JONES
v.
The STATE.
No. A10A0064.
Court of Appeals of Georgia.
May 11, 2010.
*360 James W. Bradley, Matthew A. Tucker, for appellant.
Tracy G. Lawson, District Attorney, Luana Popescu, Assistant District Attorney, for appellee.
DOYLE, Judge.
Following a jury trial, Harvey Louis Jones, Sr., was convicted of aggravated assault[1] and possession of a weapon during commission of a crime.[2] Jones appeals, claiming that the trial court erred in excluding evidence of threats made by the victim against Jones and his family, and in failing to charge the jury on justification, defense of self and others, misapprehension of fact, and no duty to retreat. For the reasons that follow, we affirm.
Viewed in the light most favorable to the verdict,[3] the evidence shows that the victim left his house to ask Jones, who was driving his loud car up and down the road at 11:30 p.m., to "calm it down a little bit." Jones responded that he was going to "kick [the victim's] ass," turned the car off, and put one leg out the door. The victim pinned the car door up against Jones, trapping Jones in place, and he told his girlfriend to call 911. According to the victim, Jones repeatedly threatened to kill him as they waited for the police to arrive. According to Jones, the victim pulled a knife out and put it to Jones's throat.
Several weeks later, the victim, who was pushing his child's stroller down the street, recognized Jones's car. When the car stopped, Jones exited the passenger's side of the car and yelled, "I told you I'm going to kill you." Jones unsheathed a six- to eight-inch long knife. While the victim's friend "grabbed the baby," the victim began backing *361 away from Jones, who ran up and began stabbing him in the side. As a result of his injuries, the victim lost his spleen, suffered a collapsed lung, and spent six days in the intensive care unit.
1. Jones claims that the trial court erred in excluding evidence of threats of violence made by the victim to Jones and his family. We disagree.
Jones's sister testified that the victim rented a house from her mother. The State objected to the sister's subsequent testimony that the victim was "upset with me and my mother and he threatened to kill us" as irrelevant, and the trial court sustained the objection. The trial court then asked to hear a proffer of Jones's niece's testimony in order to not "let the same thing happen with this witness." According to the niece, the victim threatened her, Jones's sister, and the mother on several occasions when the victim was behind on his rent, informing them "that we needed to get off his property or he was going to get his gun," and that "I will kill [Jones] because I want to get back at you." The niece admitted, however, that she did not relay this information to Jones. The trial court sustained the State's objection to the niece's testimony.
As a rule, "[t]he general character of the parties and especially their conduct in other transactions are irrelevant matter unless the nature of the action involves such character and renders necessary or proper the investigation of such conduct."[4] Thus, "[t]he victim's previous difficulties are rarely relevant for any purpose in a criminal proceeding.... An exception does exist when the defendant claims justification for his actions and offers evidence that the victim was the aggressor."[5]
Jones contends that the evidence of threats of violence by the victim against Jones and his family was relevant to support a defense of self and others. Although Jones contends that the victim's threats were "inferentially communicated," the evidence did not show that the threats were communicated by the sister or niece to Jones. Jones also argues that if the jury had heard all of the evidence, Jones's testimony could have been corroborated and therefore believed by the jury. "Where there is a conflict in the evidence as to who is the aggressor, evidence of threats previously made but uncommunicated to the defendant [is] admissible to corroborate evidence of threats which were in fact communicated."[6] The evidence, however, showed only that Jones was the aggressor in the incident in which the victim was stabbed, and so a foundation was not laid for the admission of the uncommunicated threats.[7] The trial court did not err in sustaining the State's objections.
2. Jones claims that the trial court erred in failing to charge the jury on his sole defense of justification, including principles of defense of self and others, misapprehension of fact, and no duty to retreat. We disagree.
"When the evidence could support a charge on the defendant's sole defense, such charge must be given by the trial court whether or not requested by the defendant."[8] "A person is justified in threatening *362 or using force against another when and to the extent that he or she reasonably believes that such threat or force is necessary to defend himself or herself or a third person against such other's imminent use of unlawful force...."[9]
Jones testified that the victim "shot me a bird and laughed" while Jones and his wife were on the way to the store, and that "when we come back, he had come down the road, I told my wife to stop and I got out of the car and I stabbed him." When defense counsel asked Jones if the victim did "anything to you before you stabbed him, or how did that go down," Jones responded "No, it was just the incident where he had broke my leg and tried to cut my throat...." Although Jones complained that the victim dug his finger into his eye, he confirmed that this occurred after he had stabbed the victim. In view of Jones's own testimony, when he assaulted the victim he could not have reasonably believed that either he or a third party required defense from the victim's imminent use of unlawful force. Even if, as Jones argues, he had reason to believe that the victim was armed with a knife, the victim, who was on foot pushing a stroller, was not an immediate threat to Jones or his wife as they drove by in their car. "Including reasonable inferences, there was no evidence whatsoever on which a finding of the justification of self-defense ... could be based."[10] Accordingly, the trial court did not err in failing to charge the jury on self-defense.
Nor did the trial court err in failing to instruct the jury on the principle of duty to retreat or misapprehension of fact. "The rule in Georgia is that if the person claiming self-defense was not the original aggressor there is no duty to retreat."[11] The evidence shows, however, that Jones was the aggressor, and we disagree with Jones that the State put retreat into issue by asking Jones questions on cross-examination that tended to highlight the fact that Jones approached the victim.[12] Nor, as Jones contends, does the evidence that the victim "was known by [Jones's] family to carry a knife," demonstrate that Jones "was induced by a misapprehension of fact which, if true, would have justified the act or omission."[13] Even if Jones was mistaken about the victim possessing a knife, the misapprehension, if true, would not have justified his actions.[14]
3. Jones filed a new appellate brief on February 25, 2010, incorporating the claims of error from the original brief, filed September 16, 2009, but adding a claim of ineffective assistance of trial counsel. "Attempts in a supplemental brief to expand the issues beyond the scope of the [original] enumeration of errors are improper."[15] Accordingly, we do not consider the issue.
Judgment affirmed.
