Summary
The Vermont Supreme Court reviews Tristan Cameron’s conviction for grossly negligent operation of a motor vehicle resulting in death. The court holds that the evidence was sufficient to submit the charge to the jury, but reverses and remands for a new trial because marijuana-use evidence was admitted without expert testimony linking the use to the alleged negligent operation. The court also declines to review unpreserved Miranda, parental-consultation, and voluntariness claims concerning Cameron’s statement to police.

Questions Presented
- Whether the evidence was sufficient to allow a jury to find grossly negligent operation of a motor vehicle resulting in death.
- Whether evidence of Cameron's marijuana use was relevant and admissible under Vermont Rules of Evidence 401 and 403 absent expert testimony connecting the use to his operation of the vehicle.
- Whether Cameron's unpreserved claims concerning Miranda warnings, consultation with a parent, and voluntariness of his marijuana-use statement could be reviewed on appeal.
- Whether presubmission discussions among jurors required a new trial.
- Whether the trial court's reasonable-doubt instruction constituted structural error.
Holdings
- The State presented sufficient evidence to create a legitimate question for jury deliberation and to support a finding that Cameron operated grossly negligently, even if he was within the posted speed limit.
- Cameron's claims that the statement should have been suppressed for lack of Miranda warnings, lack of an opportunity to consult a parent, or involuntariness were waived and not preserved because trial counsel did not file a suppression motion and expressly stated that the objection was not constitutional.
- Evidence of Cameron's marijuana use was inadmissible under Rules 401 and 403, absent expert testimony connecting the marijuana use to whether he operated his vehicle in a grossly negligent manner.
- State v. Devine is overruled to the extent it is inconsistent with State v. Rifkin on the foundation required for marijuana-use evidence offered to establish negligent or grossly negligent vehicle operation.
Key quotations
“But because, absent expert testimony, the jury was left to speculate that the State’s evidence provided the necessary link between defendant’s marijuana use and the grossly negligent operation charge, we reverse and remand for a new trial on the second issue.” (¶ 1)
“Under Rifkin, the evidence of marijuana usage had no probative value absent expert testimony relating the marijuana usage to whether defendant was grossly negligent in his operation of his vehicle at the time of the accident.” (¶ 28)
“This is not a case where we can conclude that the improper evidence could not have contributed to the verdict.” (¶ 29)
Factual background
Seventeen-year-old Tristan Cameron was driving north on a freshly graveled, curving, partly blind dirt road when he encountered three southbound farm trucks. He steered toward the edge of the road, overcorrected, lost control, and collided with the second truck; his passenger died the next day from crash injuries. Evidence indicated that Cameron was traveling at a speed that prevented him from controlling the vehicle around the blind corner, and he had admitted that he had fallen asleep. The State also introduced evidence that Cameron had used marijuana earlier that morning, but presented no expert testimony linking that use to his driving or gross negligence.
Procedural history
Cameron was charged under 23 V.S.A. § 1091(b) after a motor-vehicle collision killed his passenger. Following a three-day jury trial, he was convicted. The trial court denied his motions for judgment of acquittal and admitted testimony concerning his marijuana use. The Vermont Supreme Court affirmed the denial of acquittal but reversed the conviction because the marijuana-use evidence was admitted without expert testimony connecting the use to grossly negligent operation, and remanded for a new trial.
Remand instructions
The conviction is reversed and the case is remanded for a new trial. On retrial, marijuana-use evidence may not be admitted to connect marijuana use with grossly negligent operation without the required expert foundation.
