A judge rules that a book co-written by Duane Davis, whom prosecutors allege ordered the 1996 killing of rapper Tupac Shakur, is cleared for use during his trial. Multiple outlets report the court’s decision that the book can be introduced as evidence in the case. The reporting describes Shakur’s death as one of the most notorious unsolved murders in the United States, and frames the ruling as part of ongoing pretrial litigation over what materials the prosecution may present. The sources agree that prosecutors contend Davis played an organizing role in Shakur’s murder, while the judge’s order specifically addresses admissibility of the book associated with Davis. The outlets do not provide additional details beyond the fact of the ruling and its relevance to the trial proceedings. The decision means the book will be available to be used as part of the evidentiary record during the trial, subject to any further legal steps or limitations that may arise as the case progresses.
