On the night of April 14 and the morning of April 15, 2014 there was a full, blood moon, as well as a lunar eclipse. This created a very creepy atmosphere, which, naturally, lead to students at the University of Calgary to throw parties and generally be collage kids.
Unfortunately, the creepy atmosphere also lead another student to a different activity. Matthew de Grood murdered five students because he claimed they were werewolves.
The Canadian courts are currently ruling on the case now. You can find more details about the case here.
