PEREZ
v.
The STATE.
No. S06A0774.
Supreme Court of Georgia.
October 30, 2006.
Robert William Lenzer, Thomas Patrick Lenzer, Lenzer & Lenzer, Norcross, for Appellant.
Daniel J. Porter, Dist. Atty., Thurbert E. Baker, Atty. Gen., Edwina M. Watkins, Asst. Atty. Gen., for Appellee.
*31 THOMPSON, Justice.
Defendant Alvaro Antonio Perez was convicted of malice murder, aggravated assault and possession of a knife during the commission of a felony.[1] On appeal, he asserts trial counsel was ineffective because he selected a counselor, instead of a psychologist or psychiatrist, to testify at trial in support of his insanity defense. He also asserts that the aggravated assault conviction should be vacated because it merged with the conviction for malice murder. We do not find ineffective assistance of counsel. We do find, however, that the evidence was insufficient to prove Perez guilty of aggravated assault beyond a reasonable doubt.
Perez became romantically involved with Nidia Laverde in the fall of 2000; the couple planned to be married in February 2001. However, Laverde became unhappy with Perez and called off the wedding. On February 27, 2001, Perez went to Laverde's house. He argued with Laverde, took a knife from the kitchen, and fatally stabbed her. Fleeing the scene in Laverde's car, which he wrecked a short distance away, Perez went to a nearby department store where he purchased, and changed into, a new set of clothes. Perez then went to a bar, quaffed six beers, and called 911, reporting that he had just killed Laverde.
The police apprehended Perez and took him to Laverde's house. They found Laverde's body with a five-inch knife blade embedded in her neck, just above the sternum. She also had other stab wounds on her neck and chest, some of which were made by another knife recovered from the scene.
Perez was taken to the police station, where he gave a videotaped statement. In the statement, Perez told police that Laverde had informed him that she was breaking off the relationship and getting back together with her ex-husband; and that she eventually slapped Perez and called him "stupid." Perez added that he remembered getting a knife from the kitchen, and seeing Laverde bleeding, but he did not remember killing her.
An examination of the victim's body revealed that she suffered three wounds to the neck: two shallow wounds and one deep, five-inch wound above the sternum which pierced her aorta and caused her death. She also suffered eight superficial wounds to the chest. It appears that the neck wounds were made by a five-inch blade, which lodged in the victim, and that the chest wounds were made by a knife with a small forked tip. These wounds consisted of two points, "with skin in between them that had not been injured."
At trial, the medical examiner opined that the neck wounds were inflicted first; that the fatal wound rendered the victim unconscious within 10 or 15 seconds; and that the victim bled to death a few minutes later. He added that the neck wounds and chest wounds were probably made at separate times. In this regard, he surmised that the superficial chest wounds may have been inflicted after the neck wounds to probe the victim to determine if she was dead.
1. Defendant asserts that trial counsel was ineffective because he relied on the testimony of Nancy Ann Manley, Ed. D., a licensed professional counselor, to carry the day with regard to defendant's insanity defense. In this regard, defendant posits that he would have been able to convince the jury that he was insane if defense counsel had sought the expertise of a licensed psychologist or psychiatrist.
To prevail on a claim of ineffective assistance of trial counsel under Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984), a defendant must *32 show that counsel's "performance was deficient and that, but for that deficient representation, there is a reasonable probability that the proceeding would have ended differently. [Cit.]" Silvers v. State, 278 Ga. 45, 46(2), 597 S.E.2d 373 (2004). To meet this burden, a defendant must overcome the strong presumption that his counsel's representation fell within the wide range of reasonable professional conduct. Id. Defendant cannot overcome that presumption. First of all, an insanity defense does not require the expert testimony of a psychologist or psychiatrist. See Motes v. State, 256 Ga. 831, 832, 353 S.E.2d 348 (1987) (insanity defense does not require expert testimony for presentation to a jury). Second, it was shown that, prior to this case, Dr. Manley had conducted forensic evaluations, sometimes at the request of a court, more than 25 times; and she had been qualified as an expert in forensic counseling between 8 and 10 times. Thus, it cannot be said that defense counsel was deficient simply because he presented an insanity defense via a licensed professional counselor instead of a psychologist or psychiatrist.
2. In Williams v. State, 279 Ga. 154, 611 S.E.2d 19 (2005), the victim was found with a four-inch knife blade lodged in her neck. She also suffered small incised wounds on her forehead and neck, and pinpoint defensive wounds on one hand. Williams was convicted of malice murder and aggravated assault. On appeal, we vacated the aggravated assault conviction, finding that the same evidence was used to prove malice murder and aggravated assault.
Perez asserts that, as in Williams, the aggravated assault conviction should be vacated because it merged as a matter of fact with the malice murder conviction. On the other hand, the State argues that the evidence established two separate and complete crimes and that the first crime (malice murder) was completed when the second (aggravated assault) was perpetrated upon the victim. See Farley v. State, 277 Ga. 622, 623(2), 593 S.E.2d 328 (2004); Stockford v. State, 276 Ga. 241, 243(3), 575 S.E.2d 889 (2003). However, we need not resolve this issue because it is clear that the evidence is insufficient to find Perez guilty beyond a reasonable doubt of aggravated assault. Simply put, the evidence does not prove that Perez intended to violently injure the victim when he probed her, or that the victim, who was unconscious if not dead at that time, was placed in reasonable apprehension of being violently injured. See Gamble v. State, 235 Ga.App. 777, 780(3), 510 S.E.2d 69 (1998) (citing Smith v. Hardrick, 266 Ga. 54, 56, 464 S.E.2d 198 (1995)). See also OCGA §§ 16-5-20(a); 16-5-21(a).
3. The evidence was sufficient to enable any rational trier of fact to find Perez guilty beyond a reasonable doubt of malice murder and possession of a knife in the commission of a felony. Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979). However, the evidence was insufficient to find Perez guilty beyond a reasonable doubt of aggravated assault.
Judgment affirmed in part and reversed in part.
All the Justices concur.
