COMMONWEALTH vs. MICHAEL GRINKLEY.

KAFKER, J. 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 involving

Page 799

the defendant and two minors, his great nieces. The defendant was indicted on four counts of natural sexual intercourse with a child under the age of sixteen and seven counts of indecent assault and battery of a child under the age of fourteen. After a jury trial in December, 2005, he was found guilty of four lesser included offenses of indecent assault and battery of a child under the age of fourteen on the indictments charging statutory rape, but he was found not guilty on the three remaining, separately charged indecent assault and battery counts. [Note 1] On appeal, the defendant argues that his convictions should be reversed because (1) the judge improperly allowed an expert witness to testify to an irrelevant and misleading DNA statistic and (2) the prosecutor's closing argument was improper because it appealed to juror sympathies and misrepresented the defense argument.

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. [Note 2] Also residing in the home were the victims' grandmother Celeste, their grandfather Chester, their five year old brother, and two adult cousins, Tosheiya and Lakeisha (the victims' first cousins, once removed). The defendant was the victims' great uncle (their grandmother Celeste's brother), who lived in the third-floor apartment of the home. Because Celeste, the primary caregiver, was away on the evening of February 10 or 11, Natalie put the girls and their brother to bed together in the girls' room at approximately 9:00 P.M. The older victim was wearing a long T-shirt and underwear. The younger victim was wearing pajama pants with a small rip near the crotch area. After tucking them in, Natalie went up to the defendant's room to smoke a cigarette with several family members and friends, including her cousins. Although some of the men had been consuming alcohol, testimony indicated that the women were not drinking that evening.

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

Page 800

bed, "unzipped his fly and pulled out his private spot" (later described by the child as his penis). He moved the covers down to her knees, and climbed on top of her. The defendant then slid her underwear down, at which point "[h]is private spot went up to mines." She felt the defendant's penis "moving around" on top of her vagina. After a period of time, the defendant climbed off her and moved onto her sister, the younger victim. The older victim felt a part of the bed going down and his leg next to her. She then went back to sleep.

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. [Note 3] The defendant's pants were at least partially undone and Natalie stated that his buttocks were exposed. Natalie was also able to see the younger victim's bare legs underneath the defendant, while Tosheiya testified that she could see the younger girl's exposed buttocks. Natalie asked the defendant what he was doing, prompting him to respond brazenly: "Ha-ha. You know how that goes." Lakeisha similarly stated that when discovered, the defendant said "Ha-ha-ha. You know how we do." Tosheiya asserted that she heard the defendant respond " 'Don't act like you don't know how it goes down in this family,' or something to that effect."

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.

Page 801

When the police arrived later that evening, the two victims were taken to the Boston Medical Center for the administration of a sexual assault evidence collection kit. The resulting forensic samples were forwarded to the Boston police crime laboratory (laboratory) for processing and DNA testing.

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

Page 802

individual's alleles were the same as those present at the loci in the DNA samples tested. [Note 4]

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. [Note 5] The profile found in that sample was an "inclusion" for the older victim; her alleles were the same as those identified at every location tested. The defendant was neither included nor excluded as a contributor of the additional DNA found in the

Page 803

sample. [Note 6] Five of his alleles were possible matches to alleles found in the sample that could not have been contributed by the older victim. Twelve alleles of the defendant were not found in the sample. [Note 7] No allele was detected that could not have been contributed by either the older victim or the defendant. The older victim's alleles were also darker, thereby indicating that she was the primary contributor to the sample. [Note 8]

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. Merrill Dow Pharms, Inc., 509 U.S. 579 (1993); Commonwealth v. Lanigan, 419 Mass. 15 (1994), regarding the statistical methodology, all of which were denied, the prosecution was permitted to offer Lynch's statistical opinion that only approximately "one in three hundred and twenty billion African-Americans . . . are included as being possible contributors to the mixture detected on that sample." [Note 9] Lynch explained that that meant "basically a fraction of one percent of the population . . . could be expected to have contributed their entire DNA profile to [that] particular mixed piece of evidence." On cross-examination, Lynch acknowledged that the defendant was not included within the one in three hundred and twenty billion African-Americans

Page 804

who could be considered a contributor, as his entire profile was not detected in the mixture. In fact, the only identifiable complete DNA profile in the mixture was that of the older victim. The statistics were therefore irrelevant and potentially confusing and misleading.

