I'm thinking no because the guy was a hermit. He was a hoarder. The firemen confirmed this when when went into the house. I think the guy was mentally ill. They interbreed, it's common. Mental illness as you can guess runs rampant in their gene pool. They are scared to breed outside their circles. They wanna keep their money intact at all costs. They don't play when it comes to money. Yes, they are rich but they are souless non human creatures. They are demons.
