Lead Opinion
Irrelevant deoxyribonucleic acid (DNA) statistics and improper appeals to juror emotions by the prosecutor needlessly complicated the convictions of the defendant, Michael Grinkley, for indecent assault and battery on a child. Nonetheless, overwhelming evidence of guilt — the defendant was found in bed with his pants down, on top of one young victim and beside the other — and a discerning jury, who acquitted the defendant on rape and other charges, rendered the errors harmless. We therefore affirm.
This case arises from several incidents of sexual assault in
1. Background. On February 10 or 11, 2003, the older victim, then eight years of age, and her sister, the younger victim, then six years of age, were being cared for by their aunt Natalie at home in the Dorchester section of Boston.
At some point thereafter, the defendant went downstairs into the room where the children were sleeping together in the same bed. The older victim testified that the defendant climbed on the
The younger victim, who was lying on her stomach, testified that the defendant lay on top of her. The defendant put his “private” through the rip in her pajama pants onto her “private.” She then felt something wet and slimy “inside [her] private.” She described something “hard” “going against [her] legs.” The younger victim also asserted that the defendant touched both her sister and her “in a place that we don’t want to be touched in.”
Fifteen to twenty minutes later, several of the adults realized that the defendant was not with them in his apartment and went downstairs to look for him. They opened the door to the girls’ darkened bedroom and found the defendant, still on top of the younger victim.
His casual remarks, along with the compromising situation in which he was found, caused several of the family members to kick, punch, and nearly stab the defendant with a hastily grabbed knife while removing him from the bedroom.
After the defendant had been separated from the girls and taken to another room, Natalie spoke with each child individually.
Both girls testified that the defendant had inappropriately touched each of them on a prior occasion. At trial, the older victim testified that at some point in the past she, her younger sister, and their brother were watching a movie in the defendant’s apartment when the defendant licked her vagina. She could not remember if her clothes were on or off. She also testified that on the same occasion, the defendant “got [her] hand and made [her] touch his penis.” He was wearing clothes at the time. The incident was interrupted when their grandmother said there was a telephone call for the defendant.
The younger victim similarly testified to an occurrence in the defendant’s apartment on the third floor where the defendant looked at pornographic magazines (described by the girl as “magazines with nasty things in it”) with all three children. He then made the girls pull down their pants and get in his bed, where he proceeded to lick their “private spot.” The younger victim stated that he then pulled the covers over them, made his private spot touch hers, and moved up and down repeatedly. Additional facts regarding the assaults and the follow-up investigation will be set forth as necessary to address the particular legal issues raised.
2. DNA evidence. On the night of the February 10 or 11, 2003, incident, a number of biological samples were taken from the victims as part of the sexual assault kit examination. No semen was found in any of the testing. The samples, which contained amylase, an enzyme contained in biological fluids such as saliva, were submitted to the laboratory for DNA extraction, amplification, and analysis in accordance with its applicable protocols. The laboratory performed polymerase chain reaction (PCR) testing and produced a profile of the DNA found, in the samples. At the time, the laboratory examined sixteen different loci on the DNA molecules found in the samples to compile the DNA profile or profiles present in each sample. By means of comparisons to reference DNA samples of the victims and the defendant, the laboratory attempted to determine whether the particular known
Of the samples tested in this case, one ■— the perianal swab from the older victim — showed results indicating the presence of DNA not belonging to the victim in addition to the victim’s own DNA and thus was the only sample of any possible relevance in linking the defendant to the crimes charged via a DNA match.
None of the testing methodology so far described is at issue on appeal. At trial, however, the Commonwealth’s expert witness, Julie Lynch, testified to a statistic purporting to represent the proportion of different racial populations that could be possible contributors of their entire DNA to the profile identified in the perianal sample. Despite the defendant’s repeated pretrial and trial objections and requests for a Daubert-Lanigan hearing see Daubert v. Merrell Dow Pharmaceuticals, Inc.,
3. Admissibility of the DNA evidence and statistics. As explained above, the DNA evidence here was for a mixed sample. The victim was apparently the primary contributor, and the defendant was found to be a possible contributor in each of the five loci where DNA from an additional contributor was detected. The question we confront is what type of statistical evidence is appropriate in this context.
