James Hamilton pleaded guilty Tuesday in Butler County Common Pleas Court to four charges stemming from the killing of 6-year-old James Hutchinson in February.
On Tuesday, in front of Judge Noah Powers, Hamilton pleaded guilty to kidnapping, gross abuse of a corpse and two counts of child endangering.
Powers told Hamilton he faces up to 19 years in prison.
Police said Gosney was pressured by Hamilton to get rid of her children. Records show she had previously tried to relinquish custody of her children but faced "a number of barriers" when she attempted it.
