Family and supporters of Byron Case have argued that Kelly Moffett told multiple versions of what happened on the night of October 22, 1997 to police, that she changed her story back and forth as it suited her. They believe that this shows strong evidence that she fabricated her entire story, and that it supports Case's claim that she was a "pathological liar".

In her three statements to police between 1997 and 1998, Kelly Moffett's story was essentially identical to the one Byron Case told, based on what she and Case had previously agreed to say.¹ In a statement made September 21, 2000, Moffett repudiated her earlier statement and stated that she had witnessed the murder of Anastasia WitbolsFeugen by Byron Case.

In between that time, Moffett had finally admitted to her mother in March 2000 that she had witnessed Anastasia's murder, but did not directly name Anastasia's killer herself. When her mother asked her the question "Was it Justin?", Moffett let her believe that; she did not specifically name Justin Bruton as the killer, but did let her mother believe that misconception.² She finally admitted in June 2000 in a long conversation with her father that Byron Case had committed the murder.³ When she admitted to her rehab counselor in September 2000 that she had witnessed the murder and was informed that the counselor would immediately call the police, she panicked and reverted to accusing Justin Bruton of the murder; when her mother arrived at the rehab and challenged her, she admitted that it was Byron Case.4,5

Kelly Moffett did not want to incriminate Byron Case to the police. Even after admitting to her mother that she had witnessed Anastasia's murder, avoided naming Case for three months. When she admitted to her father that the killer was Byron Case (a full three months before Case left Kansas City for St. Louis, eliminating the "motive" he claims she had to accuse him), she did not go to the police at that time. When she finally admitted Case's culpability to her rehab counselor, she did so under the impression that it would be kept confidential; when told that it would not, she panicked, and tried to cover by accusing a long-dead friend.

Kelly Moffett told two versions of Anastasia's final night to police, one of them the lie Byron Case asked her to tell, the second one repudiating that lie. The fact that she might first allow a friend who was already dead and beyond the law to be incriminated is hardly surprising. What Case supporters want to call dishonesty was nothing more than Moffett's initial effort to admit having witnessed the crime while still trying to protect Case's anonymity. In the end, she could not protect him, and in the end, he did not deserve that protection.