The product rule computes the probability (also called a frequency profile) that the DNA found in a given biological sample matches a randomly selected individual in the general population.
The prosecutor argued to the judge at trial that the statistical evidence here was justified by Commonwealth v. McNickles,
In Commonwealth v. McNickles,
In sum, the statistics offered were not authorized by Commonwealth v. McNickles, supra, or the other DNA cases. Rather, the statistics were meaningless and improper. The jury would, however, have wondered why they were being presented. The prosecutor appeared to be arguing that the expert’s testimony was that the “genetic profile [of] what is in the perianal evidence is . . . very, very, very rare . . . [and] is highly inculpatory,” because the chances for “someone else to have contributed the DNA ... are one in a cabillion.” Essentially, the prosecutor seemed to be contending that, because the DNA profile of the perianal sample was exceptionally rare, and the defendant met part of the profile, it was highly likely that the DNA was the defendant’s. This was of course inaccurate and misleading. The DNA profile reflected a mixed sample, not one person’s. The likelihood that the defendant contributed to the mixed sample analyzed was not in any way calculated. The judge therefore abused her discretion in allowing the Commonwealth to offer statistics based on a product rule calculation over the repeated objection of the defendant. The question then becomes whether the error was harmless.
Given the overwhelming evidence of the sexual assaults and the defendant’s acquittal on the rape charges, we conclude that the defendant was not prejudiced by the Commonwealth’s improper use of the product rule statistics.
We begin with the prosecutor’s suggestion that “a mixture of DNA [was] found in [the older victim’s] perianal area . . . [and only] [o]ne in three hundred and twenty billion [have that DNA].” As explained above, the statistical evidence was irrelevant and potentially misleading. Defense counsel’s objection was, however, sustained. Furthermore, defense counsel herself had made a similarly misleading reference to the statistics in her closing, arguing “whoever contributed to that swab . . . was one in a billion, billion,” and that person was not the defendant. The proper response by the prosecutor, however, should have been to object to the defendant’s abuse of the statistics or to answer and correct the prejudicial irrelevancy, not combat it with further misleading information. See Commonwealth v. Kozec, 399 Mass.
Regardless, as explained above, it is not clear what significance the reference to the DNA statistics in the closing argument has on appeal. The defendant was acquitted on the rape charges, which the DNA evidence was offered to prove. There was overwhelming evidence of sexual assaults, so we cannot discern the value, if any, the DNA evidence added in terms of proving sexual assault. We therefore deem the prosecutor’s reference to the figure in closing harmless.
Overreaching by the prosecutor, both on her own initiative and in response to defense tactics, was not, however, confined to the DNA evidence. In Commonwealth v. Deloney,
We recognize that the line between improper appeals to juror emotions and proper explanations of difficulties witnesses may have had in testifying is not always clear, particularly with regard to young children in sexual assault cases. The younger child in this case did in fact have difficulty recounting the details of the incidents, requiring her to write down what happened to her. In isolation, the prosecutor’s comments would be less troubling. In context, they are part of a coherent rhetorical appeal to juror emotions.
The prosecutor also stated: “Think about what it must have
Continuing in the same vein, the prosecutor responded inappropriately to an implausible argument by the defense that the victims’ statements were motivated by the rape examination. In elaborating on her argument that the victims’ statements were all a product of the suggestibility of children exposed to the hysterical reactions of the adults that night, defense counsel stated: “Well the suggestibility to the children did not end there. They were whisked in the middle of the night in an ambulance to the hospital where the two girls underwent a horrific physical exam. What child would think nothing had happened to them but yet they had to go through that exam? And we heard how painful it was. [The older victim] had to be given a sedative.”
