This French Canadian whacko is completly deranged.  Gateway Pundit is staying on top of this story and they have posted more than a couple of really creepy updates.  Including:

There are reports Luka fled Canada to France. Interpol has added him to their list of international fugitives.
The National Post reported – Luka left a note in the box with the severed foot warning authorities of 5 other packages. (One package with a hand was found this week). In a note Luka said he planned on killing again.
A video which purportedly shows Luka Rocco Magnotta brutally killing and sexually assaulting a naked man appears on a Canadian-operated website called Best Gore.
The Montreal Gazette says Magnotta has written a six-step process for vanishing and losing yourself.   Now he’s gone. And, Luka Magnotta has promised to kill again.
Montreal Craig’s List users posted warnings about Luka.
