The Aporia · Ontario woman appeals conviction in infant son’s death based on new medical evidence

Jennifer Gaskin, an Ontario woman convicted of manslaughter in 2002 for the death of her two-and-a-half-month-old son Joseph due to alleged shaken baby syndrome, is appealing her conviction using new medical evidence. After re-evaluation by additional experts who could not rule out inflicted injury but also noted that premature babies like Joseph might die from sudden infant death syndrome, Gaskin’s legal team argues for a reassessment of the case. The Crown supports this appeal, stating that fresh evidence has cast significant doubt on the original medical findings and requesting an acquittal.

Story summary

Jennifer Gaskin, convicted of manslaughter in 2002 for her 2.5-month-old son Joseph's death in Ignace, Ontario, was acquitted by the Court of Appeal for Ontario in September 2023 after new medical research cast doubt on the original shaken baby syndrome diagnosis. The case originally relied on expert testimony that labeled the infant's injuries as inflicted, but later reviews and new evidence suggested the possibility of sudden infant death syndrome or accidental causes. Gaskin spent 18 months in prison and her two other children were adopted out after Joseph’s death. With fresh expert analysis, both Gaskin’s lawyers and the Crown submitted to quash her conviction, arguing that current scientific consensus overwhelmingly undermines the original diagnosis. Judge Peter Lauwers referred to it as a "miscarriage of justice."
