The extent of the tragedy is still unknown. The fire, sped by winds of 60-90 mph, moved so fast that people were caught in their homes or in the woods. Bodies are being discovered as the recovery begins. A gentleman interviewed on the national news when the fires began who was trying to locate his wife and 12-year-old daughter discovered yesterday both had died when the fire engulfed their home.

The Diocese took a collection at every parish this weekend and will repeat it next weekend to aid the survivors.
