in exchange for Heyer’s plea. Heyer was arrested in August 2018 for the assault of 71-year-old Karen Fort. She died within a month, and his original charges were raised. Heyer’s grandfather told officers that Heyer had said Fort tried to kill him.
