State v. Melissa Robitille, 213 A.3d 437

Background

Melissa Robitille's 13‑year‑old son I.R., with severe holoprosencephaly and diabetes insipidus, died after ethanol was delivered via his G‑tube; autopsy showed BAC 0.146 and cause of death listed holoprosencephaly with contributory acute ethanol toxicity.
On the night of death defendant and her partner Walter Richters disagree about who poured vodka into I.R.’s feeding bag; both admitted at trial to inconsistent prior sworn statements; defendant connected the feeding bag to I.R.’s MIC‑KEY.
Richters pleaded guilty to involuntary manslaughter under a plea agreement and testified for the State; he received a sentence of 4–15 years, split to serve 3 years; the State had earlier amended charges from second‑degree murder to manslaughter.
Robitille was charged (originally second‑degree murder, later reduced), tried by jury, convicted of involuntary manslaughter, and sentenced to 4–12 years; she appealed.
On appeal she raised three main claims: (1) the trial court impermissibly limited cross‑examination of the cooperating witness about his plea exposure (Confrontation Clause); (2) the evidence was insufficient as to causation and criminal negligence; and (3) the court erred by not giving a specific unanimity instruction.

Issues

Issue	Plaintiff's Argument (State)	Defendant's Argument	Held
Whether limiting cross‑examination about the cooperating witness’s precise sentencing exposure violated the Sixth Amendment confrontation right	The State argued it had already informed the jury that Richters received a reduced sentence and that inquiry into precise numerics was unnecessary and prejudicial; the court properly limited cumulative or marginally relevant detail.	Robitille argued the jury needed the specific number of years Richters faced to assess magnitude of motive to lie/ testify.	Court affirmed: exclusion of numeric sentencing detail did not violate Confrontation Clause because defense elicited reduced‑sentence benefit and jury had sufficient facts to assess bias; trial court acted within discretion.
Whether the evidence was sufficient to prove causation (that defendant’s conduct caused I.R.’s death)	State argued facts permitted rational inference that defendant gave more alcohol than she admitted and that, given I.R.’s vulnerabilities, that caused death.	Robitille argued admitted dose (≈1 oz or less) could not explain BAC and there was no proof who supplied any additional alcohol.	Court affirmed: viewing evidence for prosecution, jury could infer defendant administered a fatal amount and thus caused death.
Whether the evidence supported a finding of criminal negligence	State argued defendant, as primary caregiver who understood I.R.’s vulnerabilities and who failed to disclose giving alcohol, grossly deviated from reasonable care.	Robitille argued doctors would not have expected one ounce to be fatal, so risk was unforeseeable and not criminal negligence.	Court affirmed: jury could infer she gave more than the admitted amount and disregarded a risk of death or injury amounting to criminal negligence; foresight of certain death not required.
Whether the trial court erred by not giving a specific unanimity instruction	State argued there was a single charged act (causing death by alcohol ingestion) and no multiple distinct acts requiring election or specific unanimity.	Robitille contended there were two alternative causation theories (she administered lethal dose v. she administered initial dose and Richters later added the fatal dose) so jury needed specific unanimity on which act supported guilt.	Court affirmed: defendant’s theory was a defense, not alternative theories of prosecution; general unanimity instruction sufficed and omission of a specific unanimity charge was not plain error.
