A Cuyahoga Falls man hospitalized after fire swept his apartment Friday on Prange Drive may have set the blaze .

The Summit County Medical Examiner conducted an autopsy on the body of 29-year old Gregory Hetrick Monday. Hetrick died less than a day later from burns after he was taken to the hospital.

The Medical Examiner's Office said investigators are trying to determine if Hetrick deliberately set the early morning blaze. Investigators say he bought lighter fluid just before the fire.

Three children were rescued from an adjacent apartment after being found alone in the apartment. Their mother, 27-year old Morgan Maffet was eventually charged with three counts of child endangering, after leaving two daughters, five and six years old, and a five year old niece alone in the apartment.
