SHEPHERD, J.

In these consolidated cases, defendants Derrick Harris, Alfreda Drake, and Cortez Walker appeal as of right their convictions and sentences. Defendants were originally charged with first-degree murder and assault with intent to commit murder as a result of their involvement in the February 4, 1988, beating death of Mary Guyton and assault of Ervin Brewer. Each of the defendants was convicted of second-degree murder, MCL 750.317; MSA 28.549. Walker was also convicted of assault with intent to commit murder, MCL 750.83; MSA 28.278. Harris was sentenced to 35 to 100 years' imprisonment, Drake was sentenced to life imprisonment, and Walker was sentenced to concurrent prison terms of 50 to 100 years and 80 to 120 months.

According to Ervin Brewer, Guyton and a man named Chico had been selling crack cocaine out of the apartment in which Guyton and Brewer were attacked. Defendants Harris and Drake first came at around 8:00 A.M. on February 4, 1988, to collect money for the crack, but Guyton did not have the full amount. Harris and Drake then left, but returned a short time later with a man named Quincy. Quincy threatened Guyton and Brewer that if he did not get his money by noon, they both would be killed. Quincy, Harris, and Drake then left the apartment again, returning shortly thereafter with defendant Walker and a rifle.

Quincy and defendants Harris and Drake began beating Guyton and continued to do so as she fled into the bedroom. Meanwhile, Chico and defendant Walker beat Brewer with the rifle, a lamp, and their fists and feet. Brewer heard defendant Drake say Guyton should be beaten with a skillet and he then saw one of the men get a skillet. Another witness saw Chico get a skillet and take it into the bedroom. He also heard Guyton call defendant Drake a "bitch," and then heard slapping noises. Brewer was eventually ordered into the bedroom, where he saw Guyton with her hands bound, bleeding and begging for her life. Brewer was then told to lay face down on the floor, whereupon his hands were tied behind his back with a telephone cord and he was kicked.

Quincy, Chico, and Walker continued to beat Guyton for about two hours, with Drake periodically joining in. At one point, Guyton was permitted to make two phone calls in an effort to get the money, but she was unsuccessful and the beating continued. As the two victims were being beaten, defendant Harris sprayed Guyton with soda pop. Brewer later recalled cold water being poured on him. Defendant Walker, Quincy, and Chico eventually put Guyton in a closet, where they continued to beat her. After the assailants were gone, Guyton did not respond to Brewer's calls. Brewer managed to free himself, and he fled the apartment through the bedroom window. The police found Guyton's body lying face down in the closet with her hands tied behind her back with wire and a telephone cord. An autopsy revealed multiple fresh bruises, lacerations, and abrasions on Guyton's face, scalp, neck, back, chest, hands, and arms. The coroner opined that death was caused by multiple blunt force trauma and compression of the neck.

DOCKET NO. 115243

As do the other defendants, defendant Harris raises a number of issues on appeal. The first is that there was insufficient evidence to support binding him over on the two charged offenses and that his motion to quash the information should have been granted. The function of the examining magistrate is to determine whether a crime has been committed and whether there is probable cause for charging the defendant with that crime. MCL 766.13; MSA 28.931; People v King, 412 Mich. 145, 152-153; 312 N.W.2d 629 (1981). A reviewing court may not substitute its judgment for that of the magistrate, but may reverse only upon a determination that the magistrate abused his discretion. People v Talley, 410 Mich. 378, 385; 301 N.W.2d 809 (1981).

We find no abuse of discretion here. With regard to the murder charge, the prosecution only needed to show some evidence that defendant either possessed the requisite intent to kill Guyton or participated knowing that the principals had such intent. See People v Youngblood, 165 Mich. App. 381, 387; 418 N.W.2d 472 (1988). Premeditation and deliberation could be inferred from the circumstances surrounding the killing and the apparent organized conduct before it, such as defendant's having repeatedly returned with more people and a weapon. Although Harris himself did not assault Brewer, the circumstances and events surrounding the crime gave rise to an inference of an organized plan in which defendant participated.

