Will new leads solve this 10-year-old cold case? The police say they won't quit until they find Sonia Varaschin's killer. Police started an investigation into the 42-year-old nurse's death after she didn't show up for work at a Mississauga pharmaceutical company. Her remains were discovered by a citizen a week later in Caledon, approximately 12 kilometres from Varaschin's home.

Shannon Madill had everything going for her; she had just landed an audition for a role in a television series; was looking forward to moving from Calgary to Edmonton; the audition was recorded on video; hours later she vanished.
