Byron Case spoke to Jackson County Sheriff Detective Gary Kilgore two days after the murder of Anastasia WitbolsFeugen,¹ but consistently avoided any contact with him or any other member of the Sheriff's Department other than by phone afterward, insisting that they had all the information they were going to get from him. From the perspective of Case supporters, this might seem reasonable, as he had "more important things to do" (to use his own phrase)² than to waste his time with police, but when his actions are viewed with the knowledge that he was a suspect in the crime, having been questioned directly by an officer,³ (and that he had admitted that he was aware he was a suspect),⁴,5 his behavior becomes suspicious.

Case would only talk face to face with an investigator one more time, this time only with a promise from the Prosecutor's office not to use any information against him.⁶ After that, Case refused all contact with investigators.

Byron Case cooperated with the murder investigation only to the extent that it suited his purposes.
