Subsequently, Knight filed the present rule 3.800(a) motion in which he, for a third time, claimed the trial court illegally enhanced the degree of the offense based on his use of a firearm. Without a jury finding that the appellant used a firearm, the enhancement of the degree of the offense of second-degree murder from a second-degree felony to a first-degree felony was improper.
