Never thought about it being fatal, though!
I hate "estate" sales like that, I have been to many and the best thing to do with that sale is put a dumpster out front and empty the entire house into dumpster.
Our next-door neighbors had that problem. They lost their home and the new owner filled two commercial dumpsters, and made special arrangements with local trash pickup to make multiple stops to get the rest. It took him and a cleaning crew a week just to empty out the house.
When our *poor* welfare neighbors moved out (abandoned the place) the landlord hired another neighbor to clean out the place. They used snow shovels and just stuffed it into MANY garbage bags. UNBELIEVABLE. Along with the stench.
