BLACKWELL, Justice.

Paris Leroy Johnson, Jr. was tried by a Walton County jury and convicted of the murder of Antonio Milton. Following the denial of his motion for new trial, Johnson appeals, contending that the trial court erred when it failed to charge the jury on voluntary manslaughter as a lesser included offense, when it allowed the State to cross-examine him about his failure to come forward and make a statement, and when it admitted testimony that impermissibly placed his character into evidence. Upon our review of the record and briefs, we see no error and affirm.1

1. Viewed in the light most favorable to the verdicts, the evidence shows that Milton was dating Jessica Smith, who remained friendly with Johnson, her ex-boyfriend. Johnson disapproved of Smith's new relationship, told her that he felt like hurting and killing somebody, and sent her this text message: "[I]f I can't have you, nobody can." On the evening of October 9, 2009, Smith went to the residence of Johnson and his mother to take a pregnancy test. When Smith started to leave, Johnson became angry, and when Milton came to the front door, Johnson became even angrier, slammed the door, and armed himself with a handgun. Smith convinced Johnson to put the gun away.

While Smith and Milton were talking at the door, Johnson walked past them to a truck where he spoke to some men about a marijuana transaction. It is undisputed that the only words exchanged at any time between Milton and Johnson were Milton's request for a cigarette and Johnson's negative answer. After Johnson twice returned to the house, he went back outside, struck Milton in the head with a baseball bat, chased him into the parking lot, knocked him to the ground, and struck him with the bat several more times. Milton was unarmed and had not threatened Johnson or made any aggressive movements toward him.

When the men in the truck asked Johnson why he had attacked Milton, Johnson said that Milton "shouldn't have come over here." Johnson told a neighbor that he had just knocked somebody out and not to call anyone, and he then dragged Milton across the parking lot. After police officers arrived and told Johnson that he would be detained so as to remove him from the crime scene, he responded that "it don't matter anyways, I'm going to jail[,]" and "I knew something was going to happen because he kept harassing me."

Milton died two days later, and the medical examiner testified that the cause of death was severe blunt-force trauma to the head from at least two impacts. Johnson testified that he had hit Milton once with the bat to scare him away because Smith had told Johnson that Milton previously made threats about harming Johnson and, as a result, Johnson feared for his own safety and that of his mother. But Johnson admitted that while Milton was outside Johnson's home, Milton did not yell at Johnson, threaten him or his mother, make aggressive movements, or pull a weapon.

Although Johnson does not dispute that the evidence is sufficient to sustain his conviction, we have independently reviewed the record, and we conclude that the evidence adduced at trial, including the eyewitness testimony of Smith and of two men who were in the truck, was sufficient to authorize a rational trier of fact to find beyond a reasonable doubt that Johnson was guilty of murder. Jackson v. Virginia, 443 U.S. 307, 319(III)(B), 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979). See also Glover v. State, 291 Ga. 152, 153(1), 728 S.E.2d 221 (2012).

2. We next consider the contention that the trial court should have charged the jury, as Johnson requested, on voluntary manslaughter as a lesser included offense. A trial court is required to give such a charge on request "if there is slight evidence showing that the victim seriously provoked the defendant, causing the defendant to kill the victim `solely as the result of a sudden, violent, and irresistible passion,' OCGA § 16-5-2(a)." Merritt v. State, 292 Ga. 327, 331(2), 737 S.E.2d 673 (2013) (citation and punctuation omitted). The evidence in this case shows, at most, that Milton had told Smith on prior occasions that he might harm Johnson, but Johnson was not present at the time of those threats. See Howard v. State, 288 Ga. 741, 745(4), 707 S.E.2d 80 (2011). It is undisputed that, while Milton was in Johnson's presence on October 9, 2009, Milton did not use threatening words, make aggressive movements, or pull a weapon. Under these circumstances, Johnson's response to the provoking incident was objectively unreasonable, and nothing in the evidence required a charge on voluntary manslaughter. See id. at 746(4), 707 S.E.2d 80; Robinson v. State, 129 Ga. 336, 338(2), 58 S.E. 842 (1907).

3. We turn now to the claim that the trial court improperly allowed the State to cross-examine Johnson about his failure to come forward and make a statement. Soon after the crime occurred, Johnson waived his Miranda2 rights, was interviewed by a police investigator, and did give a statement. During cross-examination of Johnson, the prosecuting attorney elicited testimony that at no point during the interview or at any other time did Johnson ever indicate that he feared for his safety or the safety of his mother. Johnson then agreed that, at a hearing two weeks before trial, he testified for the first time about being afraid for his safety. And the prosecuting attorney asked him, "So, almost a year and a half went by before you ever mentioned anything about being in fear of your safety?" Johnson argues that by this cross-examination, especially the question just quoted, the State improperly commented on his silence and failure to come forward after his pretrial statement.

