PMPT Page 326 - 327: "Hunter called his old friend Bob Kupperman, formerly of the Institute for Strategic and International Studies, who recommended using a psychological linguist, Donald Foster, a professor of dramatic literature at Vassar. Foster studed grammer, syntax, punctuation, style and vocabulary to track down the authors of texts. He had accuratly identified for the FBI source material or parts of Theodore Kaczynski's Unabomber manifesto. He had also identified the writer Joe Klein as the anonymous author of the novel Primary Colors and had identified William Shakespeare as the author of a previously anonymous Elizbethan funeral eulogy."

"Hunter thought that Foster might be helpful in the Ramsey case. Just before the July Fourth weekend, he called Foster, who told the DA that he had once written a letter to Patsy Ramsey and another to her son, John Andrew, while following the case on the Internet. He said he had wanted to lend them some support. Hunter saw no conflict of interest."

"Foster agreed to analyze the ransom note for the DA's office. He would also be sent Janet McReynold's play Hey, Rube,Christmas letters and articles writen by both janet and Bill McReynolds, some of Patsy Ramsey's writings, and transcripts of the Ramsey's January 1 and May 1 press conferences. Not long after hiring Foster, Hunter said that "this case will come down to linguistics."

"For months the Boulder police had been collecting Patsy's handwriting samples: beauty-pageant entry forums, school documents, applications, and business letters. They had recently visited the offices of Hayes Micro Computer in Norcross, Georgia, where Patsy had worked before marrying John. There they found more handwriting samples. This material was relevant for handwriting analysis but was of limited value to Donald Foster. He needed lengthy text and examples of Patsy's prepared and extemporaneous speeches. These would take time to find and even longer to analyze."

If the CBI were to state definitively that Patsy had written the note and Foster were to confirm that finding, Hunter would have something. He worried however, that even with positive findings, his staff might be unable to arrest Patsy. Linguistic analysis had never been used by experts in Colorado courts, so there was a question about whether Foster's findings would be admissible. The professor had never before testified in a criminal trial."
