At the time of defendant’s trial, the governing law authorized the use of hypothetical questions such as the questions posed to the State’s experts in this case. And in light of the distinctions between Melendez and the present case, there was no error in the trial court’s admission of defendant’s notice of motion for a writ of replevin and certification.
