DNA的进步解决了加拿大的寒冷案件,导致几十年后定罪。 DNA advances solved Canadian cold cases, leading to convictions decades later.

2025年,DNA分析的进展,包括公共数据库匹配和遗传基因学,导致加拿大各地多起寒冷案件得到解决,例如1994年Marie-Chantale Desjardins被谋杀和2008年Catherine Daviau被杀害,导致在犯罪几十年后定罪和辨认。 In 2025, advances in DNA analysis, including public database matches and genetic genealogy, led to the resolution of multiple cold cases across Canada, such as the 1994 murder of Marie-Chantale Desjardins and the 2008 killing of Catherine Daviau, resulting in convictions and identifications decades after the crimes. 魁北克的法医实验室每年处理数千个样本,利用现代技术重新审查旧证据,在1970年代和1990年代的案例中协助新逮捕。 Quebec’s forensic lab processed thousands of samples annually, using modern techniques to re-examine old evidence, aiding in new arrests in cases dating back to the 1970s and 1990s. 在执法部门庆祝进展的同时,关于使用DNA数据库的隐私和伦理限制的辩论还在继续。 While law enforcement celebrates the progress, debates continue over privacy and ethical limits on DNA database use.
