A 30-year-old Kansas woman has pleaded guilty to charges in the death of her 7-year-old stepson whose remains were found among the family's pigs.

Heather Jones pleaded guilty Thursday in Wyandotte County court to first-degree murder in the death of the child, whom authorities referred to as A.J. Chief Deputy District Attorney Sheryl Lidtke says the first-degree murder charge carries a sentence of life without a chance for parole for at least 25 years.

Jones was charged along with her husband, Michael Jones, in the death of his son after authorities found the child's remains when they were called to investigate a domestic disturbance at the family's rented property last November.

Lidtke says the cause of death was "chronic abuse." Heather Jones' sentencing is Nov. 14.

Michael Jones is scheduled for a jury trial in February 2017.
