Question: The most recent serial killer documented in the book "Cold North Killers: Canadian Serial Murder" was arrested in what year?
Context: Cold North Killers: Canadian Serial Murder is a 2012 Canadian non-fiction book written by Lee Mellor and published by Dundurn Press.  It documents the lives of sixty Canadian serial killers, with the earliest being Edward H. Rulloff and the most recent being Russell Williams.  The book uses Katherine Ramsland's interpretation of what constitutes a serial killer—someone who has killed at least two people on two separate occasions, and who attempted to or likely would have killed again—as outlined in her 2007 book "The Human Predator".  "Cold North Killer's" own definition of what constitutes a Canadian serial killer includes both Canadians who committed murder abroad (such as Keith Hunter Jesperson and Gordon Stewart Northcott) and non-Canadians who committed murder in Canada (like William Dean Christenson and Earle Nelson). Raymond Martinez Fernandez (December 17, 1914 – March 8, 1951) and Martha Jule Beck (May 6, 1920 – March 8, 1951) were an American serial killer couple.  They are believed to have killed as many as 20 women during their murderous spree between 1947 and 1949.  After their arrest and trial for serial murder in 1949, they became known as "The Lonely Hearts Killers" for meeting their unsuspecting victims through lonely hearts ads.  A number of films and television shows are based on this case.
