A Delaware mother is going to prison after pleading guilty to murder-by-neglect of her infant son

Casey Layton was sentenced to 15 years in prison for her role in the 2015 death of her son, Aiden Hundley.

She pled guilty along with the child's father, Doyle Hundley. Hundley has not been sentenced, to date.

The couple called police in May 2015 saying their 3-month-old son was unresponsive.

Doctors found the baby had multiple injuries and was severely malnourished.

Aiden lived on life support five months before dying in September of 2015.

An autopsy found the child had died from blunt-force trauma to the head.
