I'm still not sold on the idea that they did it for the money... too much doesn't add up.
I was absolutely obsessed at one time with researching this case. Traded emails with Lutz and DeFeo's wife as well as with Rick Moran and Ric Osuna. There's a LOT to the story.
I was going to suggest that the Lutz's could have believed in the supernatural. That could explain it. They move into a house where a horrible crime took place not too long ago. That would freak almost anybody out.
And let's remember that the Satanic "movement" was in full swing in the early 1970's. The CoS was at full strength until '75 with covens all around the country, including NY. And the movie The Exorcist was still being talked about during that decade with reports of demonic possession in the news.
I'll be open to that.
