The defendant, Eric C. Woods, appeals from convictions on two separate counts of vehicular homicide by negligent operation, 1 G. L. c. 90, § 24G (6) (1990 ed.), and one count of operating a motor vehicle after the suspension of a license pursuant to G. L. c. 90, § 24N (1990 ed.). We transferred this case on our own motion, and we now affirm the convictions.
The defendant’s convictions stem from a motor vehicle accident in which two people were killed. The accident occurred at 12:52 a.m. on November 17, 1989, in Dudley. After drinking at a local establishment, Jonathan Edgerly, Patrick Donnelly, Todd Gillis, and the defendant entered a Ford Bronco motor vehicle belonging to the defendant’s father. Not long after that, the motor vehicle careened off the road and struck a tree. When help arrived, they found Edgerly and Donnelly dead in the back seat of the vehicle. In the front seat, both Gillis and Woods were seriously injured. They were taken by police and emergency personnel to a hos *345 pital for treatment of their injuries. At the hospital, Woods disclosed to the emergency personnel that he had drunk some beer earlier in the evening. His blood alcohol level was tested, and it registered .03 several hours after the incident. 2
Woods was charged in the District Court with (1) operating under the influence of alcohol in violation of G. L. c. 90, § 24; (2) two separate counts of vehicular homicide while under the influence of alcohol under G. L. c. 90, § 24G; (3) two separate counts of vehicular homicide by negligent operation in violation of G. L. c. 90, § 24G (a); (4) operating to endanger in violation of G. L. c. 90, § 24; and (5) operating after the suspension of his license pursuant to G. L. c. 90, § 24N. After opting for a bench trial, Woods was found guilty only on the counts in (3) and (5), above. As to the counts in (1) and (2), Woods was found not guilty. The remaining charge, operating to endanger, was dismissed as duplicative.
The defendant then exercised his right to trial de nova pursuant to G. L. c. 218, § 26A (1990 ed.). He filed two motions in limine. The first requested that the Commonwealth be precluded from offering any evidence pertaining to his alcohol consumption on the ground that he had been acquitted of all alcohol-related charges at the bench trial. The second motion requested that the Commonwealth be precluded from offering any evidence regarding ownership of the Ford Bronco by the defendant’s father on the ground that such evidence would be unfairly prejudicial to the defendant on the issue of who was operating the vehicle at the time of the accident. The trial judge denied both motions. A jury of six found the defendant guilty on the same counts. He filed a timely appeal.
The defendant alleges several errors in his appeal. We shall address them seriatim.
*346
1.
Double jeopardy.
The Fifth Amendment to the United States Constitution prohibits the Federal government from subjecting a defendant to more than one prosecution for the same offense.
3
This prohibition was extended to the State governments through the due process clause of the Fourteenth Amendment.
Benton
v.
Maryland,
*347
We conclude that the defendant has misinterpreted the holding in
Grady
and misapplied it to the facts of his case. Essentially, the defendant interprets
Grady
as precluding from use in a subsequent trial any evidence that was used to support the prosecution’s case in the original trial. This interpretation, however, finds no support in the language of the
Grady
decision. The
Grady
Court explicitly refused to adopt an “actual evidence” or a “same evidence” test for double jeopardy.
Id.
at 521.

Instead, the Court reaffirmed its previous position that “the presentation of specific evidence in one trial does not forever prevent the government from introducing that same evidence in a subsequent proceeding.”
Id.
at 521-522, citing
Dowling
v.
United
States,
In Grady, the defendant pleaded guilty to driving while intoxicated and failure to keep right of the median strip. Id. at 512-513. In a subsequent prosecution, the State sought to use proof of this same conduct, driving while intoxicated and failure to keep right of the median strip, to prove vehicular homicide by operation of a motor vehicle in a criminally negligent and reckless manner. Id. at 514. The prosecution ad *348 mitted that it would prove “the entirety of the conduct for which [the defendant] was convicted ... to establish the essential elements of the homicide and assault offenses.” Id. at 523. In other words, the prosecution in the second trial attempted to use the same evidence from the first trial to prove the same conduct. Because the defendant in Grady had already been prosecuted for the conduct offered for proof of the subsequent charges, the Court held that the second prosecution was barred by the double jeopardy clause. Id.
In fashioning its decision, the
Grady
Court expressly adopted the dicta of an earlier opinion,
Illinois
v. Vitale,
In
United States
v.
Felix,
We read the
Grady
opinion as redefining the phrase “same offense” in the double jeopardy clause.
Grady
substitutes for “same offense” the phrase “conduct that constitutes an offense for which the defendant has already been prosecuted,”
supra
at 510. This redefinition does not make
Grady
a “same transaction” test, rejected by this court in
Commonwealth
v.
*350
Gallarelli,
Woods’ acquittal in his first trial resolved only one factual issue: he was not driving while under the influence of alcohol.
9
In the second trial, the Commonwealth used the same evidence to prove that the defendant had been negligent. The crucial point for
Grady
purposes , is that a reasonable jury could (and did) find the defendant negligent though not intoxicated. The two offenses were not the same. “Two offenses are not the ‘same’ within the meaning of the double jeopardy clause merely because they stem from the same conduct.”
