Why doesn't anyone think it could've been John.

Patsy definitely wrote the ransom letters. So she was involved and probably did all of the acts without his knowledge.

Folks, for those saying PDI - for bedwetting

That only explains the blow to the head - and then the garrote and strangulation to cover it up,
IT DOES NOT EXPLAIN away the genital trauma from paintbrush.

I can't believe she would do that as part of staging. Just no. This in no way can be just PDI on that basis?

Perhaps John was molesting JBR. John could have done the genital trauma with the paintbrush to JBR's dead body to explain away the genital trauma so that John was not revealed to be a child molester.

IDI was not investigated enough ?

Very unlikely I agree, but not impossible that someone say who used to work for them as a gardener or cleaner who knew the layout of the house and where they kept things and hated them for some reason - came in through the window and originally intended ransoming - but then perhaps JB woke up and struggled and hence the killing was a spontaneous reaction with motive being some personal jealousy against JR+PR

It isnt wholly impossible ? It has achieved not just doing away their daughter but tarring their names forever?