Defendant also challenges the trial court's denial of his motion for a directed verdict with respect to both charges. We review the denial of such a motion by reviewing the evidence presented in a light most favorable to the prosecution and determining whether a rational trier of fact could have found the essential elements of the charged offenses proven beyond a reasonable doubt. People v Hampton, 407 Mich. 354, 368; 285 N.W.2d 284 (1979), cert den 449 U.S. 885 (1980). Defendant's motion was properly denied with respect to both charges. Defendant was prosecuted under an aiding and abetting theory on the assault charge, and there was sufficient evidence to submit to the trier of fact the issues of the aid and encouragement given by defendant to Walker and Chico, who did the actual beating, as well as defendant's knowledge of their intent to murder Brewer. With regard to the murder charge, defendant claims that the testimony showed that he intended that Guyton remain alive and that he left the apartment and tried to get the others to leave while Guyton was still alive, thus negating the element of premeditation and deliberation. However, viewing the evidence in a light most favorable to the prosecution, we find that there was evidence that defendant orchestrated a plan to bring help and weapons to the apartment and that he participated in Guyton's beating and sprayed her with soda while others were beating her. There was sufficient evidence from which a jury could infer premeditation and deliberation.

Defendant further contends that his conviction for second-degree murder was against the great weight of the evidence and that his motion for a new trial therefore should have been granted. We review the denial of that motion for an abuse of discretion. An abuse of discretion will be found only where denial of the motion was manifestly against the clear weight of the evidence. People v Gonzalez, 178 Mich. App. 526, 532; 444 N.W.2d 228 (1989). We find no abuse of discretion here.

To establish second-degree murder, the prosecution was required to prove that defendant caused the death of the victim and that the killing was done with malice and without justification or excuse. People v Porter, 169 Mich. App. 190, 192; 425 N.W.2d 514 (1988). Malice is the intent to kill, the intent to do great bodily harm, or the intent to create a high risk of death or great bodily harm with knowledge that such is the probable result. Malice may be inferred from the facts and circumstances of the killing. Id., pp 192-193. The evidence in this matter revealed that Guyton died as a result of multiple blunt force trauma and compression of the neck, either one alone being sufficient to kill her. The police found two skillets with blood on them, and the medical examiner testified that the blunt force injuries could have been inflicted with the skillets. There was also testimony that defendant actively participated in Guyton's beating, at least up to a certain point, and thereafter sprayed her with soda while the others continued to beat her. This evidence showed that defendant participated in the beating or aided and encouraged others. Malice could be inferred from the number of people attacking Guyton, the duration of the beating, and the instruments used. There was no claim of excuse or justification.

Defendant further assigns error to the trial court's failure to grant a mistrial after his codefendant, Walker, apparently attacked the prosecutor with the jurors present. We have carefully reviewed the record and find that the trial court did not abuse its discretion in denying the motion. See People v Siler, 171 Mich. App. 246, 256; 429 N.W.2d 865 (1988). The inquiry in situations such as this focuses on the defendant's ability to get a fair trial. Id. The trial court admonished the jurors regarding their function and duties, and questioned each one individually to determine the effect, if any, of Walker's outburst on them. All the jurors indicated they could remain impartial, and those jurors who had expressed some concern at the time of the incident explained that they merely reacted to what was to them a frightening and unusual situation but that they understood the event could not be allowed to influence their decisions. Furthermore, contrary to defendant's assertion, there is no evidence any of the defendants were thereafter shackled. We believe the trial court went to great lengths to ensure that the defendants received a fair trial, and we perceive no prejudice to defendant that would warrant a finding that the court abused its discretion in denying defendant's motion for a mistrial.

Defendant's fifth contention is that he was denied a fair trial because of the prosecutor's conduct in questioning a witness. While we agree with defendant that on several occasions the prosecutor did not properly impeach the witness with a prior inconsistent statement, a foundation was initially laid for the statement and, given the difficult nature of this witness, who often refused to answer direct questions, we find no prejudice to defendant or that he was denied a fair trial by the questioning.

