Byron Case's family and supporters 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 his claim that she was a "pathological liar".

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

In between that time, she had finally admitted to her mother in March 2000 that she had witnessed Anastasia's murder, but did not directly name Case herself. When her mother asked her the question "Was it Justin?", she let her mother believe that; she did not specifically name Justin Bruton as the killer, but did let her mother believe that misconception.² In a long conversation with her father in June 2000, She finally admitted that Byron Case had committed the murder.³ When she admitted to her rehab counselor, Maggie, in September 2000 that she had witnessed the murder, Maggie told her that it was a legal duty of hers to inform the police of a crime. Kelly had assumed her admission to the counselor would be confidential, and panicked when informed differently. She reverted to accusing Justin Bruton of the murder; when her mother arrived at the rehab and challenged her, she admitted that it was her ex-boyfriend.4,5

She feared incriminating Byron Case to the police, as he had already convinced her that she would face the same penalties as he. Even after admitting to her mother that she had witnessed Anastasia's murder, she avoided directly naming the killer for three months. When she admitted to her father who the killer truly was (a full three months before he 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 his 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 he had coerced her into telling, and 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's supporters want to call dishonesty was nothing more than her initial effort to admit having witnessed the crime while still trying to protect his anonymity. In the end, she could not protect him, and in the end, he did not deserve that protection.