In response, the prosecutor argued: “[A]sk yourself what possible motive do those girls have to come into this courtroom? Why? So that eight or so hours after they tell their aunt what happened they get to have a rape kit done? That’s the motive? And think about what [emergency room nurse] Dianne Courtney said that involves. Swabbing of the vagina, the anus, the perianal area. They were six and eight years old when they laid there in the frog position in the emergency room that night.”
There was no reason for either the prosecution or the defense to discuss or dwell on the pain and difficulty of the rape examination. Obviously the rape examination was the product of the sexual assault claim, not vice versa. Therefore, whatever con
In sum, the overwrought and inflammatory closing argument of the assistant district attorney, which ignored a prior warning from this court about many of the same unacceptable points of argument, was prosecutorial error. In examining the total effect of the different emotional appeals, we begin with the recognition that the defendant made a timely objection that the “whole closing was an appeal to sympathy. What it must have felt like, what it was like for her.” The judge denied a motion for a mistrial and gave no specific curative instructions. The judge did give standard instructions to the effect that arguments are not evidence, that the jury’s “verdict must be based solely on the evidence,” and that it “would be improper for [the jury] to consider any personal feelings or bias or prejudice or sympathy in deciding whether [they] should return a verdict of guilty or not guilty.”
We must determine whether these improper appeals to emotions, in these circumstances, possibly made a difference in the jury’s conclusions. In the instant case there was overwhelming evidence of sexual assaults — particularly on the night of February 10 or 11 when the defendant was found in bed with the two victims, on top of one of them, with his pants unzipped and her bare bottom exposed — and a close question whether there was penetration. The jury, apparently able to distinguish between, on one hand, argument and evidence and, on the other, excessive contentions by both parties, convicted the defendant on the
In sum, the verdict was reflective of the jury’s discernment and deeply rooted in the evidence, and it need not be overturned due to prosecutorial errors. Nonetheless, we are again left “to wonder why some prosecutors persist, by ill advised rhetoric and inflammatory remarks, in attempting to snatch defeat from the jaws of victory.” Commonwealth v. Jones, 9 Mass. App. Ct. 103, 119 (1980), S.C.,
Judgments affirmed.
Notes
The Commonwealth filed nolle prosequis as to the other four indictments charging indecent assault and battery of a child under fourteen.

The actual level of light in the room at the relevant time was disputed at trial.
The court in Commonwealth v. Vao Sok,
“The genetic and molecular basis of DNA typing is described in the appendix to the [Supreme Judicial Court’s] decision in Commonwealth v. Curnin,409 Mass. 218 , 227-231 (1991). There, the [Supreme Judicial Court] pointed out that forensic DNA testing is directed at the examination and comparison of the characteristics of several ‘highly polymorphic alleles.’ The Cumin case described the meaning of the scientific term ‘highly polymorphic alleles’ as follows:
“ ‘A single DNA molecule contains approximately three billion rungs, or base pairs. Certain types of human genes . . . can occur in alternate forms (that is, with differing sequences of base pairs), each of which is capable of occupying a gene’s position on the DNA ladder. These alternate forms of genes are called “alleles,” and are highly variable from one person to another. Alleles of a particular gene contain a different number of base pairs, and therefore are of different lengths.’
“ ‘Most of the sequences of base pairs in all human DNA molecules are identical. However, roughly three million base pairs are alleles that vary in sequence among humans. The areas on the DNA ladder in which the DNA sequence varies are called “polymorphic sites.” Some such sites are more polymorphic than others. Forensic DNA testing makes use of sites which are “highly polymorphic.” ’ Cur-nin, supra at 228.
“The variations or polymorphisms between alleles at a particular location may occur either in the particular sequence of the base pairs at a particular locus or in the length of a DNA fragment between two defined endpoints. It is the ability to detect and compare the alleles at a particular locus in one sample of DNA with the alleles at that same locus in another sample of DNA that forms the basis for the use of the technology in a forensic setting.”
