Are there many pieces missing if we choose to build a theory around the LHP group?
She was distraught over her sister demanding money before Christmas.
She knew the bonus amount John Ramsey received.
She had a key,
had arrangements in place for that key to be used on the 26th or 27th, to pick up a check on the kitchen counter.( this always seemed important to me, IF I were picking up a check I needed so desperately , would I wait until Friday or have my husband go grab it for me on the first banking day???)
Table conversation at Christmas dinner most likely included "check chat", and could have included something to this effect, " I borrowed money from that fat cat, how humiliating, they could have given me that money out of their petty cash, he afterall earned a 118,000 dollar bonus this year".
Conversations could have flown with... "princess daughter" has more spent on her pagaent dresses than Merv earns, ..wasn't good enough to attend party...after thought Patsy gave Arianna something suitable to wear...
In fact they could have built quite a disturbing case, a hate case against the Ramseys during their Christmas dinner of tacos.
I believe Jonbenet knew her killer, I believe the garrote was intended as a "dog leash" and an accident happened, I believe,as well, whoever killed her may not have gone in with that intention. The scene could have been staged after the fact and covered by a caring wife . IMO it looks like a "couple", a son/mother, wife/husband, brother/sister, with one called in to "clean" up for the one who was the perp. The LHP's look good as suspects, however, we don't know if there were others in the neighborhood that could look just as good. No one bothered to check, at minimum those who moved away should have been investigated.
