Toronto resident Laura Babcock, who is shown in this Toronto Police Service handout photo, disappeared in July 2012 shortly after her friends said the University of Toronto graduate&#39;s mental health issues took a turn for the worse.  Two years later, police announced that Babcock had been murdered and two men, Dellen Millard and Mark Smich, had been charged with first-degree murder in connection with her death. Police previously said that Babcock had been romantically linked to Millard. (The Canadian Press/HO-Toronto Police Service)
