Luka Magnotta: True Story of a Canadian Psycho (Crimes Canada : True Crimes That Shocked The Nation Book 5) - Peter Vronsky, Rj Parker, Aeternum Designs, Cara Lee Carter

This a good short history of the Luka Magnotta case. You should be warned that there are some graphic photos and description, but Carter warns you in text so you can skip those sections.

I'm not sure if the introductory bits about psychology is correct though. It seems like an over-simplification.
