Docket No. 67373. Argued April 7, 1983 (Calendar No. 14).—Decided November 22, 1983.
Jeffrey A. Young was convicted by a jury in the Alpena Circuit Court, Philip J. Glennie, J., of first-degree murder as a result of a homicide committed during a burglary. The Court of Appeals, Cavanagh, P.J., and D. E. Holbrook, Jr., and Pierce, JJ., affirmed (Docket No. 44489). The defendant appeals, arguing that the first-degree murder statute in effect at the time of the crime referred to common-law burglary and required proof of all of the elements of common-law burglary, including breaking and entering in the nighttime, to support a conviction of first-degree murder, that evidence of the results of blood analyses should not have been admitted without a showing that the method of analysis used, serological electrophoresis, enjoyed general scientific acceptance, and that evidence of the results of blood analyses should not have been admitted to include the defendant within the class of persons who could have committed the crime.
In an opinion by Justice Brickley, joined by Chief Justice Williams and Justices Kavanagh, Levin, and Ryan, the Supreme Court held:
The statute in effect at the time of the defendant‘s crime required, to support a conviction of first-degree murder for a murder committed during a burglary, proof of the breaking and entering of a dwelling in the nighttime with an intent to commit a felony. Inferences regarding the defendant‘s guilt drawn from blood analyses should not have been admitted into evidence without first determining whether the technique used, serological electrophoresis, has achieved general scientific acceptance for reliability among impartial and disinterested experts. A decision on the admissibility of such analyses to include an accused in the class of possible perpetrators must
- Until 1980, burglary was enumerated in the first-degree murder statute as aggravating conduct which would support a conviction of first-degree murder. To convict a defendant of first-degree murder for a murder committed during a burglary, the people, as in this case, were required to prove the historic common-law elements of burglary, namely, that the defendant broke and entered a dwelling in the nighttime with the intent to commit a felony.
1980 PA 28 substituted breaking and entering of a dwelling for burglary with no distinction as to the time of day at which the crime occurs. Because the victim was killed during the morning hours, the nighttime element was not shown. - Testimony by expert witnesses in criminal cases regarding novel scientific evidence which will aid in identifying a defendant may be admitted so long as it is established that the method of obtaining the evidence has achieved general scientific acceptance among impartial and disinterested experts in its field. In this case, the people‘s expert who testified about blood analyses using the technique of serological electrophoresis to place the defendant in the class of persons who could have committed the crime was not impartial and disinterested, and the record was devoid of impartial and disinterested opinion that the technique is sensitive and specific in measuring what it purports to measure. The case must be remanded to the trial court for an evidentiary hearing to determine whether the technique has achieved general scientific acceptance for reliability among impartial and disinterested experts.
Justice Boyle, concurring in the result, wrote that for purposes of admitting scientific evidence it is necessary to determine that both a scientific technique and the principle or theory which underlies it are generally accepted by members of its field. It is also necessary that the technique be reliable. Acceptance and reliability are not synonymous. The probative value of scientific evidence is dependent on its proven reliability. The testimony of experts whose work is intimately connected with a particular scientific technique should not be precluded in laying the foundation for admission of the technique. Whether an expert witness who is offered to testify with regard to the technique is disinterested and impartial is one of the many elements to be weighed by the trial court in deciding whether the expert is competent. Once the scientific evidence is admitted, the determination of the credibility of such witnesses,
Reversed and remanded.
106 Mich App 323; 308 NW2d 194 (1981) reversed.

OPINION OF THE COURT
1. HOMICIDE — FIRST-DEGREE MURDER — BURGLARY — COMMON LAW.
The enumeration of burglary in the former first-degree murder statute as aggravating conduct which would support a conviction of first-degree murder where a homicide occurred during a burglary required proof of all the elements of common-law burglary including the breaking and entering of a dwelling in the nighttime with the intent to commit a felony (
2. CRIMINAL LAW — EXPERT WITNESSES — SCIENTIFIC EVIDENCE.
Testimony by expert witnesses in criminal cases regarding a novel form of scientific evidence which will aid in identifying a defendant may be admitted so long as it is established that the evidence has achieved general scientific acceptance among impartial and disinterested experts in its field.
CONCURRING OPINION BY BOYLE, J.
