Authorities say the fire was reported about 3:30 a.m. at a home that Gibble and Jenkins rented. When firefighters arrived, they found Gibble outside the home, trying to revive his mother.
Jenkins was taken to a Gastonia hospital, where she died of her injuries.
Gibble was arrested Monday and is being held without bond. He has a lengthy record of arrests, according to North Carolina legal records, and served about six years in prison.
Over the years, he has been charged with DWI, drug offenses and assault.
Police have not said what the motive might have been for the fire.
