If it appears that a defendant or the state is unfairly prejudiced by a joinder of offenses or of defendants in an indictment or information or by such joinder for trial together, the court may order an election or separate trials of counts, grant a severance of defendants, or provide whatever other relief justice requires. A showing that evidence of one offense would not be admissible during a separate trial of a joined offense or a codefendant does not constitute prejudice that warrants relief under this rule. In ruling on a motion by a defendant for severance the court may order the attorney for the state to deliver to the court for inspection in camera any statements or confessions made by the defendants which the state intends to introduce at trial.