3. CRIMINAL LAW — SCIENTIFIC EVIDENCE — EXPERT WITNESSES.
Admission of scientific evidence requires that both a scientific technique used to acquire the evidence and the principle or theory which underlies the technique be generally accepted by members of its field of science and also that it be reliable; expert testimony in establishing acceptance and reliability need not be limited to witnesses who are impartial and disinterested, the credibility of expert witnesses, their interest and bias, being for the trier of fact.

BRICKLEY, J. On December 7, 1978, defendant was convicted by a jury of first-degree murder, as a result of a homicide committed during the perpetration of a burglary.1 Evidence linking defendant to the crime included inculpatory statements by the defendant made to a prosecution witness, fingerprints of the defendant obtained at the scene, and the results of blood analyses which included the defendant in the class of possible perpetrators. There were no eyewitnesses to the crime. There was, however, testimony at trial which established that the decedent was seen alive at 8 a.m. on May 16, 1978. The victim‘s body was discovered in his apartment at approximately 11:30 a.m. that same day. The apartment had been broken into and ransacked.
The Court of Appeals affirmed defendant‘s conviction, 106 Mich App 323; 308 NW2d 194 (1981). We granted leave to appeal, 414 Mich 865 (1982).
Defendant raises three issues on appeal. First, whether burglary in the former first-degree murder statute2 referred to common-law burglary and required proof of all of the elements of the com-
We answer the first question in the affirmative, and the second question in the negative. The answer to the third question must await development of a record by the trial court at the hearing which we order to determine if serological electrophoretic analysis has achieved general scientific acceptance for reliability, Frye v United States, 54 US App DC 46; 293 F 1013 (1923); People v Davis, 343 Mich 348; 72 NW2d 269 (1955), by disinterested and impartial experts, People v Barbara, 400 Mich 352; 255 NW2d 171 (1977); People v Tobey, 401 Mich 141; 257 NW2d 537 (1977).

Defendant begins his argument by declaring that the Legislature has never enacted a burglary statute. It follows, defendant then argues, that the term “burglary” in the first-degree murder statute in effect when this crime was committed must refer to the common-law crime. Citing Cole v People, 37 Mich 544 (1877), defendant avers that the elements of this offense are the breaking and entering of a dwelling house in the nighttime with the intent to commit a felony. Since proofs at trial established that the act occurred during the daytime, defendant concludes that his first-degree murder conviction cannot stand because the people
The people respond by arguing that burglary has been codified in Michigan since 1837. In addition, it is argued, the courts have looked to statutory burglary to determine the sufficiency of allegations in informations charging burglary. The people further argue that statutory burglary contained all the elements of the common-law crime until 1964, when the Legislature deleted the nighttime element from the “burglary-breaking and entering” statute,
Both the people and the defendant rely on People v McDonald, 409 Mich 110; 293 NW2d 588 (1980). In McDonald, the defendant was convicted of first-degree murder during the perpetration or attempted perpetration of a rape. On appeal, the defendant questioned whether a felony-murder conviction could be obtained on the basis of the
“We find the Legislature intended that the repealed carnal knowledge statute define rape for purposes of the first-degree murder statute. The conduct proscribed by the former carnal knowledge statute upon which a first-degree murder conviction was based is also presently prohibited under the criminal sexual conduct act. Consequently, the Legislature did not intend to abrogate such conduct as an aggravating circumstance required for first-degree murder. Rape, as formerly defined under the carnal knowledge law, survives for purposes of prosecution under the first-degree murder statute.” 409 Mich 116.
It was concluded that the rape instructions objected to were properly given by the trial court.
Our analysis of the sexual conduct proscribed, characterized by the term rape, as it existed at the time the first-degree murder statute was last recodified in
Restating the arguments in terms of our analysis in McDonald, defendant would have us look to the last recodification of the first-degree murder statute in 1931 to determine the Legislature‘s understanding of the aggravating conduct required to support a first-degree murder conviction. Defendant‘s argument focuses on the failure of the Legislature to expressly amend that statute as to burglary in the interim between enactment in
In order to better understand our analysis, we first present a brief history of the statutes involved. That will be followed by a more detailed examination of the statutes which prohibited unauthorized entries.

