After a torso is found floating in the Oshawa Harbour, the family of 18-year-old Rori Hache is horrified to learn the human remains belong to the missing teen.

During the police investigation, a second young woman's DNA is identified, that of 19-year-old Kandis Fitzpatrick. Worried there could be more victims, two families must join forces to bring a predator to justice. And Kandis' father, in his first-ever in-depth interview, opens up to reporter Catherine McDonald.
