That has been the hardest thing for me to process.We know for sure he was alive when the housekeeper went to change the bulb as she heard him snoring.The fact that he passed while people were in the house is really really hard to accept.
I don't think we know this for sure. I remember those reports from pretty early, but also remember later reports saying he was already dead (omg, this is STILL hard to type
) when the housekeeper came into the apartment and that she could not have heard him snore.
I don't know which version is true, and I doubt we'll ever know it for sure.
Remember all those stories and rumours from the first hours/days, like for example there were allegedly pills scattered around him, and other details which turned out wrong.