The
In cases which construed these statutes, this Court recognized that the Legislature had created statutory burglary. In Pitcher v People, 16 Mich 142 (1867), Pitcher was charged with statutory burglary. He argued for a limited meaning for the words “dwelling-house“. Justice COOLEY, writing for the Court, noted:
“The statutory definition of burglary in a dwelling-house, is the same as that of the common law; and we must infer that the statute designs simply to provide for the punishment of the common law offense, unless we discover some reason for believing that the legislature employed the definition in some new and restricted sense. No other reason is suggested, except that the words ‘dwelling-house’ are used with restricted meaning in prescribing penalties for other offenses—a reason the force of which must depend upon other considerations.
“If the statute had provided distinct punishments for burglary in the dwelling-house proper, and in the outhouses, etc., used in connection therewith a legislative intent to employ the words ‘dwelling-house’ in a sense not embracing such out-houses, would be very apparent; but it will be perceived, by an examination of the statute, that no such division of the common law offense has been made, and that unless the word ‘dwelling-house’ is used in the sections referred to in their common law sense, many burglaries will not be covered by the statute, and their punishment will consequently not be provided for at all.” 16 Mich 146-147.
Justice COOLEY found that the livestock barn into which the defendant broke and entered in the nighttime with the intent to commit a larceny fell within the meaning of the common-law term “curtilage“. He concluded that the defendant was properly charged with burglary under the statute.
In Cole v People, supra, Cole was charged with statutory breaking and entering of a store. Justice COOLEY, again writing for the Court, compared the charged offense with burglary. This case has been cited by both the people and the defendant for its definition of burglary. It is noteworthy that the
This Court has also looked to the statutory crime to determine the sufficiency of allegations in informations charging burglary. In Harris v People, 44 Mich 305; 6 NW 677 (1880), Harris and Williams were charged with and convicted of the statutory crime of attempted burglary. In affirming their convictions, Justice GRAVES, writing for the Court, noted that burglary is a common-law offense, not a crime created by the Legislature. He further noted that the statutory crime distinguished between simple burglary and aggravated burglary. He cautioned against the conclusion that the addition of aggravating factors to the common-law crime created a new crime:
“The statute does not carve [burglary] into two. It exposes it to different grades of punishment, according as it may or may not be accompanied by the incidents specified in the statute. It may be laid according to the common law, and without referring to the facts on which the imposition of the higher penalty depends; but in such case the punishment cannot exceed the lesser penalty. The accusation will support nothing more. Where the facts are supposed to warrant it, and the higher penalty is contemplated, the crime must be described with the attending facts which justify that penalty.”
Turning to statutory break-ins, Justice GRAVES continued:
“The various breakings resembling burglary which have been declared criminal by the legislature, are distinguishable from the ancient offense of the common law. They owe their definition to the statute, and the statute must be consulted to ascertain their ingredients.
When they are charged they must be set forth in substance, as in the statute, with all descriptive incidents, whether negative or otherwise. Koster v People, 8 Mich 431 (1860); Byrnes v People, 37 Mich 515 (1877).” 44 Mich 307.
See also Hall v People, 43 Mich 417; 5 NW 499 (1880); People v Shaver, 107 Mich 562; 65 NW 538 (1895).
In sum, this Court recognized that the Legislature had codified the common-law crime of burglary in these early statutes. We construed this statutory crime by ascribing to it common-law content. The validity of informations charging burglary was tested against the requirements of the statute. Finally, our recognition of statutory burglary was frequently couched in language which compared the offense (and its common-law analogue) with statutory breakings and enterings.
At all times prior to 1980, the first-degree murder statute required, as an aggravating circumstance, conduct termed burglary. As we have seen, the common-law elements of this crime were adopted as the statutory standard by the Legislature and were consistently construed in their common-law sense by this Court. Thus, at the time the first-degree murder statute was last recodified in
It is an elementary principle of construction that we will assign to common-law terms their common-law meaning unless the Legislature directs otherwise. We have done so with burglary. Pitcher v People, supra; Cole v People, supra; Harris v People, supra. In effect, the people ask us to disregard the plain meaning of the word that the Legislature chose to use and find, instead, that the Legislature meant breaking and entering when it said burglary in
A review of the legislative history of the 1969
This legislative action must be viewed against the historical backdrop of almost 150 years of legislative action distinguishing between the crimes of breaking and entering and burglary.
The argument that the crimes were viewed by the Legislature as interchangeable is similarly suspect. Approximately 150 years of legislative and judicial history suggest the contrary. Even if the people‘s assertion is accepted as true, one might inquire why the Legislature would choose to perpetuate the inconsistency.
