The conviction was overturned based on fresh evidence submitted by Gaskin's legal team, led by veteran lawyer James Lockyer. Gaskin, who served two years in prison and lost custody of her other children during the case, broke down in tears upon hearing the verdict.

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."
