The accused, Michael Allen, was charged with assault causing bodily harm to his six-month-old stepson, Hayden Ouellette-Meissner, after the infant sustained bilateral humeral fractures.
The defense admitted the injuries but disputed causation, arguing they were accidental.
The court heard conflicting expert medical opinions from a pediatrician specializing in child abuse (Dr. Nolan) and a pediatric orthopedic surgeon (Dr. Wedge).
Dr. Nolan found the injuries highly suspicious for inflicted injury and inconsistent with the proposed accidental mechanism.
Dr. Wedge suggested an accidental mechanism involving the infant's arms getting caught in couch cushions during a fall, though his testimony was found less persuasive and inconsistent.
The court, applying the principles of R. v. W.(D.) and R. v. Griffin, found that while the case was highly suspicious, the Crown had not proven beyond a reasonable doubt that the accused caused the fractures, leading to an acquittal.
