Patrick G. Longhi, Atlanta, for Samuel Eugene Daniel.
*735 Paul L. Howard, Jr., Dist. Atty., Gina C. Marshall, Asst. Dist. Atty., Michael J. Bowers, Atty. Gen., Patricia Beth Attaway, Asst. Atty. Gen., and Paula K. Smith, Senior Asst. Atty. Gen., Atlanta, for State.
CARLEY, Justice.
A jury found Samuel Daniel guilty of malice murder and the trial court sentenced him to life imprisonment. He appeals from the judgment of conviction and sentence entered on the guilty verdict.[1]
1. The victim, who was the current boyfriend of Daniel's former girlfriend, was fatally stabbed. Although there were no eyewitnesses to his homicide, the evidence showed that Daniel harbored animosity toward the victim. Daniel had been stalking his former girlfriend and, when he attacked her on the day before the murder, the victim came to her rescue and struck Daniel. Daniel threatened to kill the victim. The next day, Daniel displayed a knife to a friend and again made threats to kill the victim. After the discovery of the victim's body, Daniel made a statement admitting that he fought with the victim, but also claiming that he lost consciousness and did not remember what had happened. This evidence authorized a rational trier of fact to find proof of Daniel's guilt of malice murder beyond a reasonable doubt. Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979).
2. Daniel enumerates as error the admission into evidence of his statement. According to him, the trial court should not have admitted the statement because, at the time he made it, he was confused and his judgment was impaired because of the blow the victim struck the day before. A review of the record shows that the trial court conducted a Jackson-Denno hearing, at which the State called the officer to whom the statement was given and this officer's testimony authorized the trial court's conclusion that Daniel gave the statement freely and voluntarily. "`Unless clearly erroneous, a trial court's findings relating to the admissibility of an incriminating statement will be upheld on appeal.' [Cit.]" LeMay v. State, 265 Ga. 73(2), 453 S.E.2d 737 (1995). Daniel offered nothing to rebut the officer's testimony and, contrary to Daniel's contention, the State was not required to corroborate the officer's testimony by proffering a videotape of the session at which the statement was made. The trial court was authorized to base its ruling on the testimony and credibility of the officer himself. See generally Washington v. State, 243 Ga. 329, 333(2), 253 S.E.2d 719 (1979). It follows that this enumeration of error is without merit.
3. Daniel urges that the trial court erred in ruling that, in the event he relied upon expert mental health evidence, he would be required to submit to an independent mental health evaluation by an expert of the State's choosing. In Lynd v. State, 262 Ga. 58, 64(11), 414 S.E.2d 5 (1992), we held that a defendant in a criminal case "can no more present psychiatric testimony without submitting to an examination by a state-selected psychiatrist than he may testify at trial without submitting to a cross-examination." Accordingly, this enumeration of error is without merit.
Judgment affirmed.
All the Justices concur.