The other samples resulted only in matches for the respective victims’ own DNA profiles.
In order to be included as a contributor of the additional DNA in the sample, all of the defendant’s DNA characteristics would need to have been identified.
We note that the chart included in the defendant’s brief, based on evidence admitted at trial, appears to show thirteen alleles of the defendant not found in the sample. This discrepancy does not affect our analysis.
A distinction between primary and secondary contributors can be drawn when two individuals contribute to a DNA mixture in unequal amounts. Readings produced by the larger sample show as darker in the PCR-testing results than those in the smaller sample. See Commonwealth v. Gaynor,
The defendant is African-American.
An issue not presented in this case, but which is presently before the Supreme Judicial Court, is whether DNA evidence of this type (where the defendant cannot be included or excluded because some but not all of the defendant’s characteristics have been identified in the sample) can be presented without any statistical analysis whatsoever. See Commonwealth v. Mattei,
The product rule refers to the product of the frequencies, or probabilities, with which each allele in a tested sample of DNA occurs in a relevant population database. “The resulting number is the probability of someone’s having the same characteristics as the sample tested.” Gaynor,
The victim had different alleles at that location.
Nor was the sample unreadable in the other locations tested.
For the same reasons, we consider harmless error the judge’s failure to provide a Daubert-Lanigan hearing on the statistical evidence presented here.
There were no other witnesses besides the girls to the other sexual as
The appellate prosecutor was not the prosecutor at trial.
Appellate analysis of the effect of improper argument is not the equivalent of “appellate fact-finding” as suggested by the dissent. A key factor in this analysis is whether there is overwhelming evidence of guilt. See Kater, supra. See also Commonwealth v. Santiago,
Other aspects of the closing reflected a generally “overwrought” tone consistent with these emotional appeals. See Commonwealth v. Deloney,
We likewise consider the jury able to evaluate with appropriate detachment the prosecutor’s statement: “Ladies and gentlemen, for you to believe the defendant’s theory of this case, everybody — everybody else is lying.” The defense had in fact argued that the victims “were not lying when they testified. They believed what they said was the truth.” Similar statements were made in regard to the other witnesses. The defense was essentially that the other witnesses jumped to the wrong conclusion when the defendant was found in bed with the girls. The prosecution, however, has no obligation to accept the suggestibility argument in these circumstances. It was free to argue instead as it did that “[t]he truth ... is not something that can be manipulated or suggested [but rather] is something that stands on its own.” The judge’s instructions left no doubt that it was the jury’s responsibility to decide who was telling the truth. Neither side’s ruminations on the issue presented any possibility of confusing the jury.
Dissenting Opinion
(dissenting). As the majority notes, the prosecutor’s
It is the government’s obligation to conduct criminal trials fairly. This closing by the Commonwealth’s attorney was not fairly delivered. The government’s attorney has a “privilege and duty to argue the public’s case aggressively and resourcefully. However, this duty does not confer a license for impermissible argument.” Commonwealth v. Earltop,
“is the representative not of an ordinary party to a controversy, but of a sovereignty whose obligation to govern impartially is as compelling as its obligation to govern at all; and whose interest, therefore, in a criminal prosecution is not that it shall win a case, but that justice shall be done. As such, he is in a peculiar and very definite sense the servant of the law, the twofold aim of which is that guilt shall not escape or innocence suffer. He may prosecute with earnestness and vigor — indeed, he should do so. But, while he may strike hard blows, he is not at liberty to strike foul ones. It is as much his duty to refrain from improper methods calculated to produce a wrongful conviction as it is to use every legitimate means to bring about a just one.”
