Three little boys killed in fire after their grandfather's ex burnt his home a day after she was released from jail

Three boys aged 4, 6 and 10 were killed in a house fire started by their grandfather's ex-girlfriend.

The woman, Marian Evette Williams, 49, of West Davison Street in Bartow, Florida, had threatened to burn the house down a week before but was arrested after she was caught burglarizing the house. She was released from jail a day before the fire.
