The trial court did not abuse its discretion by denying the defendant’s motion to continue to test certain hair and fiber lifts from an item of clothing. The defendant had six months to prepare for trial and obtain independent testing, but waited until the day of trial to file his motion, in violation G.S. 15A-952(c). This failure to file the motion to continue within the required time period constituted a waiver of the motion. Also, because the item had already been DNA tested by the State, the lifts were not the only physical evidence obtained.
