Affirmed. See I.R. v. State, 385 So.2d 686, 687-88 (Fla. 3d DCA 1980) (“Where the evidence is in conflict, it is within the province of the trier of fact to assess the credibility of witnesses, and upon evaluating the testimony, rely upon the testimony found by it to be worthy of belief and reject such testimony found by it to be untrue.... The testimony of a single witness, even if uncorroborated and contradicted by other State witnesses, is sufficient to sustain a conviction.”).
