Jennifer Gaskin’s manslaughter conviction for the death of her infant son nearly 25 years ago has been overturned by the Ontario Court of Appeal, marking a significant development in the reassessment of shaken baby syndrome cases in the province.
Gaskin, 51, was convicted in 2002 for the 1999 death of her son Joseph, who was found to have suffered fatal head injuries consistent with repeated shaking. At the time, the diagnosis of shaken baby syndrome was widely accepted based on the presence of the so-called “triad” of brain swelling, retinal hemorrhages, and tissue injuries observed during autopsy, even in the absence of external trauma. However, the scientific foundation for this diagnosis has since been challenged, leading to scrutiny of many similar convictions.
The appeal hearing took place on Tuesday in Toronto with Gaskin’s mother and daughter—who was removed from Gaskin’s care after her arrest and only recently reunited with her—present in the courtroom. Both the Crown and the defense jointly recommended that the court enter an acquittal, acknowledging that the original conviction was based on now-discredited scientific evidence.
The appeals panel, consisting of Justices Sally Gomery, Peter Lauwers, and Renee Pomerance, agreed and ruled that the conviction was “unsustainable.” Justice Lauwers noted that Gaskin’s case was part of a broader pattern of wrongful convictions linked to unreliable expert testimony concerning shaken baby syndrome, echoing concerns raised following investigations into forensic pathologist Charles Smith. Smith, who worked at Toronto’s Hospital for Sick Children, was previously found to have provided flawed expert opinions in multiple child death cases dating back to the 1980s.
Joseph Gaskin was born prematurely at nine and a half weeks and spent two months in hospital before returning home in mid-June 1999. Two days after a health clinic visit for vomiting concerns, the infant stopped breathing and later died. Autopsies conducted by a surgical pathologist in Thunder Bay and a neuropathologist at the Hospital for Sick Children attributed his death to repeated shaking over about two weeks, a claim Ms. Gaskin always denied.
New evidence submitted at the appeal included reports from a forensic neuropathologist, a biomechanical engineer, and a forensic pathologist, alongside findings from an Ontario government expert committee reviewing shaken baby deaths. These reports concluded that natural causes could not be ruled out as factors in Joseph’s cardiorespiratory arrest, and some injuries observed may have resulted from the autopsy process itself. The panel also pointed out that the scope of medical testing available at the time was insufficient compared to current standards.
Crown attorney Elise Nakelsky acknowledged the hardship Gaskin endured due to her wrongful conviction. James Lockyer, Gaskin’s lawyer and co-founder of Innocence Canada, described the decision as a “giant leap forward” that might signal the end of shaken baby syndrome as a prosecutorial basis in Ontario. Innocence Canada is actively seeking to overturn multiple other cases involving similar diagnoses.
Gaskin, who now resides in Eastern Ontario and works as a restaurant hostess, expressed relief and gratitude following the court’s decision. She highlighted the emotional toll the conviction had taken on her and the hope that clearing her name would allow her to rebuild relationships with her children. “They took my life and they made it right,” she said outside the court.
The ruling underscores ongoing shifts in the legal and medical communities’ approach to cases involving infant deaths previously attributed to shaken baby syndrome, reflecting advances in scientific understanding and forensic review processes.
