OPINION
{1} Defendant William Mark Mann appeals his conviction for intentional child abuse resulting in death. The Court of Appeals affirmed Defendant’s conviction. State v. Mann,
I. Facts and Background
A. The Trial
{2} The victim was the six-year-old son of Defendant and Rita Yancher. Yancher had primary custody of the victim, and the victim usually spent every other weekend with Defendant and Patricia St. Jeor Mann, at the time, Defendant’s girlfriend. On August 29, 1996, the victim was present at Defendant’s house. At about 11:00 p.m., Defendant and Yancher argued during a telephone conversation regarding the victim staying with him through Saturday as well as late child support payments. At approximately 1 a.m., on August 30th, St. Jeor awoke and saw Defendant going to the victim’s room to take him to the bathroom. She heard a noise from the victim, followed by a loud crash and a scream. She ran to the bathroom and saw the victim, apparently having a seizure, on the floor with Defendant cushioning his head. St. Jeor called 911 and reported that the victim was injured. She returned to the bathroom and saw the victim on his back with a screwdriver protruding from his chest. St. Jeor testified that the victim was trying to move himself and Defendant was cupping the screwdriver. St. Jeor, a nurse, attempted to attend the victim, but Defendant punched her in the eye, grabbed her by her hair and by the back of the neck and “slammed” her through the door into the opposite wall. She again called 911, telling them that Defendant attacked her.
{3} Paramedics arrived and saw St Jeor exit the house; she was bleeding from her face and had a swollen eye. A paramedic testified that Defendant growled, refused to let him treat the victim, and told him to leave the house. Upon the arrival of sheriffs deputies, Defendant was separated from the victim, and the victim was taken to the hospital. Medical personnel were unable to revive the child. The paramedics and medical personnel testified that they did not disturb the screwdriver from his chest while performing CPR and other medical treatment.
{4} The victim’s cause of death was the stab wound in his chest. Almost the entire screwdriver’s blade, approximately four inches, was embedded in his chest; an autopsy revealed that the screwdriver was wedged between the sternum and the second and third ribs. The victim had two wounds in his chest but only one entry wound, indicating that the screwdriver was withdrawn several inches but not fully removed before it was thrust into his chest a second time. A pathologist testified that there was blood in both the right and left chest cavities, indicating that the wounds occurred prior to the victim’s death. The pathologist testified that “there [were] two trajectories that emanate from one entrance hole, one stab wound with two trajectories.” He concluded that the victim’s wounds were “stabbing paths that were created by a stab into the right chest, a partial withdrawal and then a stab into the left chest.” The pathologist testified that the screwdriver could not simply move over into the left chest because the vertebral column protrudes into the cavity; thus, the screwdriver had to be withdrawn until it was above the range of the column and then reintroduced. He also testified that cardiopulmonary resuscitation compressions to the chest, as well as other medical interventions performed on the victim, could not have caused the second wound path. There were no other injuries on the front of the victim’s head, face, hands, or elbows.
{5} Defendant was also charged with child abuse for a head injury the victim suffered in 1994. The State’s pathologist testified regarding the victim’s earlier skull fracture. He concluded that the brain injuries he observed were inconsistent with a simple fall from a bar stool as described by Defendant.
{6} Defendant testified that he got up around 1 a.m. and realized that he had not taken the victim to the bathroom, a routine occurrence. He woke up the victim and walked him into the bathroom. Defendant testified that he was standing in the bathroom doorway when he saw the victim trip on a rug, put out his arms and knock the items on the hamper, and then fall to the floor. Defendant testified that he toned the victim over and saw the screwdriver. Defendant said he grabbed the screwdriver to prevent the victim from pulling it out in order to minimize the injuries. Defendant testified that St. Jeor came back in and that he thought that she would try to move him, so he pushed her from him and told her to get away. He testified that he did not remember hurting her.
{7} Defendant presented the testimony of Dr. Alan Watts, a physicist, regarding the possibility of the victim impaling himself on the screwdriver consistent with Defendant’s explanation of events. He performed several calculations in the courtroom relating to the angle at which the screwdriver may have landed and the amount of force which the victim’s body would have exerted upon it on impact, as well as videotaped and live demonstrations for the jury. The videotape consisted of Dr. Watts performing experiments in which he dropped a metal rod, which simulated the victim’s body, and a screwdriver onto the concrete floor of his garage. Dr. Watts analogized how a screwdriver might bounce if it hits a solid object with the randomness of throwing dice. Dr. Watts testified that the occurrence of an impalement such as that described by Defendant has “a relatively small overall probability.” He stated that, based on the “probability aspects of this,” it would be a “freakish accident.” Dr. Watts said that “[i]t is a probability calculation” and he offered an example for comparison to “Monte Carlo [codes] because basically you roll the dice.”
