Another Weed resident is suing the owner of the lumber mill linked to last month’s deadly wildfire, blasting the company for storing hot ash in a warehouse that burned to the ground. Robert Davies, 61, whose home was destroyed when the Mill Fire spread through Weed, sued Roseburg Forest Products Co., claiming the company failed to install a functioning sprinkler system that could have prevented the disaster. Two people were killed when fire leapt from Roseburg’s property to the nearby Lincoln Heights neighborhood the afternoon of Sept. 2. Davies’ lawsuit, filed in San Francisco Superior Court, is at least the third lawsuit filed against Roseburg. Investigators from Cal Fire are focusing on an old warehouse, known as Shed 17, where the fire appears to have started.
