 An independent review found that neither the laboratory's director, clinical toxicologist Gideon Koren, nor his staff, had the qualifications or expertise to do that kind of forensic work.Prior to this Koren was officially reprimanded by the Ontario College of Physicians and Surgeons for writing harassing anonymous letters to Nancy Olivieri and three other colleagues, about which he then lied repeatedly to conceal his responsibility.The Ontario College of Physicians and Surgeons also cited him for additional misconduct in research.
