BURLINGTON — A Vermont judge has rejected a bid for a new trial for the man convicted in May of five counts of second-degree murder in a wrong-way crash that killed five teenagers.

Judge Kevin Griffin issued his 37-page decision Monday in Chittenden County Superior criminal court in Burlington.

The case against Steven Bourgoin, formerly of Williston, now moves to a sentencing hearing set for Aug. 26.

“We are obviously disappointed with the decision and plan on raising many of these same issues on appeal after sentencing,” Robert Katims, Bourgoin’s attorney, said in a statement about the judge’s ruling denying the request for a new trial.

Chittenden County State’s Attorney Sarah George could not immediately be reached Monday for comment.

Bourgoin faces up to 20 years to life in prison on each of the five counts of second-degree murder in the deaths of the teenagers in the crash that took place late on the night of Oct. 8, 2016, on Interstate 89 in Willison.

In returning its guilty verdicts in May, the jury did not accept the defense’s contention that Bourgoin was insane at the time of the crash.

Katims had raised several points in his motion for a new trial, including that the prosecution presented “sparse evidence” about Bourgoin’s mental state in the hours leading up to the hours.

George countered that the evidence “sufficiently and fairly” supported the jury’s guilty verdicts.

Griffin rejected all of Katims arguments in his Monday ruling.

The judge wrote that “taking the evidence in the light most favorable to the State and excluding modifying evidence, a reasonable jury would be justified in finding Defendant guilty beyond a reasonable doubt.”

Griffin wrote that Bourgoin’s defense did not meet the burden as to the insanity defense by a preponderance of the evidence.

The judge denied the motion for acquittal on the grounds that prosecutors failed to rebut evidence supporting a defense of insanity.

During the trial, Katims argued to the jury that his client was insane at the time of the crash, pointing to defense witnesses who testified the 38-year-old believed he was on a top-secret government mission, getting messages through devices, such as his computer and his pickup truck’s radio.

“He’s confused, he’s psychotic, he’s delusional,” Katims said of Bourgoin in his closing argument to the jury.

Prosecutors argued that Bourgoin’s actions were intentional, fueled by anger over his financial struggles and a child custody dispute with his ex-girlfriend.

Killed in the crash were Eli Brookens, 16, of Waterbury; Janie Chase Cozzi, 15, of Fayston; Liam Hale, 16, of Fayston; and Mary Harris and Cyrus Zschau, both 16, and from Moretown. Four of the teenagers attended Harwood Union High School in Duxbury. Cozzi attended Kimball Union Academy in Meriden.

In addition to denying the motion for a new trial Monday, Judge Griffin said a motion filed by the defense under seal also seeking a new trial would be unsealed and become part of the case file.

It was not immediately known if that filing had been unsealed by the court early Monday afternoon.
