v.
The STATE.
No. S01A1185.
Supreme Court of Georgia.

*804 Charles E. Day, Monroe, for appellant.

CARLEY, Justice.
A jury found Mastro Almond guilty of malice murder and the sale of cocaine. He appeals from the judgments of conviction and sentences entered by the trial court on the jury's guilty verdicts.[1]
1. At trial, eyewitnesses testified that Almond sold cocaine to the victim and, after a dispute regarding payment arose, fatally shot him. The State produced additional evidence that appellant was the shooter, including proof that his gun was the murder weapon and that he admitted to others that he killed the victim. He contends that the prosecution witnesses were biased against him, but they were subject to a thorough and sifting cross-examination by the defense. Thus, the credibility of their testimony was for the jury. When construed most strongly in favor of the verdict, the evidence was sufficient to authorize a rational trier of fact to find proof of his commission of the murder and the sale of drugs beyond a reasonable doubt. Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979).
2. After qualifying the investigating officer as an expert in crime scene reconstruction, the prosecuting attorney asked whether he had "formed an opinion as to *805 what happened?" The trial court permitted the witness to answer, over a defense objection that the question was so broad as to elicit an opinion on the ultimate issue in the case and to invade the province of the jury. Almond enumerates this evidentiary ruling as error.
The State did not seek the officer's opinion as to appellant's guilt. In a criminal case, an expert is permitted to state an "opinion that, based on his experience and training in the field of criminal investigation and crime scene reconstruction, the physical evidence was consistent with a hypothetical sequence of events surrounding the shooting." (Emphasis omitted.) Coleman v. State, 257 Ga. 313, 314(1), 357 S.E.2d 566 (1987). Almond raised an initial objection only to the form of the question, and did not subsequently assert that the officer's actual testimony exceeded the authorized scope of expert opinion evidence. Thus, there was no error.
3. Although Almond urges that the trial court erred in admitting various photographs taken with a digital camera, the record shows that the pictures were introduced only after the prosecution properly authenticated them as fair and truthful representations of what they purported to depict. A trial court's exercise of its discretion in ruling on the admissibility of photographs will not be reversed unless manifestly abused. Williams v. State, 255 Ga. 97, 101(4), 335 S.E.2d 553 (1985). We are aware of no authority, and appellant cites none, for the proposition that the procedure for admitting pictures should be any different when they were taken by a digital camera. See Ray v. State, 266 Ga. 896, 897(1), 471 S.E.2d 887 (1996) (videotapes admissible with same limitations and on same grounds as photographs). Therefore, the trial court did not abuse its discretion by allowing the photos into evidence here.
4. The State introduced evidence that Almond was wearing a camouflage jumpsuit when he shot the victim and then fled to his mother's nearby house, but that, upon exiting her residence some time later, he had on different clothing. When officers searched a garbage truck carrying a trash bag that had been picked up outside the house, they discovered a jumpsuit and numerous papers bearing appellant's name. Some of the papers were official documents connected with his previous drug conviction. The trial court admitted the jumpsuit and all of the papers into evidence, but instructed the jury to consider them only for the limited purpose of identifying Almond as the guilty party. He contends that admission of such of those documents as related to his commission of a previous crime placed his character into evidence.
There was a substantial connection between the evidence of Almond's past crime and his present guilt. Compare Jones v. State, 257 Ga. 753, 363 S.E.2d 529 (1988); Merritt v. State, 255 Ga. 459, 460(2), 339 S.E.2d 594 (1986); Richardson v. State, 199 Ga.App. 10, 11(2), 403 S.E.2d 877 (1991). The evidence from the trash bag had been collected in connection with the investigation of the crimes and was in the possession of the prosecution only because someone had discarded it. Since Almond contended that another named individual was guilty, his identity as the perpetrator was a crucial disputed issue. Relevant evidence which supports the inference that he committed the crimes would be admissible, even though it might incidentally impugn his character. Duck v. State, 250 Ga. 592, 598(4), 300 S.E.2d 121 (1983). Also, proof that Almond subsequently sought to conceal his conduct and identity by abandoning the clothing and other items that he had in his possession at the time of the shooting was relevant. See James v. State, 68 Ga.App. 765, 768(2), 24 S.E.2d 149 (1943). The discovery of a jumpsuit in a trash bag is not necessarily incriminating. Considering all of the circumstances, however, including the bag's connection with the home of appellant's mother and the contemporaneous discovery of a number of documents bearing his name, the discarded article of clothing supports the inference that he was the shooter. Because the items found in the trash bag collectively identify Almond as the perpetrator of the crimes for which he was being tried, they were admissible even if they incidentally placed his character into *806 evidence. See Ledesma v. State, 251 Ga. 885, 888(5)(a), 311 S.E.2d 427 (1984); Duck v. State, supra at 598(4), 300 S.E.2d 121; James v. State, supra at 768(2), 24 S.E.2d 149.
Judgments affirmed.
All the Justices concur.
