The Serial Killer I Couldn't Catch

Ten years ago, the trial of Canada's most prolific serial killer opened in Vancouver. The case dated back to the 1990's when Detective Constable Lorimer Shenher was charged with investigating the disappearances of sex workers in the area. After several tip offs Lorimer became convinced that pig farmer Robert Pickton was the man responsible. But despite all his efforts he couldn't properly investigate Pickton, something that's haunted him for years. Some of the details that follow are disturbing. Image: Robert Picton Credit: Getty Images
