1. Having reviewed the evidence in the light most favorable to the jury's determination, we conclude that a rational trier of fact could have found the defendant guilty of felony murder beyond a reasonable doubt. Jackson v. Virginia, 443 U. S. 307 (99 SC 2781, 61 LE2d 560) (1979); Crawford v. State, 245 Ga. 89, 90 ( 263 SE2d 131) (1980). 2. Contrary to Lott's sole enumeration of error, the trial court's charge clearly and unambiguously instructed the jury that they could return a verdict of felony murder only on finding Lott was engaged in the commission of a felony at the time of the homicide, and that the state contended Lott was engaged in the felony of aggravated assault when he killed the victim. Harper v. State, 157 Ga. App. 480, 481 (1) ( 278 SE2d 28) (1981). Harry D. Dixon, Jr., District Attorney, John A. Rumker, Assistant District Attorney, Michael J. Bowers, Attorney General, Susan V. Boleyn, Senior Assistant Attorney General, Robert D. McCullers, Staff Attorney, for appellee. |
