Johnson’s trial was delayed 680 days.  The plurality opinion (by Pierce, joined by Carlson and Randolph, with Lamar joining in the result only) concedes Johnson proved 3 of 4 factors for a speedy trial claim in his favor– the delay was well past the 8 month period that was presumptively prejudicial,  he made timely demands for a trial, and the state proved little or nothing to show the reason for delay.  That left only the fourth factor, whether he was prejudiced.
