One thing sticks out about the apartment building fire that engulfed the construction site of controversial developer Geoff Palmer’s 1.3 million-square-foot wooden Da Vinci complex early yesterday morning: the immediate announcement of the possibility of arson. It is extremely unusual for Los Angeles fire department officials to raise the possibility of arson on the same day, indeed, the same morning, of a major conflagration. It is likely that there will be at least two such investigations into the matter, one by the city and one by the federal ATF, and possibly a third by Palmer’s insurer. At this point, considering the extent and intensity of the fire, it is being termed suspicious. Officials have already said they want to look at Palmer Associates’ financial records—which have been obscure, since the firm is privately held.
