Correct Buzz. Samples of Karr's handwriting in 1996 will be highly sought BY BOTH SIDES. Again, remember that if 1996 handwriting samples of Karr are as compelling as his 1982 year-book, that alone will serve to place him in Boulder and corroborate his confession.
The D.A.'s office removed Karr from California far ahead of the ten days provided for by law . It appears to me that Mary Lacy has a timed evidentiary plan going on in her mind.
Interestingly, on August 23rd, the D.A.'s office said the public interest would be served by keeping secret the affidavit for the arrest warrant for "at least a 15 days".

Further, the D.A.s office said: "We realize that witnesses may have already been exposed to much information about Mr. Karr, some accurate and some not, that has been discovered and published by the media. But we do not think it appropriate at this stage for the information from our investigatory efforts that is in the affidavit to be added to what is being published already."
Given that statement and given the high degree of skepticism expressed about Karr being the murderer, if the alleged incriminating information in the affidavit were to, in fact, have been in the public domain, Mary Lacy would likely voted out of office.
I consider two historical aspects to strongly favor the information in the affidavit being true. First, Mary Lacy has been long been a major part of this high-profile case; she is anything but a Johnny-come-lately to the case. Second, before approving Karr's arrest warrant, the Judge would have almost certainly asked the D.A's team if they had performed a thorough research of case information that exists in the public domain, for nobody in Boulder wants to join the BPD as an object of national ridicule or lose their job as happened to many prior members of the BPD.
