Byron Case's audiotaped tacit admission ¹ was one of two keys to his conviction,² Kelly Moffett's eyewitness testimony being the other. Both were necessary for the State's case to succeed.

Case did not directly admit to anything during the course of his conversation with Moffett, but he appeared very suspicious of her motive for calling in the first place, and is known to be highly clever, so his guardedness was to be expected. However, after more than three minutes of conversation in which the main topic was Anastasia's murder and the fact that police wanted to talk to Moffett again (during which time Case made no attempt to redirect conversation), Case was directly asked why he killed Anastasia, he suddenly went silent, and then changed the subject by telling her "We shouldn't talk about this".³

Many Case supporters have made the mistake of believing that Case was convicted solely on the testimony of Kelly Moffett,⁴ but it was her testimony, coupled with Case's own words, along with several lesser elements, that led to his conviction.
