Tragic.   I hope they all make it.
About 10 years ago, my neighbor two houses down burned down his entire house.  He was using a propane grill in an attached screen porch.  The grill flared up and he couldn't react fast enough to remedy the situation.   
I was pulling into my driveway just as their house was in full blaze.  For the next half hour or so I was up on my own roof putting out flaming sheets of debris that wafted up and landed on my house.   
Fortunately nobody was injured or killed.
