This entry in the series will address the use of genealogy as a criminal investigation technique in Denmark and Sweden. In 2020, the Swedish Police solved a 16-year-old cold case using forensic genetic genealogy. Earlier this year, the Danish and Swedish parliaments voted on legislation that would allow police to use DNA from genealogy research as a tool to solve crimes. The Danish Parliament approved the proposal and the law now allows investigative genetic genealogy to be used in limited cases, whereas the Swedish Parliament voted the proposal down. This webinar will describe how genealogy research and family DNA searches have been used in Denmark and Sweden, the legislation supporting their use, and how the national laws relate to the European Union rules on the right of privacy and family life, the GDPR, and the two countries? international human rights obligations.
