The defendant, Robert B. Senior, was convicted of vehicular homicide and sentenced to from three to five years in
1. Background. On April 5, 1997, the defendant met Mends at a restaurant and lounge, where he consumed four to six beers in a two-hour period. At approximately 6:50 p.m., after leaving the restaurant, the defendant drove down Route 44 in excess of the speed limit and crashed into the victim’s car, which had apparently stalled on the roadway. The victim was pronounced dead, of multiple injuries sustained in the collision, at a hospital.
Officers Kevin Furtado and Stephen Viella of the Plymouth police department amved at the scene of the collision, and both spoke with the defendant. Officer Viella testified that the defendant smelled of alcohol, had slurred speech, and was unsteady on his feet. On this basis, he determined that the defendant was intoxicated. Shortly thereafter, Officer Furtado read the defendant the Miranda warnings, which the defendant indicated he understood. Thereafter, in response to Officer Furtado’s questions, the defendant admitted that he had “a couple of beers” and did not see the victim’s car before he struck it. When the officer asked him where he had been drinking prior to these events, the defendant did not respond. This was the only question he failed to answer and, thereafter, he cooperated with Furtado by reMeving his license and registration and answering other questions relating to the accident. After the defendant performed poorly on three field sobriety tests, Officer Furtado also concluded that the defendant was intoxicated and placed
Later that night, the defendant’s attorney
At trial, the Commonwealth’s expert witness, Dr. Guy Vallaro, employing retrograde extrapolation with respect to the results of the blood alcohol content test, estimated that the defendant’s blood alcohol level at the time of the collision was between .099 and .148. Additional facts will be presented with respect to each issue.
2. Admission of the defendant’s blood test results. The defendant first claims that the Commonwealth improperly acquired and introduced, both before the grand jury and at trial, the results of his blood alcohol test, conducted by hospital personnel for the sole purpose of defending against the charge of vehicular homicide. On this basis, the defendant maintains his motion to dismiss the indictment should have been allowed. He sets forth a number of grounds in support of this contention, all of which depend on the hospital personnel qualifying as agents of the defendant and his attorney. These arguments fail because we conclude that the hospital personnel were neither the defendant’s nor the attorney’s agents.
The defendant maintains that the hospital personnel became his agents, i.e., members of his defense team, when they drew and tested his blood at his counsel’s request, as part of the defense effort to gather potentially exculpatory evidence. However, there was no such agency relationship shown between the defendant and the hospital personnel. Commonwealth v. Rosenberg, 410 Mass. 347, 354 (1991). Nothing in the record indicates that the hospital’s employees manifested the requisite consent to act in that capacity. Kirkpatrick v. Boston Mut. Life Ins. Co., 393 Mass. 640, 645 (1985), quoting Restatement
The defendant asserts that the Commonwealth improperly used a grand jury subpoena to obtain the hospital record of the blood test results in violation of SJ.C. Rule 3:08, PF 15, 396 Mass. 1217 (1986), which governed grand jury subpoenas to attorneys.
Additionally, the defendant asserts that, by subpoenaing the test results, the Commonwealth violated “multiple privileges.” Because we do not recognize a statutory patient-physician
Additionally, the defendant argues that the Commonwealth’s actions violated his State and Federal constitutional rights to prepare a defense. The Commonwealth’s subpoenaing of the records did not, in any sense, interfere with the preparation of the defendant’s case. Moreover, while the cases cited by the defendant recognize a constitutional right to prepare a defense,
3. Admissibility of retrograde extrapolation evidence. The defendant next argues that the admission of the retrograde extrapolation analysis of his blood alcohol level was improper because it failed to meet the standards set forth in Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), and adopted in part in Commonwealth v. Lanigan, 419 Mass. 15 (1994). We disagree. The Daubert standard departed from the traditional test under Frye v. United States, 283 F. 1013 (D.C. Cir. 1923), which necessitated that “ ‘the community of scientists involved [must] generally accept[] the theory or process’ for it to be admitted in evidence.” Canavan’s Case, 432 Mass. 304, 310 (2000), quoting Commonwealth v. Cumin, 409 Mass. 218, 222 (1991). Under the Daubert-Lanigan standard, although general acceptance is a relevant factor, it is not the “essential ingredient.” Commonwealth v. Lanigan, supra at 25. Indeed, “[t]he ultimate test ... is the reliability of the theory or process underlying the expert’s testimony.” Id. at 24. Consequently, although a foundation may be laid by showing general acceptance of the scientific theory, “a proponent of
With these principles in mind, we find the evidence of retrograde extrapolation was properly admitted. Contrary to the defendant’s assertion, the Commonwealth provided, through its toxicology expert, Dr. Vallaro, ample evidence that retrograde extrapolation is a reliable method of deterxnining blood alcohol levels. Commonwealth v. Lanigan, supra at 24-25. Specifically, Dr. Vallaro testified to the scientific principles of retrograde extrapolation, which is a mathematical calculation used to estimate a person’s blood alcohol level at a particular point in time by working backward from the time the blood alcohol test was taken, taking into consideration rates of both absorption and excretion. R.J. Kenney, Jr., & T.J. Farris, Motor Vehicle Law and Practice § 24.14 (3d ed. 1998).
