Quinton Darryl Huett is accused of beating his girlfriend's 21 month old son, Jordan Evans, to death in 2012.
The Harrison Daily Times says Huett agreed to a plea deal Friday for a lesser charge. He will be sentenced to 40 years in prison.
The child was taken to the North Arkansas Regional Medical Center (NARMC) in March, 2012, where she was given CPR.
Emergency personnel, according to court documents, noticed bruises on the child.
The child was placed on a ventilator and was later airlifted to Little Rock Children's Hospital. She died there Wednesday just after 3 p.m.
The alleged abuse happened at the mother's home at 620 S. Sycamore Street in Harrison.
According to court documents, Huett was angry with the child for distracting him from a video game. He allegedly "squeezed the child until the child stopped breathing, and then threw the child head-first into a wooden crib, causing a skull fracture, bleeding of the brain, live and spleen lacerations, retinal hemorrhaging, and swelling and multiple bruises to the body."
Huett allegedly told doctors at NARMC earlier in the week that the child "has been sick with pneumonia, but was not acting normal." Court documents allege he told hospital officials he'd put the child down for a nap only to realize within 10 minutes that she wasn't breathing.
