v.
The STATE.
No. S08A0233.
Supreme Court of Georgia.
February 11, 2008.
*231 Carl P. Greenberg, Atlanta, for appellant.

CARLEY, Justice.
After a jury trial, Ambrocio Valdivia was convicted of two counts of malice murder and one count of aggravated assault with a deadly weapon. The trial court sentenced Valdivia to two life sentences for the murders and to a consecutive 20-year term of imprisonment for aggravated assault. Valdivia filed a motion for new trial, after the denial of which he now brings this appeal.[*]
1. The three victims were attending a party at an apartment complex. They knocked on the door of Valdivia's unit, in the mistaken belief that they could buy beer at that location. Prosecution witnesses testified that Valdivia shot all three men and fled. Two of them died, and the third was wounded. Valdivia was arrested a short time later, not far from the scene of the shootings. In his post-arrest statement, he claimed that he ran away after the victims began to beat him.
When construed most strongly in support of the jury's verdicts, the evidence is sufficient to authorize a rational trier of fact *232 to find proof beyond a reasonable doubt that Valdivia was guilty of the two murders and aggravated assault with a deadly weapon. Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979).
2. Valdivia contends that the trial court failed to insure that the State exercised its peremptory jury strikes in a racially neutral manner. See Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986). However, the record demonstrates that he never raised this issue below. "`[A]ny claim under Batson should be raised prior to the time the jurors selected to try the case are sworn.' [Cit.]" Greene v. State, 260 Ga. 472, 473(1), 396 S.E.2d 901 (1990).
The transcript shows that the trial court, on its own motion, asked the prosecutor to explain his strikes. After hearing the reasons that were presented, the trial court expressed concern, but concluded by stating "let's move forward at this time." Valdivia did not object, and the jury was sworn thereafter. "Because [he] failed to raise this issue prior to the time the jurors were sworn, he did not properly preserve it for our review." Greene v. State, supra.
3. Valdivia enumerates as error the trial court's charge that, in assessing the testimony of the witnesses who identified him as the shooter, the jury could consider the level of certainty they expressed in naming him. The instruction was erroneous. Brodes v. State, 279 Ga. 435, 614 S.E.2d 766 (2005). However, it also was requested by the defense. Thus, even though "the charge was incorrect, such invited error is not grounds for reversal. [Cits.]" Barnes v. State, 269 Ga. 345, 356(19), 496 S.E.2d 674 (1998). Moreover, since the witnesses who identified Valdivia as the shooter had known him previously, some for many years, the instruction was harmless. Jones v. State, 282 Ga. 306, 307(4), 647 S.E.2d 576 (2007).
Judgments affirmed.
All the Justices concur.
