Ontario’s highest court has acquitted a Trenton woman convicted in 1999 of killing her infant son based in part on evidence of now disgraced pathologist Dr. Charles Smith, calling the case a miscarriage of justice. Both the defence and Crown called for Sherry Sherret-Robinson’s, acquittal at a hearing today in the Court of Appeal for Ontario. The Crown said new expert evidence “conclusively refutes critical aspects” of Smith’s opinion. Smith concluded the boy, Joshua, died of asphyxia and that his death was suspicious due in part to a skull fracture and neck hemorrhages. But Dr. Michael Pollanen, Ontario’s chief forensic pathologist and other experts found there was no skull fracture and the neck hemorrhages were in fact caused by Smith during the autopsy.
