STATE of North Carolina
v.
Jeffery Dale SPICER.
No. 8023SC596.
Court of Appeals of North Carolina.

*523 Atty. Gen. Rufus L. Edmisten by Sp. Deputy Atty. Gen. John R. B. Matthis and Asst. Atty. Gen. Alan S. Hirsch, Raleigh, for the State.

William C. Gray, Jr., Wilkesboro, for defendant Jeffery Dale Spicer.
WELLS, Judge.
Defendants' first assignment of error focuses on several instances during trial when *524 the trial judge either questioned witnesses about their testimony or commented about testimony. Defendants contend that by this action, the trial judge erroneously expressed an opinion in the presence of the jury. We have carefully examined the record with respect to this assignment and find no prejudicial conduct on the part of the trial judge.
Defendants next make several assignments of error based upon an offer of charge reduction made by the district attorney to Henry A. Minton for the purpose of securing Minton's truthful testimony against defendants in the case sub judice. Defendants first contend that the trial court erred in not requiring the district attorney to comply with G.S. 15A-1054 which authorizes charge reductions in exchange for truthful testimony but provides:
(c) When a prosecutor enters into any arrangement authorized by this section, written notice fully disclosing the terms of the arrangement must be provided to defense counsel, or to the defendant if not represented by counsel, against whom such testimony is to be offered, a reasonable time prior to any proceeding in which the person with whom the arrangement is made is expected to testify. Upon motion of the defendant or his counsel on grounds of surprise or for other good cause or when the interests of justice require, the court must grant a recess.
From the record it appears that defense counsel was first apprised of the offer at a bench conference out of the hearing of the jury during the examination of Henry Minton at trial. At that time the district attorney explained that Minton had eleven felony indictments pending, and that in return for Minton's truthful testimony against defendants, the district attorney had offered to let Minton plead guilty to misdemeanors in the eleven charges and not to schedule the cases for trial until Minton's current probation was terminated. Defendants contend that G.S. 15A-1054 was violated because defendants did not receive written notice of this offer. We agree.
The State contends that there was no agreement and that therefore the statute did not apply. Although the district attorney stated that there was no agreement and although at one point in his testimony, Henry Minton stated "I ain't made no deal", the plea bargain may still be enforceable if the offer induced Minton's testimony. See Note, Enforcement of Plea Bargaining Agreements, 51 N.C.L.Rev. 602, 609 (1973). Promises by prosecutors of assistance or leniency, even if tentative, might be interpreted by a witness as contingent upon the nature of his testimony. See Campbell v. Reed, 594 F.2d 4, 7 (4th Cir. 1979); State v. Edwards, 37 N.C.App. 47, 48-19, 245 S.E.2d 527, 528 (1978). Although Minton denied that a deal had been made, he nevertheless testified that he expected the district attorney to drop the felony charges to misdemeanors if Minton pled guilty to them. Minton's credibility as a witness was an important issue in the prosecution of defendants and evidence of any understanding or agreement with the district attorney for leniency was relevant to Minton's credibility. See Campbell v. Reed, supra.
Although the district attorney should have complied with G.S. 15A-1054(c), such non-compliance does not require suppression of Minton's testimony. State v. Lester, 294 N.C. 220, 229, 240 S.E.2d 391, 398-99 (1978); State v. Edwards, supra. The defendants' remedy for failure to comply with the statute was to move for a recess. G.S. 15A-1054(c). In this case, defendants did not request a recess and did not except on the basis of failure to grant a recess. Defendants have not shown any prejudice by the lack of the required notice, and this assignment is overruled. State v. Lester, supra.
Defendants also assign error to the failure of the trial judge to inform the jury of the full extent of the understanding between the district attorney and Henry Minton, to the trial judge's refusal to allow all of defendant counsels' questions when cross examining Minton about the offer of leniency, and to the trial judge's failure to *525 adequately instruct the jury about the purported deal. We disagree and hold that the jury was fully informed of the possible agreement between the district attorney and Minton prior to the time it began deliberations. See State v. Cousins, 289 N.C. 540, 545, 223 S.E.2d 338, 342 (1976). Counsel for defendants cross examined Minton extensively on the specific crimes charged under the indictments and on "the kind of deal" Minton had with the district attorney. After questioning Minton about the crimes charged, defense counsel would inquire, "What kind of deal do you have with the prosecutor in return for your testimony here today as to that?" Minton's repeated response was "I told you I could plead guilty to a misdemeanor." In view of the lengthy and repetitious cross examination of Minton on this issue, we cannot say that the trial judge erred in sustaining objections to three of the approximately forty questions that defense counsel propounded. See State v. Abernathy, 295 N.C. 147, 151-52, 244 S.E.2d 373, 377 (1978); State v. McPherson, 276 N.C. 482, 487, 172 S.E.2d 50, 53-54 (1970). In holding that the jury was adequately informed of the possible agreement of charge reduction, we note that the trial judge charged the jury in part:
[T]he Court charges you that as to any arrangements that were made, if any were made, and there is some evidence that the witness, Henry Allen Minton, was testifying under some understanding for a charge reduction in return for his testimony in these cases. If you find that Henry Minton testified in whole or in part for this reason, you should examine his testimony with great care and caution in deciding whether or not to believe it.