{8} The State did not present rebuttal testimony, but instead cross-examined Defendant’s expert. Dr. Watts conceded that he was unable to explain from his calculations how the second wound path occurred, stating that he had “no way of calculating how the second path could have been caused on the basis of physics.” The prosecutor asked if Dr. Watts could calculate “the probability of [Defendant’s] explanation of the stab wound.” Dr. Watts testified that he did not calculate the probability of impaling oneself on a screwdriver because “the whole issue that [he] was asked to address was can this happen, and the answer is, yes, it can.” He said that the probability would be “finite,” but “never zero.” Dr. Watts testified that if he “were to run every option possible, [he’d] come to the conclusion that on average you won’t stab yourself by falling on a screwdriver, but there is nevertheless a finite possibility it can happen.”
{9} A jury convicted Defendant of child abuse resulting in death and second degree murder arising from the death of the victim. The jury also convicted Defendant of aggravated assault of a household member, St. Jeor. The jury deadlocked on the child abuse charge stemming from the victim’s 1994 head injury.
B. The Jurors’ Statements
{10} Defendant filed a motion for a new trial, arguing that the verdict was tainted by juror misconduct. Defense counsel interviewed several jurors and was told that Juror 7 presented probability calculations to the other members of the jury regarding the chances of a child and a screwdriver falling in such a manner as to result in impalement. Defendant identified several jurors who he believed had information regarding Juror 7.
{11} The trial court decided to conduct in camera interviews on the record with members of the jury to determine if an evidentiary hearing was necessary because the trial court was concerned with the jurors’ privacy after videotape of the jury had appeared on television during the trial. The court gave Defendant the opportunity to name the jurors whom the court should question and gave both Defendant and the State the opportunity to posit any additional question to be asked. Defendant did not request that the trial court interview all members of the jury. The Court interviewed Jurors 4, 6, 7, 9, and 10.
{12} Juror 9 said that Juror 7 wrote “some calculations” on a board in the jury room, and said,
But, see, I kind of viewed that more as here is a guy that knows numbers, knows mathematics, who knows probabilities. I viewed it as his life experience. You know, much in the same way that relating back to the ’94 head injury ... where the one juror ... brought in his life experience. He didn’t bring in something, but in effect he did bring in something. He brought in the fact that he had a kid fall out of a tree and had a bad head injury____ [W]e had nurses in there, and the nurses brought in their life experience____”
{13} Juror 4 noted that Juror 7 “didn’t say he did any experiments at home” and that “[h]e didn’t bring papers” into the jury room, but used the easel in the room. Juror 4 recounted that Juror 7 said, “ ‘Let’s take Dr. Watts’ figures.’ And you might fly this by that — being an engineer and probably halfway [physicist], he said using his figures, it can’t come out the way he said it did.” Juror 10 stated that Juror 7 had some “figures that he had thought about and it was explaining his point of view on the testimony of Dr. Watts.” Juror 6 stated that “I feel that the particular juror that — the engineer juror, to me that was just his way of venting his feelings and thoughts and emotions during the deliberation.”
{14} Juror 7 told the trial court that he did not do any calculations or experiments at home. He contended that he did not dispute or discredit Dr. Watts’ testimony but believed that Dr. Watts’ testimony consisted of “fine calculations and [he] would agree with the calculations.” Juror 7 thought that the testimony did not “[answer] the right question” because he did not accept the “logical tie” between the testimony and Defendant’s story. Juror 7 completed a probability calculation to “verify [his] own gut feeling,” beginning with Dr. Watts’ calculations which were presented during the trial. He stated that he used his “professional judgment” and a “fairly simple five-step probability” calculation with five events from Defendant’s description of the event: first, whether “the screwdriver land[ed] in the correct orientation” or “solid angle” perpendicular to the victim’s falling body; second, whether the screwdriver landed with the blade facing up; third, whether the screwdriver separated itself, as it fell, from other items that had been knocked off the hamper; fourth, where it landed on the floor; and fifth, whether its orientation caused the wound path. He recounted, “I simply multiplied the numbers, one over 10 times one over two times 1 over 100 three times, and the number you get is basically five times ten to minus 8 or in what most of us think about, one in a 20 million chance.”
{15} The trial court stated,
I conducted several interviews with the jurors in this case. My concern and purpose for doing that was first of all to find out if there was any juror misconduct requiring possibly a full evidentiary hearing as to the merits of the Defendant’s motion as to whether that misconduct may have influenced the jury to the extent the Defendant might be entitled to a new trial in this case.
