Have they found the arsonist(s) yet?

Not this one. The Lahaina fire started when a power line fell onto a dry grassy area. There were multiple witnesses of the event, to include a cell phone video.

But the power company said that the power was cut off hours before the storm/fires.

The first fire...
They de energized the lines, so the second, deadly fire was not caused by the power lines...
