Richardson family murders

Three members of the Richardson family were murdered in Medicine Hat, Alberta, Canada, in April 2006. The murders were planned and committed by the family's 12-year-old daughter Jasmine Richardson, alongside her 23-year-old boyfriend Jeremy Steinke, now going by the name Jackson May. Richardson and Steinke were each convicted on three counts of first-degree murder. Richardson, who had turned 13 before being convicted, is the youngest person in Canada ever convicted of multiple first-degree murder counts. She received a sentence of 10 years' imprisonment, which was completed on May 6, 2016. Provided by Wikipedia
