A Kansas woman whose conviction for involuntary manslaughter was overturned pleaded no contest to a lesser charge and was sentenced to time served.

Thirty-one-year-old Monica F. Rivera of Leavenworth spent 28 months in prison while appealing her conviction for involuntary manslaughter and endangering a child in the 2009 death of her 4-year-old son.

The boy died of blunt force trauma while he was being cared for by Rivera’s boyfriend, Jason L. Jones.

Rivera pleaded no contest Friday to aggravated endangering a child and was sentenced to time served.

The Kansas Court of Appeals ordered a new trial after finding errors in jury instructions during Rivera’s 2010 trial.

Jones is serving more than 38 years in prison for second-degree murder in the boy’s death.