Costarelli
v.
Commonwealth,
When viewed in light of the Commonwealth’s two-tier trial system, see generally
Lydon
v.
Commonwealth,
First of all, in our two-tier trial system, a defendant convicted of charges in the first-tier trial remains in “continuing jeopardy” until judgment is final in the second-tier trial.

v.
Lydon, supra
at 308. Original jeopardy continues because the defendant may appeal any conviction automatically and need not plead error. G. L. c. 218, § 26A.
Justices of Boston Mun. Court
v.
Lydon, supra
at 304-305. Trial de nova is a unified process where, at the defendant’s request, the previous judgment is “wiped out,” and the case begins anew.
Mann
v.
Commonwealth,
Second, because the defendant remained in continuing jeopardy, he faced only one prosecution. Double jeopardy intervenes to protect defendants from facing multiple prosecutions for the same offense. “[T]he State with all its resources and power should not be allowed to make repeated attempts to convict an individual for an alleged offense, thereby subjecting him to embarrassment, expense and ordeal and compelling him to live in a continuing state of anxiety and insecurity, as well as enhancing the possibility that even though innocent he may be found guilty.”
Costarelli, supra
at 681, quoting
Green
v.
United States,
For these reasons, we hold that the defendant’s double jeopardy claim fails.
2. Collateral estoppel. The defendant argues that because he was found not guilty of driving while under the influence, the Commonwealth was precluded on collateral estoppel grounds from introducing in the second trial any evidence regarding his consumption of alcohol. He claims that the trial judge erred in denying his motion to exclude such evidence. For the reasons stated above, this claim is without merit.
The doctrine of collateral estoppel operates in criminal proceedings as part of the guarantee against double jeopardy.
Commonwealth
v.
Scala,
We hold that the trial judge did not err in denying the defendant’s motion to exclude evidence on collateral estoppel grounds.
3. Insufficient evidence. The defendant asserts that the trial judge erred in failing to allow his motion for a required finding of not guilty based on insufficient evidence that the defendant was the operator of the motor vehicle at the time of the accident. After reviewing the record, we conclude that there was ample evidence to support a jury verdict.
A motion for a required finding of not guilty will be allowed only where “the evidence is insufficient as a matter of law to sustain a conviction on the charge.” Mass. R. Crim. P. 25 (a),
4.
Rulings on evidence.
The defendant claims the trial judge committed reversible error when ruling on three evidentiary matters. First, he claims that evidence concerning the possession of marihuana by a person who was also found in the front seat of the motor vehicle was improperly excluded. He argues that such evidence is probative of who was operating the motor vehicle at the time of the accident. This argument presumes that from the mere evidence of possession the jury could have inferred that (1) the person ingested the marihuana; (2) the marihuana produced a degradation of his motor skills; (3) such a degradation of motor skills could have caused an accident similar to the one at issue here, and, therefore, (4) that person might have been driving. Such a chain of inference is tenuous at best and, without any supporting evidence, approaches impermissible speculation at worst. It opens up collateral issues regarding the possession and use of marihuana among the passengers as well as stirring up prejudice. It is well within the trial judge’s discretion to determine if the prejudicial effect of such evidence outweighs its probative value.
Commonwealth
v.
D’Agostino,
*356
Second, the defendant claims the trial judge erroneously denied his motion to exclude evidence concerning the identity of the motor vehicle’s owner. He argues that such evidence was not probative of who was driving and was, in fact, unduly prejudicial. The defendant, however, fails to describe specifically what prejudice resulted from the admission of this evidence. He states that the jury could infer from this evidence that the defendant operated the motor vehicle because his father owned it. This inference, he claims, is impermissible. What the defendant has done is to imply that the probative aspect of the evidence is actually the unfair prejudicial element. We note that evidence is not prejudicial simply because it harms the defendant’s case. Any evidence which “throws light” on an issue is properly admitted.
Commonwealth
v.
Palladino,
Third, the defendant claims that the trial judge should have excluded evidence that the arresting officer handed the defendant’s parents a citation for the defendant as impermissible opinion evidence, c and that his failure to do so shifted the burden of proof in violation of due process principles. We note, first of all, that the police were required to establish that a citation for the accident was given to the defendant or sent to his residence for the charge of operation after the suspension of a license, G. L. c. 90C, § 2 (Supp: 1991), although the vehicular homicide charges carried no such requirement. Of course, the evidence could be used for *357 purposes beyond the intent of the statute which might prove unfairly prejudicial to a defendant. In this case, however, the record clearly shows that the evidence regarding the citation was strictly circumscribed before and after the defense counsel’s objection. No mention was made of the charges listed on the citation, and any prejudice involved in identifying who received the citation amounted to harmless error in light of the other evidence presented. We conclude, therefore, that there was no prejudicial error.
5. Prosecutorial misconduct. The defendant claims that the judge erred in not granting him a mistrial after the prosecutor made appeals to the sympathy of the jury. The defendant cites three specific incidents. After reviewing these incidents, we conclude that the defendant did not suffer undue prejudice, and therefore a mistrial was not warranted.
