Ok. Your post was too cryptic. I thought you were talking about the hand writing expert who said Patsy Ramsey (now deceased) was the author of the ransom note.
Yes, it deserves an eyeroll for sarcasm. Should have added one.
Obviously, the first question asks how the person (Meyer) would've/could've come about the knowledge to include certain information written in the note. Failing to have an answer for that, though, may be why the "news story" must point out that the amount noted wasn't exactly the same as J. Ramsey's bonus. It was slightly more. Alrighty.
Pretty sure the CBI (Colorado) has said it appears to be the work of Mrs. Ramsey. Yes. It remains consistent with everything else about it, too, which says quite a lot.
These stories, with headlines like "Case Closed?" are just so irresponsibly done. But to make a case about false accusations by making false accusations, lol, is even worse than that.
