Florida fire kills former Falls woman, son

Police treating case as double murder.
Investigators are trying to determine the cause of death.
They don’t know if a 43-year-old mother, a former Niagara Falls resident and her 8-year-old son died before the fire started in their North Port, Florida home or if the fire killed Carolyn and Michael Wisdom.
The State Fire Marshal has determined the blaze was deliberately set in the garage.
The owner of the home is Michael Wisdom, who’d been estranged from wife and had not lived there for at least six months.
He’s been questioned and released.
