Convicted of felony murder1 for the stabbing death of her companion, Robert Busbee, appellant contends on appeal only that the evidence adduced at trial was not sufficient to support the conviction. We disagree and affirm.
The evidence presented by the State authorized the jury to find that appellant and the victim had a relationship in which mutual physical abuse was frequent and public. On the occasion of the killing, appellant and Busbee had been engaged in an earlier altercation and Busbee locked her out of the room they were sharing in a rooming house. An eyewitness testified that she watched appellant use a spoon to gain entrance to the room, then entered the room along with *197appellant and two other women, finding Busbee asleep with his back to the door. According to the witness, appellant picked a knife up and, without a word, leaned over Busbee and stabbed him once in the chest. The witness described the knife and noted that when appellant pulled it out of Busbee’s wound, the point was bent. A. knife matching the witness’ description was found at the scene and a medical witness testified that the knife’s characteristics, including the bent point, were consistent with Busbee’s wound.
Decided April 30, 1992. Leon Larke, for appellant. Michael C. Eubanks, District Attorney, Nancy J. Berger, Richard E. Thomas, Assistant District Attorneys, Michael J. Bowers, Attorney General, Robert D. McCullers, Staff Attorney, for appellee.Although appellant presented evidence contrary to that of the State, including her testimony that she stabbed Busbee as he physically attacked her and testimony from an expert that appellant was, at the time of the stabbing, suffering from the Battered Woman Syndrome, the evidence presented by the State was sufficient to authorize a rational trier of fact to find appellant guilty of felony murder beyond a reasonable doubt. Jackson v. Virginia, 443 U. S. 307 (99 SC 2781, 61 LE2d 560) (1979); Stoudemire v. State, 261 Ga. 49 (1) (401 SE2d 482) (1991). Appellant’s complaint that the jury should have believed her witnesses rather than the State’s witnesses is controlled adversely to her by the principle that the credibility of witnesses is a question for the jury. Moore v. State, 255 Ga. 148 (335 SE2d 868) (1985).
