Below are quotes from others who investigated and/or analyzed the RN and their conclusions re PR as the author of the note:
"Colorado Bureau of Investigation handwriting expert Chet Ubowski expressed concerns that 'the handwriting samples obtained from Patsy Ramsey do not suggest the full range of her handwriting.'"

"Carol McKinley stated in the Fox News story that Ramseys sued Fox over: 'Many forensic document examiners have given their opinions as to who wrote the note. But the only one to testify before a grand jury in the case was Chet Ubowski, forensic document examiner for the Colorado Bureau of Investigation. Out of 100 people he analyzed for the Boulder Police Department, he found ONLY ONE person whom he thought may have authored the document, Patsy Ramsey. Investigative sources tell Fox News that the disguised letters and bleeding ink from the felt tipped pen used to write the note kept him from 100 percent ID of Mrs. Ramsey.'"

Leonard Speckin
•Speckin Findings.
1.Unable to Eliminate. "Leonard Speckin, a private forensic document examiner, concluded that differences between the writing of Mrs. Ramsey's handwriting and the author of the Ransom Note prevented him from identifying Mrs. Ramsey as the author of the Ransom Note, but he was unable to eliminate her. (SMF P 198; PSMF P 198.)" (Carnes 2003:26, note 14). Speckin's report stated: "When I compare the handwriting habits of Patsy Ramsey with those in the questioned ransom note, there exists agreement to the extent that some of her individual letter formations and letter combinations do appear in the ransom note." (Epstein Deposition (p. 138:9-14) "When this agreement is weighed against the number, type and consistency of the differences present, I am unable to identify Patsy Ramsey as the author of the questioned ransom note with any degree of certainty. I am, however, unable to eliminate her as the author." (Epstein Deposition (p. 138:25 through p. 139:1-6).
2.Infinitesimal Chance of Intruder Match to Patsy. However, Speckin reportedly was ready to testify that "there was only an infinitesimal chance that some random intruder would have handwriting characteristics so remarkably similar to those of a parent sleeping upstairs." (Thomas 2000