The defendant incorrectly maintains that Dr. Vallaro did not “remotely suggest that retrograde extrapolation had any general acceptance for any purpose beyond the monitoring of therapeutic drugs for medical uses.” To the contrary, the record reveals that, although Dr. Vallaro testified that retrograde extrapolation was used in “therapeutic drug monitoring,” he also made clear that “numerous people throughout the country” use retrograde extrapolation to determine an individual’s blood alcohol content at an earlier point in time, and that, in the relevant scientific community, this is a generally accepted method.
He acknowledged that there-is some debate concerning the appropriate variables that should be used in making the calculations. In particular, conservative critics advocate the use of a lower excretion rate, such as .008 per cent an hour instead of .015 per cent an hour, which, after years of experimental research, has developed as a consistent average rate for alcohol excretion. Other critics contest attempts to place a precise value on an individual’s blood alcohol level at an earlier point in time. In response to these concerns, Dr. Vallaro accounted for individual variability by using a well-established range of figures
Dr. Vallaro also demonstrated that his calculation method for the retrograde extrapolation “can be or has been tested.” Commonwealth v. Lanigan, supra at 25. In fact, he testified that the typical elimination rate of alcohol, ranging from .008 to .02 per cent an hour, with an average of .015 per cent an hour, was determined by many years of experimental testing. This typical excretion range had been tested on “many hundreds of people” and documented in published reports. As discussed above, Dr. Vallaro himself conducted controlled experimental testing, and such experimental testing supported the range of variability that he used in ascertaining both the absorption rate and the excretion rate in the instant case.
Dr. Vallaro also indicated that retrograde extrapolation had been the subject of peer review and publication. The experimental data establishing a range of excretion since the 1930’s had been documented by published reports. For example, one peer reviewed article opined that, to account for individual vari
Although in Massachusetts we have implicitly considered the issue of retrograde extrapolation, most recently in Douillard v. LMR, Inc., ante 162, 163 (2001), see Commonwealth v. Smith, 35 Mass. App. Ct. 655, 633 (1993) (prosecutor entitled to think, when referring to retrograde extrapolation in opening statement, that such evidence would be admitted), we have never been asked to address the admissibility of retrograde extrapolation as a matter of law. Several other jurisdictions have admitted similar evidence. See, e.g., Ullman v. Overnight Transp. Co., 563 F.2d 152, 152-156 (5th Cir. 1977); People v. Latto, 304 Ill. App. 3d 791, 803 (1999); Rice v. Merchants Nat’l Bank, 213 Ill. App. 3d 790, 797 (1991) (while not required, retrograde extrapolation admissible); State v. Jensen, 482 N.W.2d 238, 240 (Minn. Ct. App. 1992); People v. MacDonald, 227 A.D.2d 672, 674-675 (N.Y. 1996); State v. Catoe, 78 N.C. App. 167, 169-170 (1985); State v. Fade, 452 N.W.2d 779, 782 (S.D. 1990); State v. McDonald, 421 N.W.2d 492, 494 (S.D. 1988) (State must provide extrapolation back to time of offense for blood test results to be admissible); Hartman v. State, 2 S.W.3d 490, 494 (Tex. Ct. App. 1999); State v. Bradley, 578 P.2d 1267, 1269 (Utah 1978); State v. Dumont, 146 Vt. 252, 254-255 (1985) (“relation back” testimony necessary to establish blood alcohol content at time of actual operation); State v. Carter, 142 Vt. 588, 591-593 (1983).
Given the evidence of reliability presented by the Com
4. Post-Miranda silence. Finally, the defendant claims the judge improperly denied the defendant’s motion in limine to exclude evidence of his failure to answer certain police questions.*
The judge was warranted in finding that the defendant initially “voluntarily, knowingly, and intelligently” waived his right to remain silent by indicating that he understood his Miranda rights and by answering Officer Furtado’s questions after receiving those warnings. Commonwealth v. Freeman, 430 Mass. 111, 115 (1999). See Commonwealth v. Hussey (No. 1), 410 Mass. 664, 671, cert, denied, 502 U.S. 988 (1991); Commonwealth v.
However, “a defendant has not only the right to remain silent from the beginning but also a continuing right to cut off, at any time, any questioning that does take place.” Commonwealth v. Bradshaw, 385 Mass. 244, 265 (1982), and cases cited. The defendant’s failure to answer one specific question “must be interpreted in the context of his willingness to talk both immediately prior to and subsequent to” this particular question. Commonwealth v. Pennellatore, 392 Mass. 382, 387 (1984). The fact that the defendant was silent in response to the question concerning where he had been drinking did not constitute an affirmative indication “that he [was] invoking the right he previously waived.” Commonwealth v. Roberts, 407 Mass. 731, 734 (1990). See Commonwealth v. Pennellatore, supra; Commonwealth v. Ewing, 30 Mass. App. Ct. 285, 287 (1991) (defendant’s decision not to answer particular question did not constitute indication that he was invoking previously waived right to remain silent).
