In Jones v. State, 207 Ga. App. 46, 47 (1) (427 S.E.2d 40) (1993) where the defendant was charged with possession of cocaine with intent to distribute, we held that urinalysis results showing the presence of cocaine in the defendant's system were "admissible as part of the res gestae and as circumstantial evidence that he was involved in drug activity." In so holding, the Court noted that the state is entitled to present evidence of the entire res gestae of the crime. Even though a defendant is not charged with every crime committed during a criminal transaction, every aspect of it relevant to the crime charged may be presented at trial. This is true even if the defendant's character is incidentally placed in issue.
