Byron Case asserted during his trial that Kelly Moffett was just a "traditional psychotic ex-girlfriend",¹ that she was manipulative and vindictive, and that her entire motive for accusing him of murder was to gain revenge for breaking up with her. It has practically become the mantra of many of Case's supporters to describe Kelly as an "embittered ex-girlfriend with a history of drug use and mental health issues," with little if any real thought or investigation into that claim.

Let us first examine the claims of Case and his supporters. First, the claim that Kelly was bitter about having broken up with Case has its origin in a story fabricated by Case himself,² never having been brought up in testimony during the trial, never having been brought up in any of his three appeals.

Did Case even break up with Moffett himself, or was it the other way around? Kelly Moffett remembered that it was she who broke up with Case,³ and Byron Case confirmed it in his own testimony.⁴ They broke up in December 1998 or January 1999, some 21 months before she actually accused him of murder. Kelly had already admitted to her father in June 2000 that she had witnessed Case commit the murder⁵ three months before Case left for St. Louis in September 2000.⁶

With the breakup more than one year after Anastasia's murder and nearly two years before Case's departure, it is not a reasonable assumption to consider Kelly Moffett to have been "embittered" about the breakup, and it does not provide any such motive for her to accuse Case of murder. For the record, Moffett had already first named Case as Anastasia's killer three months before she learned that he was leaving Kansas City, and they had broken up about a year and a half before she made that first accusation. As Byron Case once wrote so rather rudely to Anastasia's family,⁷ do the math.

Kelly Moffett tesified that her major drug problems were a result of the trauma of witnessing Anastasia's murder, that she had thought she would be able to talk about it confidentially,⁽⁸⁾ and only came forward to police when there was no other choice.

As far as Kelly's "history of drug use and mental health issues", she admitted using recreational drugs before having witnessed the murder, but that her use became chronic only after October 22, 1997.⁹ Byron Case attempted to gain access to her mental health records¹⁰ in an effort to "prove" that she was a "chronic, pathological liar",¹¹ but the judge in the case refused that access after having viewed the records himself in camera.¹²

Case's supporters also have repeatedly insisted that they have provided all the documentation about the investigation and trial of this case that is necessary. This is untrue. They have approximately half of the more than 2,000 pages of documents created between October 23, 1997 and May 2, 2002. They also have failed completely to provide any documentation to prove their main points about Kelly Moffett's alleged heavy drug use before the murder, using only Byron Case's uncorroborated claims as their sole source.

This claim was kept on the killer's website for a long time:

"Kelly used drugs before Byron ever met her, during their relationship, after Anastasia was shot, 
and may still to this day. She did not start using drugs as a coping mechanism for supposedly 
witnessing Stasia's murder. She was a wild, wild girl."

And this (from someone who was acquainted with Moffett for only a matter of a few weeks):

"It was also usual behavior for Kelly to lie and make up stories."

The fact is that these accusations were made while providing no source for any of the speculations about a woman that the writer had met only a handful of times, and about whom knew very little more than the misinformation that Byron Case had provided, and that this seems nothing more than an excellent example of Kettle and Pot name-calling.

A pattern also became apparent during testimony that all of Case's family's and friends' perception of Kelly had been filtered through Case himself,¹³,14 as all perceptions of Moffett were second-hand, never confirmed by Moffett herself, and heavily influenced by what they were told by Case when Moffett wasn't in the room.

There have also been a few accusations made by Case supporters that Kelly Moffett turned on Byron Case to collect the reward offered in the case. This has been dealt with in another section.¹⁵

The claims made by Case supporters about Kelly Moffett since his conviction have all been made without any documentation, and again all parrot Case's unsubstantiated claims against her, apparently showing no interest in providing proof.

In his findings at the sentencing of Byron Case, Judge Charles Atwell said this of the efforts to impeach Kelly Moffett's motives:

"I also believe from the testimony that was presented that there really was no motive that I think 
is believable that would give Kelly Moffett a reason to lie and to incriminate this Defendant.

"The evidence was that their relationship had long since severed well before she came forward; that 
the contact with each other was very insubstantial at the time she came forward; and I found no 
evidence that would suggest a real motive for her going from claiming innocence to putting herself 
in a trick bag for conspiracy to commit murder, and somehow putting in prison an innocent person 
who she had once had a relationship with.
                 
"I just didn't find a motive that seemed reasonable to me. I suspect the jury may well have thought 
that also."16

Kelly Moffett came forward to accuse and testify against Byron Case, not because she sought some sick revenge, but because she could no longer deal with the strain of having witnessed the murder of a friend and having to keep her knowledge secret while watching the killer himself walk away from what he had done without conscience or regret. She came forward to see justice done.
