CARLEY, Justice.
A jury found Gearol Bryant guilty of felony murder while in the commission of both an aggravated assault and a theft by taking. The trial court entered its judgment of conviction on the jury verdict, and imposed a sentence of life imprisonment. The trial court denied Bryant's motion for a new trial, and he appeals.[1]
1. Bryant stole jewelry and a handgun from his cousin in Summerville. He pawned the jewelry and, armed with the gun, hitchhiked to Atlanta. Needing a place to stay, he arrived unannounced at the apartment of Dale Ryan, who was an acquaintance. Ryan let him in, and offered him pizza and beer. At some point, Bryant shot Ryan, and then stole Ryan's car and fled to Alabama. When apprehended, Bryant initially denied any involvement in the homicide, claiming that he merely was present in Ryan's apartment when two other men broke in and committed the murder. However, there was no indication of a break-in at Ryan's apartment, and Bryant subsequently changed his story. In his new version of the events, Bryant admitted shooting Ryan, but contended that he did so accidentally and then fled in Ryan's car after panicking. However, this claim was inconsistent with the circumstantial evidence indicating that the homicide was perpetrated methodically, and was not an accidental occurrence. Ryan's body was not randomly situated, as might be expected in the case of an accidental shooting after which the perpetrator fled in panic. When discovered, Ryan's body was lying on his mattress and gave the initial appearance that Ryan died from natural causes while sleeping. It was not until the medical examiner subsequently discovered a gunshot wound in the back of Ryan's head that it became apparent that a homicide had been committed. At trial, Bryant continued to maintain that he shot the victim accidentally, and he also alluded to the possibility that, after he passed out from drinking beer, Ryan may have committed a homosexual assault on him. Construing the evidence most strongly in favor of the verdict, it was sufficient to authorize a rational trier of fact to find proof beyond a reasonable doubt of his guilt of felony murder while in the commission of an aggravated assault upon Ryan and the theft by taking of Ryan's property. Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979).
2. Bryant enumerates as error the admission of evidence that he stole the jewelry and gun from his relative in Summerville. The admissibility of this evidence was challenged in the context of Bryant's pre-trial motion in limine, which the trial court denied. Thus, Bryant has preserved the issue for review, even though he did not object when the evidence was proffered during the course of the trial. Harley-Davidson Motor Co. v. Daniel, 244 Ga. 284, 285(1), 260 S.E.2d 20 (1979).
When he stole the items, Bryant left a note for his cousin indicating that he intended to leave for Atlanta, which he did after pawning the jewelry. Shortly after arriving in Atlanta, Bryant shot Ryan and stole Ryan's car. Although the State was unable to present direct evidence that the weapon used to shoot Ryan was the one which Bryant stole in Summerville, there was circumstantial evidence of that fact, in that the caliber of both guns was the same and there was only a relatively short interval between the theft of the gun and the homicide in Atlanta. Considering the totality of the circumstances, Bryant's commission of *838 the earlier theft "was clearly relevant ... to show where the murder weapon came from." Fleming v. State, 269 Ga. 245, 248(7), 497 S.E.2d 211 (1998). See also King v. State, 230 Ga. 581, 582(2), 198 S.E.2d 305 (1973); Hall v. State, 163 Ga.App. 515, 517(5), 295 S.E.2d 194 (1982). Compare Carter v. State, 261 Ga. 344, 345(3), 404 S.E.2d 432 (1991).
3. The trial court refused to allow an expert to testify that, in his opinion, Bryant suffered from a post-traumatic stress disorder stemming from childhood sexual abuse. Bryant enumerates this evidentiary ruling as error, contending that the excluded testimony was relevant to whether his shooting of Ryan was a justifiable homicide. As defense counsel conceded in the trial court, however, the expert's opinion testimony was "not really going as to a justification defense in this case." Indeed, the testimony could not be admissible for that purpose, since Bryant did not contend that he had a history of being sexually abused by Ryan himself. If Bryant was asserting self-defense, he could show other specific acts of violence committed against him and others by Ryan. See Chandler v. State, 261 Ga. 402, 407(3)(c), 405 S.E.2d 669 (1991). He could not, however, support that defense by the proffer of any evidence based upon the commission of extraneous acts of abuse upon him by anyone other than Ryan. "It would be difficult, if not impossible, for the [S]tate to rebut, refute or test as to credibility, evidence of abuse by third parties." Clenney v. State, 256 Ga. 123, 124-125(3), 344 S.E.2d 216 (1986).
Because Bryant did not assert the defense of delusional compulsion as defined in OCGA § 16-3-3, we need not address the admissibility of the evidence in support thereof. Bryant's mental state resulting from his childhood sexual abuse would have no bearing on whether the gun discharged "by misfortune or accident" and in the absence of any "criminal scheme or undertaking, intention or criminal negligence." OCGA § 16-2-2. Thus, the expert's testimony was not relevant to Bryant's defense of accident. Insofar as the lesser offense of voluntary manslaughter is concerned, the trial court did not preclude Bryant from pursuing the topic of Ryan's alleged sexual assault as provocation for the shooting. Bryant's guilt of voluntary manslaughter was dependent upon whether the jury believed that he had been sexually assaulted by Ryan and, if so, whether a sufficient cooling-off period elapsed between that assault and the shooting. OCGA § 16-5-2(a). As it elucidated neither issue, the trial court properly excluded the opinion of the expert that Bryant suffered from a post-traumatic stress disorder arising from childhood sexual abuse by others. See Lewandowski v. State, 267 Ga. 831, 832(2), 483 S.E.2d 582 (1997).
4. In connection with its charge on voluntary manslaughter, the trial court included an instruction which tracked the language of OCGA § 16-5-2(a). On appeal, Bryant urges that this instruction is unconstitutionally burden-shifting, in that it requires the jury to find a defendant guilty of murder if it determines that a sufficient cooling-off period intervened between the provocation and the homicide.
The record demonstrates that Bryant requested the trial court to charge on the entirety of OCGA § 16-5-2(a). An appellant is estopped to urge error in the giving of a charge which he requested. Roulain v. Martin, 266 Ga. 353, 354(2), 466 S.E.2d 837 (1996). Moreover, this Court has upheld an instruction which follows the language of OCGA § 16-5-2(a) against the contention that it unconstitutionally shifts the burden of proof from the State to the defendant. Barron v. State, 261 Ga. 814, 815(3), 411 S.E.2d 494 (1992); White v. State, 255 Ga. 731, 733(4), 342 S.E.2d 304 (1986). Thus, the trial court did not err by giving that charge in this case.
Judgment affirmed.
All the Justices concur.