Defendant next argues that the trial court erred in failing to instruct the jury with regard to voluntary manslaughter as requested. We initially note that defendant's counsel did not object to the court's failure to include this instruction in the jury charge, thereby waiving appellate review unless there is a miscarriage of justice. People v Watkins, 178 Mich. App. 439, 450; 444 N.W.2d 201 (1989), lv gtd 435 Mich. 867 (1990). There was no miscarriage of justice here, because there was no evidence to support this lesser offense. See People v Beach, 429 Mich. 450, 476; 418 N.W.2d 861 (1988). A homicide may be reduced to voluntary manslaughter if the circumstances surrounding the killing show that malice was negated by adequate and reasonable provocation and the homicide was committed in the heat of passion. People v Townes, 391 Mich. 578, 589; 218 N.W.2d 136 (1974). The evidence adduced at trial did not support a finding of provocation or that defendant acted with a state of mind incapable of cool reflection, id., such that a jury could convict him of voluntary manslaughter.

Defendant Harris also argues that his sentence was excessive. Because defendant Walker raises the same argument and we reach the same result in both cases, we will comment on the sentences at the conclusion of this opinion.

DOCKET NO. 115739

Defendant Drake likewise appeals both her conviction and sentence. Her first contention is that she was denied a fair trial because she was denied the right to testify on her own behalf and there was no waiver of that right made on the record. We find no merit to this argument. In People v Simmons, 140 Mich. App. 681; 364 N.W.2d 783 (1985), this Court, aligning itself with the majority of jurisdictions, held that there is no requirement in Michigan that there be an on-the-record waiver of a defendant's right to testify. Defendant herein did not testify, and, contrary to her argument, the trial court had no duty to advise her of the right, nor was it required to determine whether she made a knowing and intelligent waiver of the right.

Defendant next contends that she was denied a fair trial because the jury apparently discussed the case after defendant Walker's outburst. We disagree. If the jurors discussed the case, the discussion focused on their responsibility to remain impartial, not on the facts of the case. Defendant has further failed to demonstrate any prejudice as a result of this alleged discussion and has thus failed to establish any basis for a new trial. See People v Rohrer, 174 Mich. App. 732, 739-740; 436 N.W.2d 743 (1989).

Defendant's third argument is that she is entitled to have the presentence report amended and a corrected copy sent to the Department of Corrections in light of the trial court's acknowledgment at sentencing that, contrary to what was stated in the report, defendant did have an employment history. We agree and remand for the report to be amended and a copy thereof sent to the Department of Corrections. MCL 771.14(5); MSA 28.1144(5); People v Norman, 148 Mich. App. 273; 384 N.W.2d 147 (1986).

Defendant Drake's final contention concerns the scoring of offense variables 6 (multiple victims) and 7 (exploitation of victim vulnerability) on the sentencing information report. She claims that these offense variables were improperly scored and that the trial court did not address her claims of inaccuracy. She further asserts that while the guidelines range would not have been affected, proper scoring of these offense variables would have placed her at the low end of level IV and, thus, may have affected her sentence. We find no basis for resentencing here, because there was evidence to support the scoring of both offense variables.

Defendant's sole objection to the scoring of offense variable 6 rests on the fact that she was acquitted of the assault charge stemming from the beating of Ervin Brewer. The question whether a sentencing court may consider criminal activity of which the defendant was acquitted was recently addressed by our Supreme Court in People v Ewing, 435 Mich. 443; 458 N.W.2d 880 (1990). Of the five justices who addressed the issue, four found that such conduct could be taken into account at sentencing because an acquittal does not necessarily mean that the defendant did not engage in criminal conduct, but only demonstrates a lack of proof beyond a reasonable doubt. See also People v Wiggins, 151 Mich. App. 622, 625; 390 N.W.2d 740 (1986).

