116 N.E.3d 1225
Mass. App. Ct.2018Background
- Defendant Franceschi was indicted for first‑degree murder, armed assault with intent to murder, and leaving the scene; convicted by a jury of voluntary manslaughter and leaving the scene, acquitted of armed assault. Appeal challenges manslaughter conviction and admission of expert testimony.
- Incident facts: dispute at a market the night before; loud noise heard; next morning victim’s car damage noted; while crossing a street, defendant’s vehicle struck and overran the victim, who later died.
- Percipient testimony varied but key agreed facts: victim struck in or near the road’s center (yellow line), vehicle did not meaningfully stop immediately, and defendant drove away after the collision. Daughter testified defendant accelerated, signaled “no,” and failed to brake.
- Forensic evidence: debris/flesh/hair in a cone across lanes and on the yellow line; victim’s feet on the yellow line and head in the northbound lane; vehicle struck under the license plate; accident reconstruction report describing an overrun.
- Commonwealth presented retired officer Laviolette as an accident‑reconstruction expert who identified a mid‑road mark as a shoe “scuff” (point of impact) and opined absence of ABS skid marks showed failure to brake. Defense called a counterexpert who said marks were likely from a snowplow and disputed methods.
Issues
| Issue | Plaintiff's Argument (Commonwealth) | Defendant's Argument (Franceschi) | Held |
|---|---|---|---|
| Sufficiency of evidence (accident vs. intentional killing) | Evidence (witnesses, debris pattern, overrun, flight) permits rational juror to reject accident and find voluntary manslaughter beyond reasonable doubt | Accident fairly raised; Commonwealth failed to disprove accidental hitting because braking/no opportunity to stop not ruled out | Affirmed: viewing evidence in light most favorable to Commonwealth, jury could infer intent/culpability; sufficiency satisfied |
| Admissibility of expert testimony identifying a road mark as a shoe scuff (Lanigan standard) | Laviolette’s training/experience sufficiently qualifies and assists jury; scuff corroborated by evidence path | Laviolette offered no articulated, reliable methodology; identification speculative and could be other sources (e.g., snowplow) | Error to admit scuff‑identification testimony under Lanigan (methodology not shown), but error was nonprejudicial; judgment affirmed |
| Admissibility of expert testimony re: absence of skid marks showing no braking | Laviolette’s observation supported no braking; ABS would leave pulsating marks if braking occurred | Methodology unreliable to conclude ABS braking always leaves pulsating skid marks; jury could infer attempted braking even without marks | Even if Lanigan problem existed, trial testimony acknowledged ABS may not always leave marks; any error nonprejudicial |
| Prejudice from erroneous admission | Erroneous scuff testimony could affect point‑of‑impact issue | Erroneous testimony substantially affected jury’s view of impact location and intent | No prejudice: central issues (whether defendant tried to stop and evidence of overrun, debris, statements, flight) remained and scuff was a side issue |
