OK!!! Why didn't his brother or sister particiapte!?

Assuming this was true or even half true (something I am NOT convinced of at all) at that young age their current memories are likely to be hazy at best. I'm not sure how reliable any information they have will be.

Cause the guy needs more money and the siblings want nothing to do with the fathers lie. The guys an obvious nutcase probably because of domestic abuse

I honestly can't figure out why Chris didn't participate. Maybe him and Danny don't get alone and he didn't want to be a part of Danny's project. But Chris has given many recent interviews, he even did a Coast to Coast session a few years back - and he basically said in a nutshell that yes, George was a big liar and a lot of the stuff in the book was fabricated but the house was indeed haunted and things happened to them.

After doing a ton of research on this case, the Lutz's experienced some paranormal activity. They contacted Butch Defeo's attorney because they thought that maybe Butch had experienced this stuff too and from there, it just spun out of control. These poor children got caught up in everything and unfortunately, became pretty *beep* up mentally because of it.
