TOPEKA, Kan. (AP) — A Jackson County teenager has pleaded guilty to severely beating an infant.

WIBW-TV reports 18-year-old Koylen McKinney pleaded guilty Thursday to aggravated battery, abuse of a child and aggravated endangerment of a child.

McKinney was arrested in April after medics found the 7-month-old boy unresponsive at a Holton apartment complex. The infant was in a medically induced coma following the attack. He was later released from the hospital.

McKinney was 17 years old at the time of the incident but was tried as an adult. His relationship with the boy is unclear. He faces more than 14 years in prison when he is sentenced.