Our review of sentencing guidelines calculations is very limited. People v Richardson, 162 Mich. App. 15, 16; 412 N.W.2d 227 (1987). A sentencing judge has discretion in determining the number of points to be scored, provided that there is evidence on the record which adequately supports a particular score. People v Day, 169 Mich. App. 516, 517; 426 N.W.2d 415 (1988). Where effectively challenged, a sentencing factor need be proved only by a preponderance of the evidence. People v Walker, 428 Mich. 261; 407 N.W.2d 367 (1987). While defendant Drake herself may not have physically attacked Brewer, the two beatings were inextricably woven together such that the court could find more than one victim was involved. We further find sufficient evidence to support the scoring of offense variable 7, because defendant Drake joined three men and one 300-pound teenager in an attack on a 5-foot-5-inch, 114-pound woman whose hands were bound behind her back, rendering her defenseless. The trial court did not abuse its discretion in scoring these offense variables as it did.

DOCKET NO. 116045

Defendant Walker raises six issues on appeal, the first of which is a claim that the trial court's instruction to the jury with regard to aiding and abetting was erroneous because it did not state that the principal and accomplice must have a shared mens rea and intend the commission of the same offense. We disagree.

Jury instructions must include all the elements of the charged offense and must not exclude material issues, defenses, and theories if there is evidence to support them. People v Reed, 393 Mich. 342, 349-350; 224 N.W.2d 867 (1975), cert den 422 U.S. 1044 (1975). Jury instructions are reviewed in their entirety to determine if error requiring reversal occurred, and they are not extracted piecemeal in an effort to establish error. People v Burgess, 153 Mich. App. 715, 726; 396 N.W.2d 814 (1986). Even though the instructions may be somewhat imperfect, there is no error if they fairly presented to the jury the issues to be tried and sufficiently protected the rights of the defendant. People v Kalder, 284 Mich. 235, 241-242; 279 N.W. 493 (1938). No error results from the omission of an instruction if the charge as a whole covers the substance of the omitted instruction. People v Bender, 124 Mich. App. 571, 575; 335 N.W.2d 85 (1983). The trial court's instructions in the present matter fairly presented the issues to be tried, including those issues for which defendant claims instructions were omitted, and sufficiently protected defendant's rights.

Defendant argues that the trial court erred in failing to instruct the jury regarding voluntary manslaughter. There was no evidence adduced at trial to support such an instruction, and we therefore find this argument to be without merit.

Defendant's third claim is the same as defendant Harris' contention regarding the prosecutor's questioning of a witness. We need not revisit the issue.

Defendant Walker also argues that the trial court erred in failing to resolve a claimed inaccuracy in the presentence report regarding defendant's having gained a portion of his financial support through narcotics distribution and that he should therefore be resentenced or the matter remanded for a hearing regarding the challenged information. We find, however, that the trial court accepted defendant's refutation of the challenged information. Although the court later took into consideration the fact that the murder and assault were connected to drug activity, this acknowledgment was not contrary to the court's acceptance of defendant's challenge to the disputed information. The fact that defendant Walker did not gain a portion of his income from narcotics distribution, if it could be proven, would not alter the fact that Guyton's murder stemmed from her failure to fully pay her drug supplier.

SENTENCES OF HARRIS, DOCKET NO. 115243, AND WALKER, DOCKET NO. 116045

Harris was sentenced to 420 to 1200 months, i.e., 35 to 100 years. Walker received a sentence of 50 to 100 years for the murder charge and 80 to 120 months for the assault conviction. The guidelines range for Harris was 120 to 300 months or life, and the guidelines range for Walker was 144 to 300 months or life. Thus, Harris received a minimum sentence that was ten years greater than the guidelines' recommendation, and Walker's minimum sentence exceeded the guidelines' range by twenty-five years. Because we are required to review these sentences under People v Milbourn, 435 Mich. 630; 461 N.W.2d 1 (1990), our question must be whether the record adequately demonstrates that the sentences meet the standard of proportionality announced in that case. Our response is that the trial judge did not have the benefit of Milbourn when these sentences were imposed and we are unable to tell from the record what the sentences might have been had the trial judge employed the Milbourn standard. We therefore remand for resentencing.

The crimes in these cases were exceptionally violent, and there would be, in our view, some justification for imposing a sentence at or beyond the outer limit of the guidelines' range. Milbourn reestablishes the doctrine that a sentence within the guidelines is presumptively valid. Had the sentences been within the guidelines, we would have found no reason to question them.

