(AP) — A northwest Missouri woman was sentenced to eight years in prison for beating her husband to death with a hammer.

Catherine Ashworth did not speak during sentencing Thursday in Jackson County Circuit Court. He pleaded guilty in November to manslaughter for killing her husband, 64-year-old Ronnie Ashworth Sr., in August of 2010.

She said that she hit her husband several times in the head with a hammer after they argued about infidelity.

Ashworth was charged with second-degree murder before accepting a plea deal.