Berger v. United States,
I recognize full well that reversal of the convictions in this case because of the egregious errors in the prosecutorial closing argument would constitute an extraordinary measure. The majority, in a well-crafted analysis, effectively marshals the evidence, which, I acknowledge, appears to establish that the defendant was guilty on certain of the indecent assault and battery charges. However, even “where there was much evidence of the defendant’s guilt,” a highly improper and prejudicial closing argument by the prosecutor compels reversal. See Commonwealth v. Smith,
“[I]t is not the appellate court’s function to determine guilt or innocence. . . . Nor is it to speculate upon probable reconviction and decide according to how the speculation comes out. Appellate judges cannot escape such impressions. But they may not make them sole criteria for reversal or affirmance. Those judgments are exclusively for the jury. . . . And the question is, not were they right in their judgment, regardless of the error or its effect upon the verdict. It is rather what effect the error had or reasonably may be taken to have had upon the jury’s decision. The crucial thing is the impact of the thing done wrong on the minds of other men, not on one’s own, in the total setting.”
Kotteakos v. United States,
In considering whether there was such prejudicial error, I analyze the factors set forth in Commonwealth v. Santiago,
For these reasons, in my judgment, the deep prosecutorial errors in the closing were so prejudicial as to warrant reversal. I understand the majority differs and rejects that there was prejudicial error because, according to the majority’s calculation, the evidence was overwhelming and “the verdict was reflective of the jury’s discernment and deeply rooted in the evidence, and it need not be overturned due to prosecutorial errors.” Ante at 811.
Even apart from my disagreement concerning the lack of prejudicial error arising from this closing, I differ, respectfully, from the majority affirmance for another, separate reason. That is, in a case such as this, notwithstanding that there may be strong evidence of guilt making it difficult for a defendant to show direct prejudice, there existed governmental errors that were so fundamental and so negative as to affect the fair conduct of trial. When there is this kind of error, I would look to, and invoke, the analysis that is applied in cases where such error is likened to a structural “defect affecting the framework within which the trial proceeds.” Arizona v. Fulminante,
In conclusion: first, because I believe there was prejudicial error
The improper statements in the prosecutor’s closing are set forth in the majority opinion and will not be repeated here.
“Having been told the argument was impermissible beforehand, the prosecutor cannot cloak himself in ‘good faith.’ ” Commonwealth v. Rodriquez,
In accord with such judicial scrutiny, our courts have reversed convictions in cases where the prosecutorial closing exceeded the bounds. See, e.g., Commonwealth v. Coren,
“At no time did the judge focus on the transgression[s] at issue.” Commonwealth v. Beaudry,
“The opening statements and the closing arguments that were just given by the lawyers, those are not evidence. The opening statementand the closing arguments are intended only to assist you in understanding the evidence and the contentions of the parties.”
The prosecutor’s closing misstatements should also, I suggest, be considered in light of the evidentiary error with respect to the DNA evidence. On this, the majority notes as follows:
“In sum, the statistics offered were not authorized by Commonwealth v. McNickles, [434 Mass. 839 (2001)], or the other DNA cases. Rather, the statistics were meaningless and improper. The jury would, however, have wondered why they were being presented. The prosecutor appeared to be arguing that the expert’s testimony was that the “genetic profile [of] what is in the perianal evidence is . . . very, very, very rare . . . [and] is highly inculpatory,” because the chances for “someone else to have contributed the DNA ... are one in a cabillion.” Essentially, the prosecutor seemed to be contending that, because the DNA profile of the perianal sample was exceptionally rare, and the defendant met part of the profile, it was highly likely that the DNA was the defendant’s. This was of course inaccurate and misleading. The DNA profile reflected a mixed sample, not one person’s. The likelihood that the defendant contributed to the mixed sample analyzed was not in any way calculated. The judge therefore abused her discretion in allowing the Commonwealth to offer statistics based on a product rule calculation over the repeated objection of the defendant. The question then becomes whether the error was harmless.
“[However, g]iven the overwhelming evidence of the sexual assaults and the defendant’s acquittal on the rape charges, [the majority] conclude^] that the defendant was not prejudiced by the Commonwealth’s improper use of the product rule statistics.”
Ante at 806. For the reasons stated, I differ.
