An Ohio mother accused of abandoning her three children in a park and killing one as he desperately tried to get back into their car has pleaded guilty. Brittany Gosney, 29, of Middletown, pleaded guilty to murder and two felony counts of child endangerment Monday as part of a plea deal in the February death of her 6-year-old son, James Hutchinson, whose body is still missing, the Cincinnati Enquirer reported. She had faced a total of 16 charges, including kidnapping, after authorities said she admitted abandoning her son and his two siblings, ages 7 and 9, at a Preble County park on Feb. 26, WXIX reported. Authorities said 6-year-old James grabbed for the car’s door handle but fell as Gosney tried to speed away. He fatally struck his head while being dragged, police said. Gosney left the park, but returned for her three children about 40 minutes later and found James dead and her other two kids unharmed, according to authorities. Gosney and her boyfriend, James Hamilton, 43, put her son’s body in a spare bedroom for two days before dumping it in the Ohio River in Lawrenceburg, Indiana, court records show.