Each of defendants' assignments of error regarding Minton's possible agreement with the district attorney is overruled.
Defendants next assignment of error relates to the following exchange in the record, when Kyle Gentry, the sheriff who investigated the shootings, was testifying:
CROSS EXAMINATION by Mr. Gray [counsel for defendant Jeff Spicer]:
[Gentry:] I have known Mr. Minton for three or four years. Yes, sir, since before I was elected Sheriff.
Q. And, Sheriff Gentry, would it be a fair statement that you believe very little of what Henry Minton says?
MR. ASHBURN [District Attorney]: OBJECTION.
COURT: OBJECTION SUSTAINED.
Q. Sheriff, what's the general reputation of Henry Minton as to his truth and honesty?
MR. ASHBURN: OBJECTION unless he can say he knows it.
COURT: Well, yes.
MR. FERREE: Cross examination.
COURT: Well, one thing you're limiting it to a specific person, if he knows his general character and reputation he can say so. If he wants to elaborate he may say so. That's fundamental. OBJECTION SUSTAINED.
Q. Sheriff Gentry, do you know the general reputation and character of Henry Minton here in the community in which he lives?
A. Yes, I do.
Q. And what is that?
A. It's not good.
Q. No further questions.
Defendants assign as error the trial court's refusal to allow defense counsel to cross examine Gentry about Henry Minton's general reputation for truth and veracity. This contention has no merit. The established rule allows only two questions to be asked of an impeaching character witness: (1) whether he knows the general reputation and character of the party, and (2) what that general reputation or character is. The witness may amplify or qualify his answers to the latter question with regard to specific virtues or vices of the party but counsel offering the witness may not suggest that the witness do so. State v. Abernathy, supra, at 166-67, 244 S.E.2d at 385-86; State v. Hairston, 121 N.C. 579, 28 S.E. 492 (1897). The trial judge's rulings with regard to this issue were proper.
*526 Defendants next assignment of error regards the State's cross examination of one of defendants' witnesses, Ted Porter, the half-brother of defendants who testified as to the defendants whereabouts prior to 4:00 a.m. on 22 July 1979. The district attorney asked Porter how many shotguns and rifles Porter owned. Defense counsel's objection was overruled. Porter answered that he owned two shotguns and three rifles. Defendants contend that such evidence was immaterial and had the sole effect of exciting the prejudice of the jurors. The admission of irrelevant evidence is ordinarily considered harmless error and the burden is upon appellant to show that he was prejudiced. State v. Atkinson, 298 N.C. 673, 683, 259 S.E.2d 858, 864 (1979). Although we agree that the disputed evidence was not relevant, defendants have not carried their burden of showing a reasonable possibility that had it not been for this irrelevant evidence's admission, a different result would have ensued. State v. Atkinson, supra, at 684, 259 S.E.2d at 865; G.S. 15A-1443(a). This assignment of error is overruled.
Defendants' next three assignments of error concern the admission as experimental evidence of a lighting experiment. On 31 July 1979 at approximately 4:00 a.m., Henry Minton, Kyle Gentry and two other persons, stood in the front yard of Minton's house with the various carport lights and floodlights attached to the front of the house illuminated. Steve Cabe, a special agent of the North Carolina State Bureau of Investigation, drove by in a pick-up truck. Pictures were taken. At the voir dire examination regarding the experiment there was testimony that the weather conditions on the nights of 22 July and 31 July were very similar, and that the houselights had not been altered between the two dates. Defendants presented evidence tending to show that the weather was foggy on the night of 22 July but clear on the night of 31 July. Subsequent to the voir dire examination, the trial judge found specific facts regarding the weather on the two dates and that the conditions existing when the experiment was performed were substantially the same as on the date at issue so that proper evidence with regard to the experiment could be introduced.
Defendants contend the trial judge committed error as follows: (a) in allowing before the jury the lighting experiment; (b) in failing to make proper findings at the conclusion of the voir dire examination, and (c) in failing to strike the experiment. The trial court is allowed a broad latitude of discretion in the admission of experimental evidence, especially with reference to the similarity of conditions existing at the time of the crime and conditions at the time of the experiment. See State v. Carter, 282 N.C. 297, 300, 192 S.E.2d 279, 281 (1972). We hold that in this case the trial judge did not abuse his discretion in his rulings concerning the experiment. See State v. Jones, 287 N.C. 84, 98-99, 214 S.E.2d 24, 34-35 (1975). The evidence offered on voir dire supported the trial judge's findings of fact, and in our opinion the trial judge was not "too wide of the mark" in determining that the conditions during the experiment were substantially similar to those surrounding the alleged homicide. State v. Jones, supra, at 99, 214 S.E.2d at 34. Defendants' three assignments of error concerning this experiment are overruled.
