Ryan Lawrence, 25, of New York, pleaded guilty to first-degree murder for killing his 21-month old daughter in February, WRGB-TV reported.
Maddox, who suffered from eye cancer and survived, said he hit his daughter because of all the attention she was getting due to her illness.
Lawrence is expected to get a 25-year-to-life sentence as part of his plea in Onondaga County Court. He admitted to beating his daughter, Maddox, to death with a baseball bat, burning her body for several hours in a fire pit, then dumping her remains in a nearby creek, Syracuse.com reported.
Maddox’ family agreed to the plea deal, seeing that Lawrence will go in front a parole board after serving his 25 years.
