The Randolph County Sheriff's Office told local media outlets that Dylon James Kirkpatrick was initially charged with felony child abuse inflicting serious bodily injury and assault with a deadly weapon inflicting serious bodily injury.
The infant was taken to the hospital on Thursday after deputies were called to a home to answer a call about an unresponsive infant.
The child died Saturday from the injuries.
Kirkpatrick, who authorities say is not the child's father, was jailed on a $1 million bond before the murder charge was filed. Online records don't indicate whether he has an attorney.
