The Jacksonville Sheriff's Office announced the arrest of Charles Deas, 25, after the death of a 3-month-old on June 8.
According to JSO, the investigation ruled that 3-month-old boy died as a result of head trauma from possibly being shaken or some type of battery.
Deas was charged with second degree murder and aggravated manslaughter Friday after an interview on Wednesday, where Deas admitted his actions, JSO said.
According to an arrest report, JSO was called to an apartment on Labelle Street on June 7 in reference to an unresponsive child. The child was taken to Wolfson Children's Hospital, where the boy died.
Deas is the child's father, the JSO report said. On June 7, Deas told JSO that the child was left on a bed and that he heard a thud when he was in another room.
The next day, an autopsy was performed, and the medical examiner ruled the death a homicide. The child suffered head trauma.
Deas was interviewed at JSO headquarters on Oct. 3 and arrested and charged the same day.