We can only conclude that in 1969 the Legislature intended that the crime of burglary, in its common-law sense, be the aggravating circumstance for purposes of the first-degree murder statute.
The people argue that the Legislature has the power to change the common law.
In People v McDonald, supra, we looked to the first-degree murder statute at the time of its enactment to determine the Legislature‘s understanding of the aggravating conduct it deemed necessary to support a first-degree murder conviction. In that case, as here, the Legislature had not expressly amended the first-degree murder statute in the interim between enactment and the commission of the crime in issue. Fundamental to our view is the premise that an express change is necessary for certainty in the conduct proscribed. Such a view precludes our expansion of the holding in McDonald to include implied changes.
It is noteworthy that the people‘s argument assumes, without authority, that the 1964 amendment to
We hold that the term burglary in the first-degree murder statute required that the people prove the historic common-law elements of that offense. It was that conduct, the breaking and entering of a dwelling house in the nighttime with an intent to commit a felony, that the Legislature proscribed as an aggravating circumstance in the first-degree murder statute until it expressly acted to amend the first-degree murder statute in

During the defendant‘s trial, identification evidence obtained by blood analyses using the novel technique of serological electrophoresis was admitted in evidence.6 Defense counsel‘s timely objection to the scientific acceptability of the technique was overruled. The results of the analyses were offered to demonstrate that the defendant was included in the class of persons who could have committed the charged offense. The defendant argues that these results were inadmissible at trial without a prior showing that the technique of serological electrophoresis enjoys general scientific acceptance among impartial and disinterested experts. We agree.
The admissibility of scientific evidence in this state is governed by the so-called Davis-Frye rule. In Frye v United States, 54 US App DC 46, 47; 293 F 1013 (1923), a standard for admissibility of scientific evidence was articulated:
“[W]hile courts will go a long way in admitting expert testimony deduced from a well-recognized scientific principle or discovery, the thing from which the deduction is made must be sufficiently established to have gained general acceptance in the particular field in which it belongs.”
In People v Becker, 300 Mich 562; 2 NW2d 503 (1942), Justice SHARPE, writing for a unanimous Court, concluded that the results of a lie-detector test offered by defendant to prove his innocence were properly ruled inadmissible by the trial court. The opinion noted that no testimony had been offered at trial which revealed “general scientific recognition” of such tests at that time. The opinion concluded:
“Until it is established that reasonable certainty follows from such tests, it would be error to admit in evidence the result thereof.” 300 Mich 566.
In People v Davis, 343 Mich 348; 72 NW2d 269 (1955), the admission of allegedly favorable lie-detector results was again sought by a defendant following an unfavorable trial court ruling. Mindful of the rule in Becker, a trial record was made on the issue, and authorities were cited for the reliability of the results. After restating the rule in Becker, the Court evaluated the material before it in the context of proof of general reliability and acceptability. In a unanimous opinion by Justice BUTZEL, the Court declined to overrule its earlier holding in Becker. The Court identified its concern about the admission at trial of such results before
“The tremendous weight which such tests would necessarily carry in the minds of a jury requires us to be most careful regarding their admission into evidence and we should not do so before its accuracy and general scientific acceptance and standardization are clearly shown.” 343 Mich 372.
In People v Barbara, 400 Mich 352; 255 NW2d 171 (1977), this Court once more considered the issue of the admissibility of lie-detector results. As before, the issue was presented by a defendant who sought the admission of allegedly favorable test results in support of a motion for a new trial following his conviction of extortion. On this issue, a unanimous Court declined the invitation to modify our traditional Davis-Frye rule. Chief Justice WILLIAMS, in an exhaustive and scholarly opinion, interpreted the phrase “general scientific recognition“. He noted that the record was devoid of testimony by “disinterested and impartial experts“. 400 Mich 358. Such experts were later characterized in the following way:
“[T]he witnesses were not disinterested scientists. While one would not want an expert witness without experience or background in the technical field, one would want, where the task was to demonstrate the general scientific acceptability, an acknowledgment of the value of the device and the techniques by disinterested scientists whose livelihood was not intimately connected with it. In addition, the Davis-Frye test requires acceptability by those in certain established scientific disciplines.” 400 Mich 376.
