Idaho murders: New book on Kohberger reveals previously unseen evidence, claims sheath could be inadmissible

A new book on the Idaho student murders case reveals previously unseen evidence suggesting the defense could have challenged the admissibility of a critical piece of evidence—a Ka-Bar knife sheath—due to chain of custody concerns. The book, 'Broken Plea,' highlights flaws in the evidence handling process, including duplicate dates and signatures on the evidence bag, which could have undermined the prosecution's case if the trial had proceeded.
