Take into account that the front porch is on the SE side of the building, and there was quite a wind last night, SE 15 G 25 (at midnight) Any fire started on that porch would have blown right into the structure.

State Fire Marshall says Arson suspected

However the story says that the fire was first reported as being on the front porch, not that it started there.

It’s been windy up here in Dallas for at least the past 4 or 5 days. Reeeally windy.

On a big renovation job they might well work Saturdays.

But if the fire marshal says it's suspected arson, it's definitely 'incendiary origin'. He's on the scene, and he's no doubt already got his samples in a jar.

So, not a contractor accident, although in renovations that's the way to bet.

I hope they catch 'em quick. What an ugly thing to do.
