Richardson family murders of 2006

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 and her 23-year-old boyfriend Jeremy Steinke, now going by the name Jackson May.[5] Richardson and Steinke were each convicted on three counts of first-degree murder. Richardson, who had turned 13 before being convicted, is thought to be the youngest person in Canada ever convicted of multiple first-degree murder counts. Her 10-year sentence was completed on May 6, 2016. from Wikipedia