Also, another reason for my interviews with the jurors were to find in my own mind as to whether anything occurred in the jury room that was such that would require that in the interest of justice that I would have to remedy or should remedy what could be characterized as a manifest miscarriage of justice.
{16} The trial court expressed
after the most serious contemplation, I find that there has not been sufficient evidence before this Court to require either a further inquiry into the jury’s conduct, nor is there such that would require me in my role as a judge to set aside that verdict. I feel I believe in the jury system. I believe that the jury in this ease took the evidence as they saw it in court, made a decision based on their [consciences] and on the evidence presented in court, although some people may feel that they would have come to a different resolution. That is not what our system is about, and for me to place myself in the stead of the jury to overturn that would be, I feel, [betrayal] of everything I believe about our system.
The trial court then denied Defendant’s motion. The trial court found that Defendant failed to meet his burden to demonstrate that extraneous information had reached the jury, stating that there was insufficient evidence to require further inquiry into the jury’s conduct or to set aside the verdict. A majority of the Court of Appeals affirmed the trial court on the issue of juror misconduct, concluding that the trial court did not abuse its discretion by denying Defendant’s motion for a new trial. Mann,
II. Discussion
A. Juror Conduct
1. Standard of Review
{17} This Court will not overturn a trial court’s denial of a motion for a new trial unless the trial court abused its discretion. State v. Volpato,
2. Extraneous Prejudicial Information
{18} The competency of a juror as a witness is specifically governed by our Rules of Evidence.
Upon an inquiry into the validity of a verdict ..., a juror may not testify as to any matter or statement occurring during the course of the jury’s deliberations or to the effect of anything upon that or any other juror’s mind or emotions as influencing the juror to assent to or dissent from the verdict ... or concerning the juror’s mental processes in connection therewith, except that a juror may testify on the question whether extraneous prejudicial information was improperly brought to the jury’s attention or whether any outside influence was improperly brought to bear upon any juror.
Rule 11-606(B) NMRA 2001. Thus, a juror may testify on the very limited circumstance of whether extraneous prejudicial information was improperly before the jury. Otherwise, the rule prohibits a juror from testifying as to any matter or statement made during the course of deliberations or to the juror’s mental processes.
{19} The party requesting a new trial on the basis that the jury was exposed to extraneous information “must make a preliminary showing that [he or she] has competent evidence that material extraneous to the trial actually reached the jury.” State v. Sena,
{20} Although several prior New Mexico cases, as well as some cases from other jurisdictions, do not distinguish jury tampering, juror misconduct, and juror bias, we believe it would provide clarification to do so. While there is bound to be overlap between these categories, we find the distinctions useful to place the issue in the present case into proper context. See generally Webster,
{21} Jury tampering generally refers to private communications between third persons and jurors. The United States Supreme Court has held that private communication, contact, or direct or indirect tampering with a juror during a trial about the matter pending before it, “if not made in pursuance of known rules of the court and the instructions and directions of the court made during the trial, with full knowledge of the parties” may result in a due process violation. Remmer v. United States,
{22} Juror misconduct, on the other hand, includes activity by members of the jury which is inconsistent with the instructions by the court. See Sena,
{23} In State v. Sacoman,
{24} The Court, in Sacoman, expressed a rather broad introductory statement: “[c]ommunication of specific knowledge from a particular juror to others involves extraneous information.” Id. at 590,
{25} Sacoman also relied on cases which involve juror bias, State v. Larue,
{26} The relationship between voir dire and juror bias demonstrates the distinctions between the juror’s actions in Larue and the present case. During voir dire, the parties and the court in Larue questioned venire members regarding sexual abuse. Larue,
{27} We emphasize that the underlying issue in cases involving extraneous information is a defendant’s right to a fair and impartial jury. Jury tampering and juror bias present the clearest examples of potentially improper influences upon a jury, while the notion of juror misconduct creates a more difficult extension of the issue. See United States v. Dutkel,
3. Juror 7’s Conduct
{28} As discussed below, we conclude that Juror 7’s statements constituted proper deliberations based upon his professional and educational experience. Defendant argues that Juror 7 injected new evidentiary facts which contradicted defense testimony rather than expressing opinions, views or beliefs about the evidence. We disagree. Defendant concedes that Juror 7 began with Dr. Watts’ testimony, but he asserts that Juror 7 “added his own testimony of probability and physics.” See Mann,
{29} In order to provide expert testimony supporting Defendant’s version of events, Dr. Watts described basic physics principles, completed extensive calculations, and performed both in-court and videotaped demonstrations with a screwdriver and other materials. Dr. Watts testified that the occurrence of an accidental impalement consistent with Defendant’s theory has “a relatively small overall probability.” Dr. Watts testified that, based on the “probability aspects” of this scenario, the victim’s accidental impalement would be a “freakish accident.” On cross-examination, Dr. Watts testified that he did not calculate the actual probability of impaling oneself on a screwdriver because the specific issue Defendant wished for him to address was whether the scenario could possibly happen. However, Dr. Watts did give his expert opinion regarding the probability of such an accidental impalement as “finite,” but “never zero.” Dr. Watts testified that if he “were to run every option possible, [he’d] come to the conclusion that on average you won’t stab yourself by falling on a screwdriver, but there is nevertheless a finite possibility it can happen.” Dr. Watts analogized how a screwdriver might bounce into position to the randomness of throwing dice; he compared the probability calculation to “Monte Carlo codes” which are “named after the gambling place.” Defendant himself placed probability calculations regarding his accidental impalement theory in evidence before the jury.