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. [Note 10] What the Commonwealth submitted here, ostensibly product rule statistics for a mixed sample without an identified primary contributor, was not permissible for reasons that should have been obvious.

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. [Note 11] Commonwealth v. Lanigan, 419 Mass. at 20, 21; Commonwealth v. Gaynor, 443 Mass. 245, 268 (2005). The product rule has been held to be a scientifically valid method for calculating frequency profiles involving single source (i.e., nonmixed) DNA samples. See Commonwealth v. Rosier, 425 Mass. 807, 815-817 (1997). Statistics derived from the product rule have also recently been held valid in mixed sample contexts "where the [DNA] analyst can distinguish between a primary and a secondary contributor in a mixed sample, and thereafter treat the primary contributor as a single source for statistical purposes." Gaynor, supra at 268. In the instant case, the sample was mixed. The defendant was not identified as a primary contributor and therefore

Page 805

the sample was not treated as originating from a single source. Moreover, if a primary contributor could have been identified, it would apparently have been the older victim. To apply the product rule to a mixed sample without a primary contributor having been identified as a single source makes absolutely no sense. See id. at 250 (frequency calculations using product rule computations were not performed on some samples because "samples comprised a mixture of DNA consistent with the profiles of both the victim and the defendant, and a primary contributor could not be identified").

The prosecutor argued to the judge at trial that the statistical evidence here was justified by Commonwealth v. McNickles, 434 Mass. 839 (2001), contending that it was "exactly the same statistic." The McNickles case, however, concerned the use of likelihood ratios, not product rules. See, e.g., id. at 845-848; Commonwealth v. Gaynor, 443 Mass. at 268. The likelihood ratio "compares the probability that the defendant was a contributor to the sample with the probability that he was not a contributor to the sample." Commonwealth v. McNickles, 434 Mass. at 847. It is appropriately used for statistically evaluating the "test results of mixed samples when the primary and secondary contributors cannot be distinguished." Commonwealth v. Gaynor, supra. It is undisputed that the laboratory here, however, lacked the capacity to compute likelihood ratios. There was no attempt to calculate such ratios in this case.

In Commonwealth v. McNickles, 434 Mass. at 851-854, the Commonwealth also introduced evidence that the defendant's alleles matched the alleles identified at one location of a PCR test of a mixed sample. [Note 12] The rest of the locations examined were not readable. The Commonwealth also provided statistics regarding the frequency of those alleles at that location, which was one in 1,000 for Caucasians and one in 100 for African-Americans. The court stated: "That a scientific test provides descriptive information short of a definitive identification does not make it unreliable, irrelevant or otherwise inadmissible." Id. at 854. The court also stressed that "[a]t no time did the Commonwealth exaggerate the significance of having the same type at the single . . . site or otherwise suggest that the PCR-based testing itself

Page 806

identified the defendant as the perpetrator." Id. at 854-855. No such limited DNA evidence or qualified statistics were, however, introduced here. [Note 13]

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. [Note 14] The defendant was found in bed on February 10 or 11 with several young children. His pants and zipper were down while he lay on top of the younger victim, whose pajama bottoms had also been pulled down. He also made inculpatory remarks when he was discovered. The girls described the different sexual assaults in some detail. Although the DNA evidence taken from the perianal sample arguably added proof not otherwise present of a rape of the older victim, it was totally unnecessary to the mountain of proof provided to establish the sexual assaults by the defendant. [Note 15]

Page 807

4. Closing argument. The defendant claims that the prosecutor's closing argument compounded the error regarding the DNA statistics and contained improper emotional appeals and misrepresentations of defense positions. [Note 16] To determine whether prejudice resulted from the error, "we consider (1) whether the defendant seasonably objected; (2) whether the error was limited to collateral issues or went to the heart of the case; (3) what specific or general instructions the judge gave to the jury that may have mitigated the mistake; and (4) whether the error, in the circumstances, possibly made a difference in the jury's conclusions." Commonwealth v. Kater, 432 Mass. 404, 422-423 (2000). In making this determination, we consider "the entire record, including the balance of the prosecutor's argument." Id. at 423, quoting from Commonwealth v. Kozec, 399 Mass. 514, 523 (1987). [Note 17]

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. at 519 n.9.