Defendants next assign error to the trial judge's denial of defendants' motions for judgment as of nonsuit. Defendants contend that there was not sufficient evidence of each essential element of the offense of second degree murder or that defendants had committed that offense. In considering defendants' motions, the evidence must be considered in the light most favorable to the State and the State must be given the benefit of every reasonable inference to be drawn therefrom. State v. Clark, 300 N.C. 116, 125, 265 S.E.2d 204, 210 (1980). If there is direct or circumstantial evidence, or a combination of both, from which the jury could find that defendants committed the offense charged, the motion for judgment as of nonsuit must be denied. State v. Jones, supra, at 101, 214 S.E.2d at *527 36. Murder in the second degree is the unlawful killing of a human being with malice but without premeditation and deliberation. State v. Wilkerson, 295 N.C. 559, 577, 247 S.E.2d 905, 915 (1978); State v. Wrenn, 279 N.C. 676, 681, 185 S.E.2d 129, 132 (1971). The intentional use of a deadly weapon as a weapon, when death proximately results from such use, gives rise to the presumptions that (1) the killing was unlawful, and (2) done with malice. State v. Duboise, 279 N.C. 73, 81, 181 S.E.2d 393, 398 (1971). See also State v. Wrenn, supra. Here, all the evidence tends to show that the defendants were engaged in a deliberate course of conduct which included the intentional firing of a gun a number of times in the direction of the deceased girl, the bullets from such shots hitting her and another person. Such evidence was clearly sufficient to overcome defendants' motions of nonsuit and to justify the jury's verdict of guilty of second degree murder. This assignment is without merit and is overruled.
Defendants' final assignment of error concerns the failure of the trial judge to instruct the jury on the lesser included offense of voluntary manslaughter. When there has been some evidence presented of defendant's guilt of a lesser included offense, defendant is entitled to have the question submitted to the jury even if there was no specific prayer for such instruction. State v. Bell, 284 N.C. 416, 419, 200 S.E.2d 601, 603 (1973). Voluntary manslaughter is the unlawful killing of a human being without malice, and without premeditation or deliberation. State v. Wilkerson, supra, at 577, 247 S.E.2d at 915, quoting with approval State v. Wrenn, supra, at 681, 185 S.E.2d at 132. A killing is without malice if the one who kills acted while under the influence of passion or in the heat of blood produced by adequate provocation. State v. Williams, 296 N.C. 693, 701, 252 S.E.2d 739, 744 (1979). Defendants contend that there was some evidence that defendant acted in the heat of passion caused by adequate provocation.
There was evidence in the record that there had been discord between the Minton and Spicer families prior to 22 July. The evidence also indicated that the defendants' mother arrived at Wilkes Hospital at about 1:30 or 2:00 on the morning of 22 July for treatment of a gunshot wound. Various friends and members of her family, including defendants, visited defendants' mother at the hospital in the early morning hours. The record also contained the testimony of Henry Minton's father who was inside the Minton house at the time of the crime at issue. Minton's father testified that at that time he heard shots being fired in front of the house.
Q. All right, what occurred then?
A. Joe, Jr. said, "Minton," said, "come on out here," said, "I'm going to blow your God-damn brains out," and he kept saying, "Open that door if you don't believe I'll blow your brains out," and he said that, uh, "If my mother dies, you better believe I will kill you."
Defendants assert that this testimony is evidence that defendants acted in the heat of passion.
Defendants' argument is grounded in the proposition that "heat of passion", i. e., rage, anger, hatred or furious resentment rendering the mind incapable of cool reflection, is sufficient to show lack of malice. Mere "heat of passion" is not enough. Such "heat of passion" must arise upon reasonable or adequate provocation, which in turn can only arise under circumstances amounting to an assault or a threatened assault. State v. Williams, supra, at 702, 252 S.E.2d at 745; State v. Watson, 287 N.C. 147, 156, 214 S.E.2d 85, 90-91 (1975); see also State v. Hamrick, 30 N.C.App. 143, 148, 226 S.E.2d 404, 407 (1976), disc. rev. denied, 290 N.C. 780, 229 S.E.2d 35 (1976). Here, while there is evidence that defendants' mother may have been assaulted, there is no evidence whatsoever as to who may have assaulted her. Furthermore, the evidence is clear that the events giving rise to defendants' mother's wounds were considerably removed in time from the events surrounding the death of Robin Darlene *528 Griffin. Accepting, arguendo, that an assault or threatened assault on a close relative may provide adequate or legal provocation to arouse heat of passion [1] the evidence here does not show "anger suddenly[2] aroused by provocation which the law deems adequate to dethrone reason temporarily and to displace malice." State v. Ward, 286 N.C. 304, 312, 210 S.E.2d 407, 413 (1974), modified, 428 U.S. 903, 96 S.Ct. 3206, 49 L.Ed.2d 1207 (1976). "The law extends its indulgence to a transport of passion justly excited and to acts done before reason has time to subdue it; the law does not indulge revenge or malice, no matter how great the injury or grave the insult which first gave it origin." State v. Ward, supra, at 313, 210 S.E.2d at 414. This assignment is without merit and is overruled.
Our examination of the entire record discloses that defendants received a fair trial, free from prejudicial error.
No error.
