The trial court did not err by denying the defendant’s motion to dismiss a charge of conspiracy to sell methamphetamine, given the substantial evidence of an implied understanding among the defendant, Fisher, and Adams to sell methamphetamine to the informants. The informants went to Fisher to buy the drugs. The group then drove to the defendant’s house where Fisher asked the defendant for methamphetamine. The defendant said that he didn’t have any but could get some. The defendant led Fisher and Adams to the trailer where the drugs were purchased.