Page 808

See also Commonwealth v. Bradshaw, 385 Mass. 244, 277 (1982) ("We have on more than one occasion requested that prosecutors seek redress from the trial judge rather than resort to retaliatory reply to an improper defense argument").

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, 59 Mass. App. Ct. 47, 53 (2003), we stated that this very same prosecutor's "references to 'how hard' it must have been for [the victims and parents] to testify . . . crept perilously close to the line separating a proper discussion of the evidence from an improper appeal to jury sympathy." See ibid. Despite that warning, the prosecutor adopted the same approach here, stating: "Don't underestimate for one second how hard it was for those little girls to come into this courtroom, in front of this court, in front of all of you strangers, get up on the witness stand, and talk about the private intimate details of their victimization at the hands of this child rapist." The prosecutor stated further: "Think about literally how hard it was for [the younger victim] to talk. . . . The shame she felt. She couldn't talk about it. She needed to write it down and then read it."

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

Page 809

been like for [the older victim] that night after he had gotten on top of her. . . . Think about what life was like for [the younger victim]. She sees it done to her big sister, and her sister doesn't do anything about it." Although the actions described were arguably grounded in the evidence, it is not clear what purpose was served by the statements that the jurors were to "think about what it must have been like" for the victims except to have them place themselves in the children's position. "The invitation to the jury to put themselves in the position of the victim is usually improper." Commonwealth v. Jordan, 49 Mass. App. Ct. 802, 816 (2000). See Commonwealth v. Harris, 11 Mass. App. Ct. 165, 176 & n.9 (1981) (remarks such as "[t]hink of what [this eleven year-old girl] went through by giving this story. Do you think she wanted to put herself through this? Please don't let her down" were "improper attempt[s] to arouse juror sympathy").

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 conceivable

Page 810

relevance there was to a description of the difficulty and pain of a rape examination was outweighed by its prejudicial effect. See Mass. G. Evid. § 403 (2009-2010 ed.) Although goaded by the defense, the prosecution capitalized on the opportunity by drawing out its details as part of an over-all emotional appeal to the jury. As explained above, the prosecutor should have objected to the defendant's argument or explained its implausibility without trying to exploit it. [Note 18]

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

Page 811

sexual assaults and acquitted him on the rape charges. See Commonwealth v. Bradshaw, 385 Mass. at 277 (where "most of the prosecutor's remarks were grounded in the evidence and the few extravagant remarks were responsive to equally extravagant defense tactics in final argument. . . . [t]he jury could be expected to take both arguments with a grain of salt"); Commonwealth v. Kozec, 399 Mass. at 517 (properly instructed jurors considered able to sort out excessive claims of both parties and separate argument from evidence where "they in part rejected the position of each side, returning a verdict of not guilty on one charge and guilty on the other"). [Note 19]

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., 382 Mass. 387 (1981). We understand that these are hotly contested cases in which the stakes and emotions could not be higher. We also understand that the defense was provocative. That being said, "the prosecutor, as a representative of the government, must hold himself [or herself] to a consistently high and proper standard." Commonwealth v. Kozec, 399 Mass. at 519. We do not consider that high and proper standard close to being met in the closing argument here.

Judgments affirmed.

BERRY, J. (dissenting) . As the majority notes, the prosecutor's

Page 812

closing argument was laden with fundamentally unfair and prejudicial statements [Note dissent1] -- a number of which were similar to those that drew criticism to the prosecutor and a forewarning of impropriety from this court in Commonwealth v. Deloney, 59 Mass. App. Ct. 47, 53 (2003). [Note dissent2] Given the host of prosecutorial errors in the closing, in my opinion, the defendant's due process rights to a fair trial under art. 12 of the Massachusetts Declaration of Rights and the Fifth Amendment to the United States Constitution were tread upon.

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, 372 Mass. 199, 205 (1977) (Hennessey, C.J., concurring). The attorney for the government must be and "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, 295 U.S. 78, 88 (1935). This essential governmental obligation and the constitutional due process right underlying the conduct of criminal trials by the government are to be protected by the courts.

Page 813

Where improper arguments presenting " 'prosecutorial errors' are offered in case after case[, i]t is my thought that this court should in the future stand more ready to reverse the judgments in such cases, particularly when it appears that the simple precautions suggested herein have not been invoked." Commonwealth v. Earltop, supra at 207 (Hennessey, C.J., concurring). The freewheeling argument in this case reflected none of the precautionary measures against prosecutorial error penned by Chief Justice Hennessey in Earltop. It may be said -- particularly in light of the warnings posted in Commonwealth v. Deloney, supra -- that this closing, rather than being delivered with any precaution, was delivered with recklessness.

