THOMPSON, Chief Justice.

Appellant Jessie Ben Mathis was convicted of felony murder, armed robbery, aggravated assault and possession of a weapon during the commission of a crime in connection with the shooting death of Souphoth Thammavongsa.1 Appellant's motion for new trial was denied, and he now appeals that decision and his conviction. We find no reversible error and affirm.

Viewed in the light most favorable to the verdict, the jury was authorized to find that on October 19, 2008, appellant and co-conspirators Gary Kilgore and Dexter Armstrong entered the Thai Video store shouting "ATF, get on the floor!" Store customers were forced to the floor and the owner of the store was shot and killed. The assailants, including appellant, then forced the owner's son to the back of the store where they showed him the bloody gun and his father's body and threatened to shoot him if he did not produce additional money. When this proved unsuccessful, appellant and the others threatened and robbed the customers before leaving the store.

Shortly after fleeing the crime scene, Armstrong met with his then-girlfriend, Theresa Anderson, gave her close to $1,300, which he asked her to hold for him,2 and told her that he, Kilgore and appellant had robbed the video store and that Kilgore had shot and killed the owner. Anderson later told a friend about this exchange and the friend called police. Relying on this tip, police arrested appellant and the others, and detained Anderson for questioning. Anderson subsequently disclosed Armstrong's statements, including those implicating appellant and Kilgore. In addition, two witnesses identified appellant as one of the assailants through photographic lineups and made in-court identifications of him at trial.

1. We conclude the evidence was sufficient to enable a rational trier of fact to find appellant guilty beyond a reasonable doubt of the crime of felony murder and the other crimes for which he was convicted. Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979).

2. Appellant claims the trial court erred in failing to question or excuse an allegedly sleeping juror. During presentation of the State's case, appellant's counsel expressed concern to the court that one of the jurors appeared to be sleeping. In response, the court instituted a "buddy system" between jurors to have them help each other stay awake. Later in the trial, counsel revisited the issue, asking that the juror in question be replaced with an alternate. The State objected, arguing there was no proof that the juror had been sleeping and the trial court denied appellant's motion. However, prior to jury deliberations at the end of trial, the court gave appellant's counsel the opportunity to renew her motion to replace the juror and she declined. As counsel made no contemporaneous request for the trial court to conduct an inquiry and later declined to move to excuse the juror, we find this issue has been waived. See Smith v. State, 277 Ga. 213, 216, 586 S.E.2d 639 (2003); Joyner v. State, 208 Ga. 435, 438, 67 S.E.2d 221 (1951).

Even assuming this issue is properly before the Court, we find no error. Pursuant to OCGA § 15-12-172,3 a trial court is statutorily vested with the discretion to replace a juror with an alternate at any time during the proceedings as long as the court has a sound legal basis to do so. Smith v. State, 284 Ga. 17, 22, 663 S.E.2d 142 (2008); Brooks v. State, 281 Ga. 14, 18, 635 S.E.2d 723 (2006). Further, this court will not interfere with a trial court's decision regarding removal of a juror from a panel absent an abuse of that court's discretion. Chance v. State, 291 Ga. 241, 243, 728 S.E.2d 635 (2012); Pinkins v. State, 243 Ga.App. 737, 740(3), 534 S.E.2d 192 (2000). When confronted with a situation involving a juror who appears to have fallen asleep during trial, counsel has a duty to bring the matter to the attention of the trial court and the trial court has a duty to awaken the juror. Smith, supra; Foster v. State, 255 Ga. 425(2), 339 S.E.2d 256 (1986). Here, the trial court took prompt action when the allegedly sleeping juror was brought to its attention by reminding all of the jurors to stay awake and instructing them to help each other stay awake.

