(AP) – Videos showing downed power lines apparently sparking some of the early blazes in the Maui wildfires have become key evidence in the search for a cause. Hawaiian Electric Co. faces criticism for not shutting off the power amid high wind warnings. A class-action lawsuit has already been filed seeking to hold the company responsible for the deaths of at least 99 people. The lawsuit cites the utility’s own documents from last year showing it was aware that preemptive power shutoffs such as those used in California were an effective strategy to prevent wildfires but never adopted them.