In People v Tobey, 401 Mich 141; 257 NW2d 537 (1977), this Court was confronted with the admissi-
In People v Salvadore Gonzales, 415 Mich 615; 329 NW2d 743 (1982), we last responded to an attack on the Davis-Frye rule. The trial court ruled that hypnotically refreshed testimony was admissible. Applying the Davis-Frye standard, the Court of Appeals reversed. The people appealed. In an opinion written by Justice KAVANAGH, we unanimously concluded that the Court of Appeals was correct in applying the Davis-Frye test. In response to the prosecutor‘s argument that the Davis-Frye rule is applicable only to lie-detector tests, truth serums, drunkenness tests, and narcotics tests, Justice KAVANAGH stated:
“The prosecutor‘s argument that the Frye rule is inapplicable proceeds from an unduly narrow reading of the opinions invoking the Frye rule. The purpose of this rule is to prevent the jury from relying on unproven
and ultimately unsound scientific methods.” 415 Mich 623.
In the instant case, and despite our invariant and unanimous application of the Davis-Frye rule to the admissibility of novel scientific evidence, the trial court did not conduct a Davis-Frye hearing before the results of serological electrophoresis testing were admitted into evidence. That was error.7
Before this Court, the people argue variously that the technique of serological electrophoresis is accurate and reliable in scientific literature, has the support of disinterested and impartial experts, and has been accepted in other states. These assertions would be persuasive of general scientific acceptance of the technique‘s reliability for identification if they were accompanied by a record that addressed that point. They do not. The limited record information we have before us on which to form an opinion about the reliability of the technique comes from the testimony of the people‘s expert witness, Mark Stolorow, a Michigan State Police employee and co-developer of the technique, who testified that he devoted approximately 90% of his work time to using the technique on bloodstain samples received at the State Police Crime Laboratory. We think this to be insufficient to
The people argue that the Davis-Frye rule should be abolished because it hinders early courtroom use of technological advances in the rapidly developing discipline of forensic science. In addition, it is argued, the adoption of MRE 702 by this Court substantially undercuts the necessity for the Davis-Frye rule because the party opposing admissibility will be able to challenge general scientific acceptance during the proponent‘s qualification of its expert witness.
We answered the people‘s technological advance argument in People v Salvadore Gonzales, supra, where we stated that the purpose of the Davis-Frye rule “is to prevent the jury from relying on unproven and ultimately unsound scientific methods“. We approve the reasoning of the court in United States v Brown, 557 F2d 541, 556 (CA 6, 1977):
“A courtroom is not a research laboratory. The fate of a defendant in a criminal prosecution should not hang on his ability to successfully rebut scientific evidence which bears an ‘aura of special reliability and trustworthiness,’ although, in reality the witness is testifying on the basis of an unproved hypothesis in an isolated experiment which has yet to gain general acceptance in its field.”
We stress that the issue is not whether this test, or any test, is an appropriate scientific undertaking. It is whether the inferences to be drawn from the test results are admissible. Inferences are admissible if they are generally accepted by impar-
The argument of the superfluity of the Davis-Frye rule in the light of
“If the court determines that recognized scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise.” (Emphasis supplied.)
At issue in this case is whether identification evidence derived from serological electrophoretic analysis of blood has achieved general scientific acceptance as being reliable. The Davis-Frye standard is the means by which the court can determine that the novel evidence offered for admission here enjoys such recognition.
Finally, the prosecutor argues that a Davis-Frye error here, if any, was harmless beyond a reasonable doubt because of the other evidence of defendant‘s guilt adduced at trial. In the light of the hearing which we order, we conclude that this argument is premature and need not be addressed at this time.
We hold that the admissibility of novel scientific evidence is governed by the Davis-Frye standard. Such evidence must have achieved general scientific acceptance among impartial and disinterested experts. In this case, we are unable to determine from the record before us whether blood analysis identification evidence from the technique of serological electrophoresis is competent evidence. A Davis-Frye hearing should have been held. We remand this case to the trial court for an eviden-

I concur in the result. I write separately because although I agree with the majority that the Davis-Frye1 test is applicable to the type of scientific evidence which was admitted and that this case must be remanded so that a proper foundation may be laid, I do not agree with the majority‘s application of Davis-Frye nor its interpretation of Barbara-Tobey.2
A court applying Davis-Frye must determine whether both the technique and the underlying principle or theory have been “generally accepted” by members of the field.