Appellant argues that in addition to the actions taken, the trial court was required to conduct an inquiry to determine whether the juror had, in fact, been sleeping or was incapacitated. We disagree. Given that the only juror irregularity alleged in this case consisted of a relatively brief, single act of dozing, we find no abuse of discretion on the part of the trial court in concluding that its immediate remedial actions were sufficient. See Smith, supra; Williams v. State, 190 Ga.App. 361, 362, 378 S.E.2d 886 (1989). See also Lamons v. State, 255 Ga. 511, 512, 340 S.E.2d 183 (1986) (some irregularities in juror conduct are inconsequential). Compare Gibson v. State, 290 Ga. 6, 10, 717 S.E.2d 447 (2011) (trial court properly removed juror who repeatedly slept through presentation of evidence). As there appears to have been no sound legal basis to replace the juror, the trial court did not abuse its discretion in denying appellant's request that it do so. See Herring v. State, 224 Ga.App. 809, 811-12, 481 S.E.2d 842 (1997).

3. Appellant additionally claims his trial counsel was ineffective for failing to request that the trial court conduct an inquiry into whether the juror was sleeping. To prevail on a claim of ineffectiveness, appellant must show both that counsel's performance was deficient and that the deficient performance was prejudicial to his defense. Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984); Smith v. Francis, 253 Ga. 782, 783, 325 S.E.2d 362 (1985). If appellant fails to meet his burden of proving either prong of this two prong test, the reviewing court need not examine the other prong. Strickland, supra, 466 U.S. 668, 697 at (IV), 104 S.Ct. 2052. To satisfy the first prong, appellant must overcome the strong presumption that counsel's performance fell within a "wide range of reasonable professional conduct," and that counsel's decisions were "made in the exercise of reasonable professional judgment." Id. at 689-690, 104 S.Ct. 2052. Moreover, the reasonableness of counsel's conduct is examined from counsel's perspective at the time of trial and under the particular circumstances of the case. Smith, supra at 784, 325 S.E.2d 362.

Appellant argues that without the information an inquiry could have provided, trial counsel was unable to make an informed decision on whether to renew her motion to remove the juror when this issue was revisited by the trial court at the conclusion of the trial. At the motion for new trial hearing, appellant's counsel testified she chose not to renew the motion due to the fact there had been no further incidents involving the juror and the trial court had spoken to the juror and taken remedial action. However, counsel was not questioned as to why she initially chose to accept the trial court's remedial efforts without requesting additional inquiry. In the absence of evidence to the contrary, "counsel's decisions are presumed to be strategic and thus insufficient to support an ineffective assistance of counsel claim." Washington v. State, 285 Ga. 541, 543, 678 S.E.2d 900 (2009). In any event, this Court has determined that no further inquiry by the trial court was necessary under the circumstances presented in this case, see Division 2, supra, and we find trial counsel's failure to make such a request does not constitute deficient performance. See Washington, supra at 544, 678 S.E.2d 900. As appellant has failed to satisfy the first Strickland prong with regard to this enumeration of error, his ineffective assistance of counsel claim lacks merit.

4. Appellant asserts the trial court erred in allowing Anderson to testify about Armstrong's statements to her pursuant to the co-conspirator exception to the hearsay rule which provides that "[a]fter the fact of conspiracy is proved, the declarations by any one of the conspirators during the pendency of the criminal project shall be admissible against all." OCGA § 24-3-5.4 In order for this exception to apply, the State must show the existence of a conspiracy without regard to the declarations of the co-conspirator. Heard v. State, 287 Ga. 554, 559, 697 S.E.2d 811 (2010). Existence of a conspiracy may be shown by direct or circumstantial evidence. Brooks, supra, 281 Ga. at 15, 635 S.E.2d 723. Further, "[c]onduct which discloses a common design, even without proof of an express agreement between the parties, may establish a conspiracy." Heard, supra at 559-560, 697 S.E.2d 811.

