CHATTANOOGA (WRCB) -- Fire Investigators say the woman charged with setting fire to her home acted alone.

Rodreka Gaines is charged with arson, after her Rawlings Street home suffered substantial damage Tuesday afternoon.

Neighbors told fire investigators Gaines threatened to start the fire because she was mad at her boyfriend.

Fire Officials had named other persons of interest, but now say Gaines acted alone.

Investigators have not said where in the home the fire started.

Gaines goes to court later this month. She's being held on a $15,000 bond.
