Summary
The Massachusetts Supreme Judicial Court held that sufficient evidence supported the defendant’s conviction for negligent vehicular homicide, so double jeopardy did not bar retrial. The court nevertheless affirmed the order granting a new trial because the Commonwealth failed to disclose material exculpatory evidence concerning expert opinions about damage to the vehicle’s windshield. The court also concluded that the prosecutor’s conduct, including improper closing-argument statements, did not warrant dismissal of the charges.

Questions Presented
- Whether the evidence at the original trial was legally sufficient to support convictions for operating a motor vehicle negligently and causing death, such that retrial would not violate double jeopardy.
- Whether the Commonwealth's delayed disclosure of material exculpatory evidence required dismissal of the charge rather than a new trial.
- Whether the prosecutor's closing argument and alleged failure to disclose or investigate evidence constituted misconduct so egregious that dismissal was required and retrial barred.
Holdings
- The evidence, viewed in the light most favorable to the Commonwealth, was sufficient for a rational jury to find beyond a reasonable doubt that the defendant operated the cruiser negligently on a public way and caused the victim's death. Because the original evidence was legally sufficient, retrial was not barred by double jeopardy.
- The accident-reconstruction expert's opinion concerning the cause of the windshield damage and the absence of evidence that the defendant's head struck the windshield was material and exculpatory; its nondisclosure required a new trial.
- The prosecutor's closing argument included improper statements, but the conduct was not sufficiently egregious to require dismissal. The record did not show that the Commonwealth intended to provoke a mistrial, that a fair retrial was impossible, or that dismissal was necessary to deter comparable misconduct.
Key quotations
“Under the familiar Latimore standard, the evidence is sufficient to reach the jury and a motion for a required finding of not guilty is properly denied if the evidence, viewed in the light most favorable to the Commonwealth and drawing all inferences in favor of the Commonwealth, would permit a rational jury to find each essential element of the crime beyond a reasonable doubt.” (453 Mass. at 660)
“We agree with the judge who conducted the hearing on the defendant's motion for a new trial that Ryan's opinion was material and exculpatory.” (453 Mass. at 664)
“We have delineated limited circumstances for dismissing a complaint due to prosecutorial misconduct” (453 Mass. at 666)
“There was sufficient evidence introduced at the defendant's trial for a rational jury to have found beyond a reasonable doubt that the defendant was guilty of motor vehicle homicide by negligent operation.” (453 Mass. at 668)
Factual background
The defendant, a Beverly police officer, was driving a police cruiser when it accelerated up Cabot Street and struck a parked vehicle, killing its occupant. Accident-reconstruction evidence showed that the cruiser traveled approximately 474 to 526 feet, reached approximately fifty-two to fifty-five miles per hour in a thirty-mile-per-hour zone, and had its accelerator nearly fully depressed before impact. The defense asserted that the defendant suffered a seizure, while the Commonwealth argued that he negligently operated the vehicle. After trial, the Commonwealth disclosed that its accident-reconstruction expert believed the windshield damage was most likely caused by the crash and found no evidence that the defendant's head had struck the windshield; the trial judge found that this information was material and exculpatory.
Procedural history
A District Court jury convicted the defendant of negligent motor vehicle homicide. The trial judge allowed the defendant's motion for a new trial after finding that the Commonwealth had failed to disclose material exculpatory evidence concerning the accident reconstruction expert's opinion about windshield damage. The Supreme Judicial Court affirmed the order allowing a new trial, holding that the evidence was sufficient to support the conviction and that the alleged prosecutorial misconduct did not warrant dismissal or bar retrial.
Remand instructions
The defendant may be retried. The order allowing the motion for a new trial was affirmed; dismissal was not required.