Because we conclude that neither the motion judge nor the trial judge committed any error, we affirm the judgment of conviction.
So ordered.
The defendant timely filed an appeal in the Appeals Court. A single justice of the Appeals Court released him from incarceration and stayed the sentence pending the resolution of this appeal. The Commonwealth unsuccessfully appealed from that order to a single justice of this court who denied its petition under G. L. c. 211, § 3, from which the Commonwealth appealed. Commonwealth v. Senior, 429 Mass. 1021 (1999).
This attorney was not the attorney who represented the defendant at trial and on appeal.
The only evidence that the defendant or the attorney indicated to the hospital’s employees that they expected that the test results would be privileged arises from the Commonwealth’s cross-examination of the attorney at the motion hearing. The attorney responded: “Did I say to them, ‘I want you [as] part of the defense team,’ the answer’s no. Did I retain them or did I request them to conduct the blood alcohol pursuant to attorney-client privilege, that was my understanding and I conveyed it” (emphasis added). The attorney never articulated how he “conveyed” this expectation to the personnel at the hospital.
The current relevant rule, Mass. R. Prof. C. 3.8 (f), 426 Mass. 1397 (1998), was adopted after the subpoena was issued in this case.'It is similar to, yet more detailed than, SJ.C. Rule 3:08, PF 15, 396 Mass. 1217 (1986).
While there is no statutory patient-physician privilege per se, there is a legislatively created policy favoring the confidentiality of medical records. G. L. c. 111, §§ 70, 70E. Section 70, relied on by the defendant, governs a hospital’s maintenance and disclosure of its records. That section provides, in relevant part, that hospitals must maintain “records of the treatment of the cases under their care including the medical history and nurses’ notes,” and that such records shall not be subject to G. L. c. 66, § 10 (concerning inspection of public records), “provided . . . that upon proper judicial order, whether in connection with pending judicial proceedings or otherwise . . . and in compliance with the terms of said order . . . such records may be inspected and copies furnished on payment of a reasonable fee.” Id.
Here, the defendant claims that the Commonwealth did not obtain a judicial order before subpoenaing his records from the hospital, as required by § 70. However, as the Commonwealth correctly points out, the grand jury summons expressly states that “[tjhis medical information is hereby ordered to be produced pursuant to [G. L. c.] Ill, [§] 70,” and this order was signed by a judge in the Superior Court. Moreover, even if the defendant’s blood test results were confidential, and improperly obtained, we have held, at least in the civil context, that a breach of patient-physician confidentiality does not require exclusion at trial. Schwartz v. Goldstein, 400 Mass. 152, 153 (1987).
The defendant’s other claims, including prosecutorial misconduct and improper discovery and admission in evidence under Mass. R. Crim. R 14 (a) (3) (A), 378 Mass. 874 (1979), are without merit.
At the low end of the range, Dr. Vallaro estimated that a person would eliminate alcohol at the rate of .008 grams per one hundred milliliters an hour. According to Dr. Vallaro, this is considered a very conservative figure. At the high end of the range, he estimated that a person would eliminate alcohol at a rate of .02 grams per one hundred milliliters an hour. He testified that, based on years of research conducted since the 1930s, this has been considered a “typical excretion range” and that, in general, a person loses about .015 grams per one hundred milliliters an hour.
Such information included the starting concentration of alcohol, and the time elapsed between the person’s last drink and the taking of the blood sample.
The cases on which the defendant relies to support the proposition that retrograde extrapolation has not been admitted in other jurisdictions are readily distinguishable. In Kempe v. Domestic Corp., 866 F. Supp. 817, 820 (D. Del. 1994), the probative value of retrograde extrapolation evidence was determined to be outweighed by its potential for unfair prejudice where it was impossible to determine how fluid loss due to severe bums and intravenous fluids administered to counteract such fluid loss affected the plaintiff’s blood alcohol level. In McGrew v. Pearlman, 304 Ill. App. 3d 697, 704-706 (1999),
The defendant’s unsupported contention that the judge erroneously instructed the jury on the blood alcohol test is without merit.
Contrary to the defendant’s assertion, the judge did not “[e]schew[] the appropriate constitutional analysis in favor of a bare claim of substantive relevancy.” Rather, he considered the fundamental question whether the defendant had asserted his right to remain silent.
The prosecutor stated: “And when asked where he was drinking, the defendant put his head down and wouldn’t answer.”
The judge properly found, “He didn’t say, T refuse to answer any more, I want a lawyer or I’m not going to talk any further’ and did answer additional questions. . . . [The defendant’s failure to answer the question about where he had been drinking] would not . . . constitute a refusal or an assertion of the right to remain silent.”