The guidelines are a reflection of the sentences that courts actually impose for various offenses and offenders. Contrary to popular belief that exists in some quarters, a sentence within the guidelines, particularly at the outer limits of the guidelines, is not a mere slap on the wrist. The guidelines, attempt to take into account all the factors that a trial court is required to consider, including the seriousness of the offense and the prior record of the offender. In the instant cases, the trial judge exceeded the guidelines by ten and twenty-five years and justified the departure with factors that already may have been taken into account in the guidelines.

Certainly, every case is unique, but one purpose of the guidelines is to avoid turning each unique feature of a case into a separate category. Normally, if the unique facts of the case fit into a guidelines category, then the unique facts have been taken into account by the guidelines. For example, in the case of Harris, he sprayed soda pop on the dying victim. The guidelines did not make and could not have made a separate category for that act. However, such callousness fits into the category of "aggravated physical abuse," a category that is covered by the guidelines. Michigan Sentencing Guidelines (2d ed), p 77.

This illustrates why Milbourn held:

Where there is a departure from the sentencing guidelines, an appellate court's first inquiry should be whether the case involves circumstances that are not adequately embodied within the variables used to score the guidelines. A departure from the recommended range in the absence of factors not adequately reflected in the guidelines should alert the appellate court to the possibility that the trial court has violated the principle of proportionality and thus abused its sentencing discretion. Even where some departure appears to be appropriate, the extent of the departure (rather than the fact of the departure itself) may embody a violation of the principle of proportionality. See People v McKinley, 168 Mich. App. 496, 512; 425 N.W.2d 460 (1988). ("We do not dispute that a prison sentence — even a lengthy one — is in order. We conclude, however, that a fifteen-year minimum sentence for the events that occurred here is disproportionate to the specific acts committed and the danger involved. Too frequently reasons are given for a sentence that apply equally to a lesser or greater sentence unless an explanation is offered on the record for the specific sentence given. Such was the case here.") (Emphasis added.) [ 435 Mich. 659-660.]

In sum, we remand for resentencing because the record does not demonstrate that the sentences were proportional under Milbourn and because neither the necessity for a departure from the guidelines nor the magnitude of the departure has been subjected by a trial judge to the Milbourn proportionality test. This remand should not be interpreted as a criticism of the trial judge. He may not be criticized for failing to utilize a standard that did not exist at the time of sentencing. Nevertheless, the Supreme Court in Milbourn gave the proportionality test limited retroactivity and the Milbourn standard now applies to this case.

We do not wish to imply that the same sentences may not be imposed after the trial judge has had an opportunity to reflect on Milbourn and to have the benefit of arguments from counsel regarding how the doctrine of proportionality applies to this case. Our ruling is based solely on our inability to give meaningful appellate review under Milbourn, given the present state of the record.

On remand, there should be a threefold inquiry, at each stage of which the Milbourn proportionality test must be applied:

1. If the sentence is to be within the guidelines, where on the guidelines range should the sentence fall?

2. What unique facts exist that are not already adequately reflected in the guidelines, and why do such facts justify any departure from the guidelines?

3. If there is to be a departure, what should be its magnitude and the justification for the specific departure imposed?

We believe that the above lines of inquiry are what the Milbourn analysis requires. Milbourn by its very language does not seek to take away the judicial discretion of the trial judge. Rather, the opinion at page 662 et seq. demonstrates that it seeks to guide the exercise of that discretion along more rational and systematic lines. Judicial discretion must be something more than a hunch or a wild guess. The inquiry that we impose here will enable the trial judge to comply with the mandate of Milbourn in a manner that reduces the risk of irrational sentencing that is either too low or too high for the given case.

We do not hold that the above three-step analysis must be followed to the letter in every case. However, all of the factors mentioned in the analysis are contained in Milbourn and must, in some manner, be included in the trial judge's articulation on the record of the reasons for the sentence.

We affirm the convictions of all three defendants, remand Drake's case for the trial court to revise defendant Drake's presentence report and forward a corrected copy to the Department of Corrections, and remand in the Harris and Walker cases for resentencing consistent with this opinion and Milbourn.
