I photograph homes. It's normal, people die in homes. I've photographed a few homes where the reason for sale was a recent suicide in the home. I photographed a new home that the builder killed himself in the garage just before the project was complete.
The weirdest one was mostly very creepy and suspicious. I photographed a billionaire's compound where the guy had and absurd fascination with flesh. There were well over 50 heads mounted on walls from water buffalo to elephant. 5-10 large cats, stuffed. Chandeliers made from the feathers of rare birds. Stools made from elephant feet/legs, they were hairy, ugh. Paintings and abstract photos of oily skin, "veiny" muscles of humans and animals etc etc. I looked for his kill room, but I never found it. In general I find billionaires don't behave like normal people, but this one was particularly weird.Source
When we were looking to buy a house we looked at one in which the father of the family committed suicide in. You could tell which room it was because it had clearly recently been sheet rocked and painted. It didn't really bother us though and we didn't get any creepy feelings. We chose not to put an offer in because the rest of the house needed a lot of work.Source
