(ELIZABETHTOWN, Ky.) -- The mother of a 3-year-old infant who was beaten to death has pleaded guilty in Hardin County to abusing the child.
Her former boyfriend is charged with killing the boy, Ryan Arnold, in August of 2004.
Andrea Arnold had also faced a murder charge but reached a deal with prosecutors yesterday. The deal calls for her to serve 10 years in prison.
Police say her ex-boyfriend -- 27-year-old Russell Sullivan -- assaulted the child, leaving him with a massive closed-head injury. He later died at a hospital.
Sullivan is charged with murder and first-degree criminal abuse.
