In 1970, at the age of 17, David Milgaard was wrongfully convicted of murdering Gail Miller, a nurse from Saskatoon. He would spend almost 23 years in prison for a crime he didn't commit before his conviction was overturned by the Supreme Court of Canada in 1992, and exonerated by DNA evidence in 1997. This DNA evidence would eventually convict Larry Fisher in 1999, 30 years after the killing took place.