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, 387 Mass. 900, 912 (1983). Guilt or innocence is not the province of appellate review.

"[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, 328 U.S. 750, 763-764 (1946) (citations omitted). Accord Commonwealth v. Alphas, 430 Mass. 8, 21 (1999) (Greaney, J., concurring) ("Appellate courts do not

Page 814

sit as triers of fact. Any test concerning reversible error that requires an appellate court to determine whether a defendant is actually innocent [or, I would suggest, is actually guilty] is conceptually flawed because such a test converts the appellate function into the jury function in violation of their different purposes"). Rather, it is the rule of law -- including the rule of proper closing argument -- that guides appellate review. [Note dissent3]

Page 815

Rightfully, objection was lodged to this outrageous closing argument -- indeed, a motion for a mistrial was pressed after the closing. Accordingly, appellate review scrutinizes the trial record for prejudicial error. An error will be deemed not to have been prejudicial only if an appellate court with "conviction is sure that the error did not influence the jury, or had but very slight effect. . . . But if one cannot say, with fair assurance, after pondering all that happened without stripping the erroneous action from the whole, that the judgment was not substantially swayed by the error, it is impossible to conclude that substantial rights were not affected." Kotteakos, supra at 764- 765. See Commonwealth v. Flebotte, 417 Mass. 348, 353 (1994). Although the evidence appears strong on the convictions for indecent assault and battery, I cannot with such firm conviction and surety say that the decision of the jury to render guilty verdicts on some but not all of the sexual assault charges was not substantially swayed by the flaws in this prosecutorial closing. Rather, I believe there was present such prejudicial error as to affect the very structure of the trial. See Commonwealth v. Flebotte, supra.

In considering whether there was such prejudicial error, I analyze the factors set forth in Commonwealth v. Santiago, 425 Mass. 491, 500 (1997), cert. denied, 525 U.S. 1003 (1998). In doing so, I conclude that this case does not meet four of the five factors, and the fifth factor is enigmatic -- as it is in any jury split in verdicts. The Santiago factors are analyzed as follows: "[1] whether defense counsel seasonably objected to the arguments at trial [I consider that there was objection in this case]; [2] whether the judge's instructions mitigated the error [I consider that there was no adequate jury instruction here [Note dissent4]]; [3] whether the

Page 816

errors in the arguments went to the heart of the issues at trial or concerned collateral matters [I consider the misstatements in this closing to be directed to core issues]; [4] whether the jury would be able to sort out the excessive claims made by the prosecutor [I consider that the closing errors here were deep and repetitive, and thus hard for a jury to sort out because so pervasive]; and [5] whether the Commonwealth's case was so overwhelming that the errors did not prejudice the defendant [I consider that, if the evidence were deemed to be overwhelming, then one may query concerning the acquittals on various of the related sex offenses]." Ibid. See generally Commonwealth v. Kozec, 399 Mass. 514, 518-519 (1987).

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, 499 U.S. 279, 310 (1991). In other words, even apart from a defendant demonstrating actual prejudice, there are certain errors that may "render a trial fundamentally unfair." Rose v. Clark, 478 U.S. 570, 577 (1986). The governmental misconduct in this case, I believe, was such as to warrant analogy to structural error cases concerning whether a criminal trial did not "reliabl [y] serve as a vehicle for determination of guilt or innocence."

Commonwealth v. Pinckney, 419 Mass. 341, 342 (1995) ("A constitutionally deficient reasonable doubt instruction amounts to a structural error which defies analysis by harmless error standards"). Accord Sullivan v. Louisiana, 508 U.S. 275, 280 (1993). I suggest by analogy to structural error cases -- albeit I acknowledge that the analogy in the context of closing argument is far from perfect -- that the no-prejudicial error analysis which leads to the affirmance of the convictions in the majority opinion cannot be sustained in this case.

In conclusion: first, because I believe there was prejudicial error [Note dissent5] and second, because I believe there was structural error in that core principles governing the conduct of a fair criminal trial were violated by this closing argument, I respectfully dissent.