{30} Juror 7 articulated his own thought process as to what this “finite” probability calculation would be, based on the evidence presented in court and based on Dr. Watts’ testimony. Mann,
{81} In Chamberlain,
{32} “In deciding every case, jurors must necessarily take into consideration their knowledge and impressions founded upon experience in their everyday walks of life, and the fact that these things affect them in reaching their verdict cannot be reversible error, because, indeed, jurors without possessing such knowledge and impressions could not be had.” State v. Dascenzo,
{33} Remarks made by the jurors in the present case illustrate the problematic application of a broad definition that communication of specific knowledge from a particular juror to others constitutes extraneous prejudicial information. Juror 9 described how another juror discussed that juror’s experience with his own child falling from a tree and how that experience related to Ms understanding of the child abuse charge stemming from the victim’s 1994 head injury. Both Juror 9 and Juror 7 mentioned that two jurors who were nurses discussed their opinion regarding the expert medical testimony, based on their educational and professional experience. Finally, Juror 7 described another juror recounting a previous experience in which the juror fell straight forward and sustained an injury to her chin. All of this information was not subject to cross-examination regarding the similarity or dissimilarity to the charges in the present case; it could be considered extraneous under tMs definition. The examples from the present case illustrate the difficulties inherent in attempting to distinguish extraneous information from permissible deliberation based on life experience. This highlights the importance of allowing our jury system to function without improper interference, and the critical need for tMs Court to protect open, full, and complete deliberations among members of the jury.
{34} Defendant argues that the Court of Appeals opinion will result in the “dumbing down” of juries because attorneys will remove individuals such as Juror 7. We disagree. We do not believe that because an individual has particular professional experience or is well-educated one can assume that he or she is biased in favor of any particular party. As discussed above, venire members who express experiences which would affect their ability to be unbiased can be dismissed through cause challenges during voir dire. If either party wishes to remove a member of the venire because of that individual’s life experience, or educational or professional background, as a matter of strategy, the party will have to do so with a peremptory challenge. These factors, without more as determined by the trial court, will not provide a basis for challenging such individuals for cause and will not subject a jury verdict to attack. Accepting Defendant’s argument that an articulate juror who expresses and explains his or her reasoning based on properly admitted evidence results in extraneous information prejudicing the jury would, we believe, surely result in a chilling effect on jury deliberations. Mann,
{35} Juror 7 discussed evidence and testimony properly admitted at trial and performed calculations similar to those of Defendant’s expert. See Chamberlain,
{36} However, we do note that it appears that the United States Supreme Court has distanced itself from the Remmer presumption of prejudice upon which New Mexico courts have relied. See Olano,
{37} As a final matter, Defendant argues that his right of confrontation was violated and makes an unsupported argument regarding his right to be present while the trial court questioned the jurors. Because, as we explained above, we conclude that no extrinsic evidence was before the jury, Defendant was not deprived of his right of confrontation. The trial court’s in camera interviews were within its discretion. See Commonwealth v. Fidler,
III. Conclusion
{38} Defendant failed to demonstrate that extrinsic information actually reached the jury. We conclude that the trial court did not abuse its discretion in denying Defendant’s motion for a new trial. The trial court acted within its discretion with respect to Defendant’s motion for a new trial. A juror may properly rely on his or her education, experience and common sense during deliberations; thorough discussion, informed by expertise and based on evidence at trial, does not constitute extraneous prejudicial information. Under Rule 11-606(B), such information concerning the juror’s mental processes is not properly the subject of juror testimony. Thus, we affirm Defendant’s conviction.
{39} IT IS SO ORDERED.
Notes
. Defendant does not argue that the New Mexico Constitution provides greater protection, and we do not address this question.
. Unlike the juror with busboy experience, the Sacoman juror who related a false story could more accurately be described as a potentially biased juror. See Sacoman,
