While the exact means of his death was in a fire on someone else's property, it was during this time the billionaire was indeed living in a shit-covered hovel:
> There was feces on the ground. Plants in his toilets. Broken glass, broken plates all over the ground. Rotten food under the bed. Rotten food on the walls... it was disgusting.
No. He died in a house fire at someone's house that he was visiting.
