The finding by city investigators was substantiated by an investigation by the state fire marshal, Cunningham said. He was unaware of what finding that the two agencies had used to base their common finding, which reversed the initial determination that the fire was accidental and not suspicious.

Investigators have not identified a motive or suspect, Cunningham said. The department will hold a press conference at its headquarters Wednesday morning, he said.

Okay, assuming the arsonist is apprehended, what would be the appropriate penalty for setting fire to a house full of children?
