Fire Update: house heater

Quick update, the Forensic Fire Investigator has traced that the fire was caused by the house heater. Also in further research of smoke detectors I guess there’s a plethora out there on the market to choose from and there are other alternatives to the smoke detectors like ones that detect heat/temperature (though not sure how that will fare in So. Cali.). Choice will depend on your perceived need or budget. I have nothing conclusive at this point and will further research and share as I get more information. Thanks for your time and your prayers!
