Dr. Dirk Huyer, Ontario's chief coroner, on Friday released the identities of all 10 people killed in the April 23 van attack in Toronto. FingerprintsFingerprinting is often the first tactic investigators try in order to get a scientifically sound identity confirmation, Huyer said. Dental recordsDental records were used to scientifically confirm the identity of the majority of the 10 people killed in the Toronto van attack, Huyer said. If the person they believe was killed had their appendix or gall bladder removed, the coroner's office can check to see whether the deceased person had undergone the same procedure. "You have to be quite confident that the person who used that razor is in fact that deceased person."
