Bill Beadle said in the Q&A that Douglas participated in the earlier 1981 study "at the University of Kansas" and that's where his first profile was made. Is this true? I assume he meant Eckert's work done for Wichita State University's "Ripper Project". I was under the impression that Douglas didn't get involved in the project until Eckert suggested him to the producers at Fox for the television program. I looked through old Casebook threads about the WSU stuff and saw that I was trying to track it all down 10 years ago. I received material from Stewart Evans but that was about as far as I got.
I do not believe Douglas was involved that early but I stand to be corrected.
Douglas states in his 1995 book Mind Hunter that "Back in 1988 I was asked to analyze the Ripper murders for a nationally broadcast television program." He says very much the same thing in his 2000 book The Cases That Still Haunt Us. It seems unlikely that he provided Eckert with a profile in 1981, although he does write that he has had a long standing interest in the Ripper case.
My confusion, and possibly Bill Beadle's also, stems from how Eckert describes Douglas' involvement in the 1981 Wichita State University Ripper Project in a paper published about it in 1989 which, Eckert mentions at the end, culminated in the television program.
