(AP) — A Nebraska woman sentenced to up to 22 years in prison for her role in the death of her 2-year-old son has filed an appeal.

Last month, 25-year-old Laura Rinehart, was sentenced after pleading no contest to attempted child abuse in the April 2012 death of Joseph Rinehart Jr.

Authorities say she did nothing to stop the abuse of Joseph by her father, 48-year-old Peter Draper, at the home they all shared in Naponee.

Draper was found guilty of two child abuse charges and is set to be sentenced on Oct. 10.

Rinehart says in her appeal that her sentence was excessive.