“Resolving this issue involves focusing on the distinction between the validity of a technique and the validity of its underlying theory. One could accept, for instance, the validity of the premise underlying voiceprint identification—voice uniqueness—but still reject the validity of the voiceprint technique. Similarly, the
underlying psychological and physiological principles of polygraph evidence could be acknowledged without endorsing the proposition that a polygraph examiner can detect deception by means of the polygraph technique. “A novel forensic technique, however, may involve either the new application of a well-established theory or the application of a new theory. In the latter case, the theory can be validated only empirically or inferentially, not deductively. In other words, the successful application of the technique proves the validity of the underlying theory or principle. In terms of the Frye test, if the technique is generally accepted, then the theory must be valid although not fully understood or explainable.”3
The court must also determine whether the technique is reliable. General acceptability and reliability are not synonymous. To equate general acceptance with reliability would present “an abandonment of Frye because the reliability of a scientific technique could be established notwithstanding its lack of general acceptance in the scientific community“.4 The probative value of scientific evidence is dependent upon its proven reliability. If a technique is not reliable, evidence derived from that technique is not relevant.5
The theory of serological electrophoresis is recognized in the scientific community and has been applied in a wide variety of situations.6 The concern herein is with whether application of this principle to genetic marker phenotyping of dried blood samples has achieved general scientific ac-
II
I would not interpret Barbara-Tobey as precluding the testimony of experts whose work is intimately connected with a particular scientific technique. Whether an expert witness is disinterested and impartial is one of the many elements to be weighed by the trial judge in deciding whether the expert is competent. Aside from this preliminary and limited inquiry, determination of interest and bias should be an issue for jury determination, no less so in the evaluation of expert witness testimony than with that of the testimony of any other witness.
I agree that the testimony of technicians alone may be an insufficient basis on which to conclude that general scientific recognition has been established. This Court‘s evaluation of the record evidence in both Barbara and Tobey was that the testimony offered did not establish a clear consensus by the general scientific community. For example, in Barbara, fn 2 supra, p 358, “all submitted testimony was given by polygraph operators, polygraph teachers or others connected with the use of polygraphs“. This Court found that “acceptance by scientists rather than polygraph operators has not been general and widespread“. Id., p 376.
To construe Barbara-Tobey to require that the Davis-Frye foundation be established by one who is disinterested and impartial although otherwise competent is inconsistent with the rationale for the Davis-Frye rule which is that scientific expert testimony tends to carry undue weight in the
Scientific advances may originate from altruistic or materialistic motives, or any combination thereof. These are issues relating to the probative value of the witnesses’ testimony, which for two centuries have been regarded as within the competence of jurors. Unless we are to conclude that jurors are somehow less capable of evaluating the bias and interest of those in the fields of science and technology than they are of assessing the weight and credibility of the testimony of physicians or engineers, there is no justification for the Barbara-Tobey limitation.
A broad reading of Barbara-Tobey also imposes an unnecessary barrier to the introduction of probative evidence, as illustrated by the present case. The key expert witness at trial was Mark Stolorow, then employed by the Michigan State Police as a forensic serologist. Mr. Stolorow is a co-developer of the technique and testified that he devoted approximately 90% of his work time to using the technique on bloodstain samples received at the State Police Crime Laboratory. Clearly, Mr. Stolorow appears to be a competent expert, yet strict application of Barbara-Tobey would foreclose his testimony. Impartiality and disinterestedness are
Genetic marker phenotyping of bloodstains is a procedure only routinely used in police case work.7 It is not a procedure which is commonly used in other scientific communities because the need for the resultant information is not present. Whether the testimony of a forensic scientist meets the Davis-Frye requirement is a separate and distinct issue from whether a forensic scientist is a competent witness. To prevent the forensic scientists who develop and use a particular procedure from testifying is to needlessly limit the factfinder‘s consideration of otherwise relevant and probative evidence.
III
Finally, as a separate consideration from the Davis-Frye issue, defendant claims that it was error to admit expert testimony of blood analysis which included defendant within the category of possible perpetrators. Defendant claims that such evidence was more prejudicial than probative because defendant was not specifically identified by such evidence.
The admission of such evidence is a relevancy question to be based on the facts of each case, i.e., whether, as interpreted, the results are relevant to the issues in dispute. If the evidence presented places the defendant in a class of possible perpe-