The defendant draws this court’s attention first to the prosecution’s closing argument. The prosecutor stated that the defendant was more “fortunate” than the other passengers who died in the accident. Although this statement surely evoked an emotional reaction, it did not require a mistrial. It is well within the trial judge’s discretion to deny a mistrial on the ground of prosecutorial misconduct and to rely on appropriate curative instructions even in the case of intentional misstatements by the prosecution.
Commonwealth
v.
Charles,
Next, the defendant claims error in the prosecutor’s argument that his recollection was that at the hospital the defendant asked only about “my truck” and not about the other passengers. Closing arguments are reviewed in light of jury instructions and the evidence presented during trial. Commonwealth v. Lamrini, 392 Mass. 427, 432 (1984). In this case, the issue of who was driving at the time of the accident was hotly contested. Defendant’s statements concerning “my truck” were highly probative of that issue. Thus, the argument was not made solely to stir up resentment against the defendant. With regard to any prejudicial effect, the judge instructed the jury not to allow sympathy to control their decision and to view the closing statements as arguments but not evidence. Since the prosecutor was again relying on the evidence presented at trial and not his imagination, the jury instructions adequately responded to any injury the defendant may have suffered from this argument.
Lastly, the defendant strongly objects to the identification of the victims’ parents in the courtroom. We agree with the defendant that such tactics which appeal solely to the sympathy of the jury should not be condoned. In the context of this trial, however, the defendant was not unfairly prejudiced. We note that defense counsel asked a witness on cross-examination to point out the defendant’s parents, who were sitting in the courtroom. Furthermore, both the prosecution and defense counsel referred to the parents and families of the passengers and the defendant several times throughout the trial. Therefore, there was no error.
When mitigating factors were present at trial, and curative instructions were read to the jury, we defer to the judgment of the trial judge, who was in the better position to determine the prejudice to the defendant in the context of the trial.
Commonwealth
v.
Martino,
For these reasons, we conclude that there were no prejudicial errors at trial, and, therefore, we affirm the convictions.
Judgments affirmed.
Notes
General Laws c. 90, § 24G (A) (1990 ed.), reads in part: “Whoever, upon any way or in any place to which the public has a right of access or upon any way or in any place to which members of the public have access as invitees or licensees, operates a motor vehicle recklessly or negligently so that the lives or safety of the public might be endangered and by any such operation causes the death of another person, shall be guilty of homicide by a motor vehicle and shall be punished by imprisonment in a jail or house of correction for not less than thirty days nor more than two and one-half years, or by a fine of not less than three hundred nor more than three thousand dollars, or both.”
We note that a blood alcohol level at or below five one-hundredths (.05) entitles the defendant to a presumption that he was not under the influence of intoxicating liquor. G. L. c. 90, § 24 (1) (e) (1990 ed.).
The double jeopardy clause of the Fifth Amendment to the United States Constitution provides, “[N]or shall any person be subject for the same offense to be twice put in jeopardy of life or limb.”
The test effectuates three protections embodied in the double jeopardy clause: “It protects against a second prosecution for the same offense after acquittal. It protects against a second prosecution for the same offense after conviction. And it protects against multiple punishments for the same offense.”
Grady
v.
Corbin,
Double jeopardy protection applies equally to bench and jury trials.
United States
v.
Morrison,
The
Grady
Court also noted that the older
Blockburger
test for double jeopardy, see
Blockburger
v.
United States,
The
Blockburger
test is identical to the so-called
Morey
test applied by this court in double jeopardy cases to distinguish offenses under criminal statutes which do not address the question of consecutive punishments.
Morey
v.
Commonwealth,
With regard to the conspiracy charge, the court held that a substantive crime and a conspiracy to commit that crime are not the “same offense” for double jeopardy purposes.
United States
v.
Felix,
Because the defendant was acquitted on the issue of driving while under the influence of alcohol, he was entitled to a jury instruction on that point. After reviewing the trial judge’s instructions, we believe they adequately protected the defendant’s rights in this regard.
In his first trial Woods was acquitted of vehicular homicide while driving under the influence of alcohol but convicted of what was essentially the lesser included offense of vehicular homicide by negligent operation. Both charges require proof of negligent operation, but vehicular homicide while under the influence requires, additionally, proof of intoxication. G. L. c. 90, § 24G. Woods, therefore, was never acquitted of the lesser included charge. Unlike Grady, who in his second prosecution faced a new, more severe charge based wholly upon his conviction of a lesser included charge, Woods faced “continuing jeopardy” with regard to the lesser included charge, see infra this section, and never again faced prosecution for the greater offense.
The United States Supreme Court has repeatedly upheld the trial de nova system against double jeopardy claims. See
Justices of Boston Mun.
*353
Court v.
Lydon,
We note here that the defendant cites in his brief an incorrect test for the admissibility of evidence. Even evidence that is barely probative may be, nonetheless, relevant and therefore admissible unless outweighed by prejudice to the defendant. See
Green
v.
Richmond,
