They have tons of info.
I would also read this book by James Kolar. He investigated this case, saw every bit of evidence and does not feel like it was an intruder or someone outside of the family.

Last night I bought Foreign Faction and stayed up until 5 am reading it. WOW- thi is definitely the best book I've read dealing with the case and I've read bunches.
Where did I say that it was determined that Patsy wrote the note? I didn't. However, I believe she could not be ruled out.
And what in my post qualifies as a "theory on the internet"? AFAIK those are facts. I'll sum them up and correct me if they are theories and not facts.
Fact: The ransom note was written on a pad belonging to Patsy, using one of her pens.
(comment) The thought of a kidnapper breaking into a house to write a three page ransom note is beyond bizarre. He never worried about being found and took his sweet time to write a really wordy letter.
Fact: Patsy was wearing the same dress as the day before
(comment)kinda strange.
Fact: They didn't wake Burke up to ask if he had heard something which may help find his sister.
Fact: They didn't cooperate with police.
(comment)I'm sure it was under the advise of their lawyers, but when this happened JonBenet was supposedly still alive. I can't Imagine any parents listening to lawyers and not fully cooperating with police so they can find their child as soon as possible!
So, were the points of my post facts, or "theories of the internet"?
In the book above, a handwriting expert said the note matched Patsy's handwriting -24 out of 26 letters of the alphabet. ANother expert said sometimes people's writing can change but what doesn't change is the way they use and phrase their vocabulary. He compared notes and letters Patsy had written over the years to the ransom notes and determined soem were identical and that she had written the ransom letter.
Oh and the 911 call- apparently the author was able to get it cleaned up and Patsy's panicky voice disappeared when she thought she had hung up the phone.
After John found Jon Benet's body and Fleet White ran upstairs screaming for an ambulance and that John is coming, the women sitting with Patsy in another room run to see about Jon Benet. Patsy just sits in the chair in the other room and doesn't move to see about her daughter. I think most of us would run like bats out of hell to check on our child especially if we believed our daughter had been kidnapped and then she was found.
