Defendant Carlos Jones appeals his conviction of armed robbery and possession of a firearm by a convicted felon. He challenges the qualifications of a witness permitted to testify as an expert and the sufficiency of the evidence to support his conviction. Since these contentions lack merit, we affirm. 1. On appeal from a criminal conviction, the evidence must be viewed in the light most favorable to the verdict, and the appellant no longer enjoys the presumption of innocence; moreover, an appellate court does not weigh the evidence or determine witness credibility but only determines whether the evidence is sufficient under the standard of Jackson v. Virginia , 443 U. S. 307 99 SC 2781, 61 LEd2d 560 1979. Conflicts in the testimony of the witnesses are a matter of credibility for the jury to resolve. So long as there is some competent evidence, even though contradicted, to support each fact necessary to make out the State’s case, the jury’s verdict will be upheld. Citations and punctuation omitted. Ginn v. State , 293 placeStateGa.App. 757, 758 667 SE2d 712 2008. Viewed in the light most favorable to the jury’s verdict, the trial evidence shows that a single employee was operating a convenience store when someone entered the store and held a gun on her. The perpetrator was a black male weighing about 260 pounds and standing over six feet tall, with his face obscured by a nylon stocking over his head. In spite of the stocking, the store clerk was able to see that the perpetrator had a mustache, bushy eyebrows, and braids in his hair. The robbery lasted about 10 or 15 minutes during which time the perpetrator was speaking as he directed the store clerk to walk over to the cash register, to place the money in a plastic bag, and warned her not to do anything stupid. The store clerk told police that the perpetrator had a deep, scratchy voice.
Three days later, the store clerk was back at work, after taking a couple of days off. The perpetrator returned to the store. On this second occasion, the perpetrator entered the store as a customer and said that he wanted a pack of cigarettes and some gas. The store clerk testified that even though he was tall, of the same weight, and had the same facial hair, she initially recognized the perpetrator by his voice. Later, Jones was identified as the perpetrator in a picture lineup by the store clerk. The State also presented the testimony of an expert polygraph examiner, that Jones showed deception to questions concerning the armed robbery.
