Cecil, it's Lusk. I just got off the phone with Cathy. She is the person at PB who answers the phone and does a bunch of the work to keep things happening. I asked her to call me if there was anything we could do to help. She has all of my numbers and will convey to Lusk our concern and wishes to help.
They believe it was an electrical fire that started in the attic. Bob was not home but his wife Debbie, a daughter and granddaughter were there. They got out OK. They had purchased an existing home and had done a lot of remodeling. That may or may not have been a contributing factor but even speculation of the cause is premature.
