MANRIQUEZ
v.
The STATE.
No. S09A0857.
Supreme Court of Georgia.

*651 Sharon L. Hopkins, Augusta, for appellant.

CARLEY, Presiding Justice.
A jury found Miguel Manriquez guilty of malice murder, felony murder, aggravated assault and possession of a firearm during the commission of a felony. The trial court entered judgments of conviction and sentenced him to life imprisonment for malice murder, twenty years in prison for aggravated assault and five years confinement for the firearm offense. The felony murder verdict was vacated by operation of law. See Malcolm v. State, 263 Ga. 369, 372(5), 434 S.E.2d 479 (1993). Manriquez appeals after the denial of a motion for new trial.[*]
1. Construed most strongly in support of the verdicts, the evidence shows that Manriquez shot and killed Ezequiel Nunez, and threatened Joe Hall with a gun. The evidence was sufficient for a rational trier of fact to find Manriquez guilty beyond a reasonable doubt of murder and the other offenses. Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979).
2. Manriquez contends that his trial counsel was ineffective in failing to call four witnesses who gave descriptions of the shooter that differed from the description given by Hall. To prevail on an ineffectiveness claim, a defendant has the burden of establishing that his counsel's performance was deficient and that the deficiency prejudiced his defense. Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d *652 674 (1984); Hunt v. State, 278 Ga. 479, 480, 604 S.E.2d 144 (2004).
When a defendant claims that trial counsel performed deficiently in failing to [call] a witness for trial, the defendant may not rely on hearsay and speculation, including prior unsworn statements, to prove the prejudice prong of his ineffectiveness claim. [Cits.]
Brooks v. State, 285 Ga. 246, 250(4)(c), 674 S.E.2d 871 (2009). Rather, the defendant must introduce either testimony from the uncalled witness or a legally recognized substitute for his testimony, such as an affidavit. Brooks v. State, supra; Lupoe v. State, 284 Ga. 576, 578(3)(b), 669 S.E.2d 133 (2008); Dickens v. State, 280 Ga. 320, 322(2), 627 S.E.2d 587 (2006). Here, Manriquez did not call the four witnesses to testify at the motion for new trial hearing, or present a legally acceptable substitute for their testimony, and instead relied on copies of their unsworn statements to police. Under these circumstances, Manriquez has failed to carry his burden of proving that he was prejudiced by counsel's failure to call the witnesses at trial. See Brooks v. State, supra; Lupoe v. State, supra; Dickens v. State, supra; Hudson v. State, 277 Ga. 581, 584-585(4)(a), 591 S.E.2d 807 (2004).
Moreover, it is well established that counsel's decisions as to which defense witnesses to call are matters of trial strategy and tactics. Simpson v. State, 277 Ga. 356, 359(4)(c), 589 S.E.2d 90 (2003). In this case, Manriquez did not call his trial attorney to testify at the motion for new trial hearing. Consequently, he made no affirmative showing that the purported deficiency in the lawyer's representation was indicative of ineffectiveness, as opposed to being an example of a conscious, deliberate and reasonable trial strategy. See Hayes v. State, 279 Ga. 642, 645(3), 619 S.E.2d 628 (2005); Prince v. State, 277 Ga. 230, 234(3), 587 S.E.2d 637 (2003).
Judgment affirmed.
All the Justices concur.