Here, evidence was presented that appellant and his co-defendants knew each other prior to the crime, they went to the Thai Video store together, Kilgore shot the owner who put a gun to Armstrong's head, and they worked together to rob the other victims before fleeing the store together. These facts show a common design and purpose to commit the robbery and establish the existence of a conspiracy. See Freeman v. State, 273 Ga. 137, 139, 539 S.E.2d 127 (2000). Armstrong's concealment of the robbery proceeds in Anderson's car at the time he made his statements establishes that the criminal enterprise was not at an end. Because there was evidence independent of the challenged statements to establish the conspiracy and the conspiracy was still in the concealment stage when the statements were made, the State met its burden under OCGA § 24-3-5 and the trial court did not err in concluding that Armstrong's statements were admissible as those of a co-conspirator. See Young v. State, 291 Ga. 627(3), 732 S.E.2d 269 (2012); Allen v. State, 288 Ga. 263(4), 702 S.E.2d 869 (2010).

5. Likewise, we find no error in the trial court's refusal to suppress appellant's pretrial and in-court identifications by State witnesses. Appellant claims that in the photographic array used by the State, his picture was visibly darker than the other pictures and his hairstyle and complexion were noticeably different. He argues that, as a result, his picture stood out from the others and equated to authorities telling the witnesses, "[t]his is our suspect." See Davis v. State, 286 Ga. 74, 76(2)(a), 686 S.E.2d 249 (2009). Further, appellant asserts that under the totality of the circumstances, the suggestiveness of the State's lineup gave rise to a substantial likelihood of his misidentification by the witnesses.

"Convictions based on eyewitness identification at trial following a pretrial identification by photograph will be set aside only if the photographic identification procedure was so impermissibly suggestive as to give rise to a very substantial likelihood of irreparable misidentification. (Citations omitted)." Marshall v. State, 285 Ga. 351, 352, 676 S.E.2d 201 (2009). Based on the evidence in the record, we find nothing inherently suggestive or otherwise improper about the photographic lineups in this case. The lineup which included appellant consisted of six black males with goatees and similar hairstyles, none noticeably different from appellant or from each other. Witnesses were provided with several sets of photos rather than a single lineup, were not told that a suspect was, in fact, depicted in any of the lineups and thus were not led to an "all but inevitable identification" of appellant. Clark v. State, 271 Ga. 6, 12, 515 S.E.2d 155 (1999).

Nor do we find a substantial likelihood of irreparable misidentification of appellant by the State's witnesses due to the photographic lineup. Factors to be considered in determining admissibility of eyewitness identifications, include: (1) a witness' opportunity to view the accused at the time of the crime; (2) the witness' degree of attention; (3) the accuracy of the witness' prior description of accused; (4) the witness' level of certainty at the confrontation; and (5) the length of time between the crime and the confrontation. Thomason v. State, 268 Ga. 298, 303-304, 486 S.E.2d 861 (1997). Two separate witnesses identified appellant within weeks of the crime. Both testified they spent time looking at the assailants threatening their lives during the 30-45 minute robbery. Moreover, although each gave only a general description to police immediately after the robbery, both witnesses identified appellant from the photographic array with certainty.

6. Finally, appellant contends the trial court erred in denying his motion for directed verdict on two of the aggravated assault counts.5 Appellant asserts these aggravated assault counts should have been dismissed because the indictment charged him with assaulting these victims "with intent to rob," thus requiring both an intent to rob on his part and reasonable apprehension of receiving bodily injury on the part of the victims. With respect to these two counts, neither of the named victims testified to having a reasonable apprehension of bodily injury. Indeed, one victim whose cell phone was stolen testified he was not afraid during the commission of the crime, while the other victim who was hiding during the robbery had no items taken from him by the assailants.

Aggravated assault requires an assault coupled with the intent to rob, however, there is no provision that property actually be taken. Lucky v. State, 286 Ga. 478, 482, 689 S.E.2d 825 (2010). Nor does the fact that a victim claims to have been unafraid preclude a finding of reasonable apprehension. Bates v. State, 275 Ga. 862, 865, 572 S.E.2d 550 (2002). Here, both men got down on the floor when ordered to do so by the armed intruders, both heard gun shots, and both complied with the demand that they stay put until after the intruders left. In addition, one victim surrendered his cell phone as demanded and stated that he remained on the floor because he did not want to be killed. Accordingly, we find no error in the trial court's denial of appellant's motion for directed verdict on these two counts.

Judgment affirmed.