At trial, however, Johnson's lawyer did not object to the cross-examination of which he now complains until a bench conference that he requested two questions later. See Izzo v. State, 265 Ga.App. 143, 143(1), 592 S.E.2d 915 (2004); Hayward v. State, 258 Ga.App. 566, 569(2)(a), 574 S.E.2d 646 (2002); Jolly v. Zarella, 252 Ga.App. 130, 131-132, 555 S.E.2d 798 (2001). Georgia "has long followed the contemporaneous objection rule, which provides that counsel must make a proper objection on the record at the earliest possible time to preserve for review the point of error." State v. Larocque, 268 Ga. 352, 353, 489 S.E.2d 806 (1997) (citation omitted). See also Whitehead v. State, 287 Ga. 242, 246(2), 695 S.E.2d 255 (2010) (standard practice requires a party to make an objection and obtain a ruling "before or as the evidence is admitted"). "The purpose of requiring a timely objection is to avoid placing improper information before the jury. Removing from a jury's consideration evidence it has heard is difficult at best and well nigh impossible after it has had time to sink in." Martin v. State, 281 Ga. 778, 780(2), 642 S.E.2d 837 (2007) (citations and punctuation omitted). Because Johnson did not object at the time of the complained-of cross-examination, he has waived appellate review of this issue. See Sanders v. State, 289 Ga. 655, 659(2), 715 S.E.2d 124 (2011).

Even if Johnson had made a timely objection, "[i]t was not improper for the prosecutor to cross-examine [him] regarding his failure to mention [his fear] to officers or others when he made his statement or at any other time before trial." Stringer v. State, 285 Ga. 842, 845-846(4), 684 S.E.2d 590 (2009) (citations omitted). See also Kendrick v. State, 287 Ga. 676, 677-678(2), 699 S.E.2d 302 (2010). Johnson chose to speak to the investigating officer without ever invoking his right to remain silent. Under the circumstances, the State's questions were proper inquiries into the inconsistency between his pre-trial statement and his testimony at trial. Stringer, 285 Ga. at 846(4), 684 S.E.2d 590. "If [Johnson] has recently manufactured self-serving and exculpatory evidence, the jury surely was entitled to know of that possibility and weigh it in their deliberations." Id. (citations and punctuation omitted). Moreover, even if we assumed that the State's cross-examination did include improper comments on Johnson's silence, reversal of his conviction would not be warranted because the extensive eyewitness testimony and other evidence that proved his guilt and refuted his claim of self-defense was overwhelming. See Collins v. State, 289 Ga. 666, 668-669, 715 S.E.2d 136 (2011); Pearson v. State, 277 Ga. 813, 817(5)(c), 596 S.E.2d 582 (2004).

4. Finally, we consider the contention that the trial court erroneously allowed impermissible character evidence when it admitted eyewitness testimony about Johnson's alleged involvement in a marijuana transaction.3 The court viewed that evidence as part of the res gestae4 of the crime for which Johnson was being tried. Under the old rules of evidence that apply here, we have said that

Johnson v. State, 264 Ga. 456, 457(1), 448 S.E.2d 177 (1994) (citations and punctuation omitted). A statement of an eyewitness as to what occurred shortly before or shortly after the commission of the murder, even if it shows the commission of an additional uncharged crime, generally was admissible under those rules as relevant res gestae evidence. Roberts v. State, 282 Ga. 548, 551(6), 651 S.E.2d 689 (2007); Johnson, 264 Ga. at 457(1), 448 S.E.2d 177.

In the present case, the challenged testimony was relevant to explain the presence of the truck and the testimony of its owner that he drove to a meeting with Johnson yet did not know him well enough to identify him in court, as well as to explain why Johnson kept leaving his residence, walking past Milton and Smith to the truck, and returning to the residence shortly before the murder. See Roberts, 282 Ga. at 551(6), 651 S.E.2d 689; Shealey v. State, 257 Ga. 437, 438(2), 360 S.E.2d 266 (1987). The challenged testimony was also relevant to Johnson's state of mind because it showed that his concern about Milton was not such that it prevented Johnson from leaving Milton at the front door so that Johnson could arrange a drug deal. See Carter v. State, 269 Ga. 891, 892(3), 506 S.E.2d 124 (1998); Frazier v. State, 257 Ga. 690, 698(16), 362 S.E.2d 351 (1987). Accordingly, the trial court did not err when it admitted testimony about the marijuana transaction even though it incidentally placed Johnson's character in issue. See Roberts, 282 Ga. at 551(6), 651 S.E.2d 689. Moreover, even if the court did err when it admitted the testimony as part of the res gestae of the murder, the error is harmless because, as discussed above in Division 3, the evidence of Johnson's guilt was overwhelming and it is therefore highly probable that the admission of the challenged testimony did not contribute to the verdict. See Walker v. State, 282 Ga. 703, 705(2), 653 S.E.2d 468 (2007).

Judgment affirmed.
