On October 27, 2007, Joel Lovelion was dressed as a fan of his favorite hockey team for a Halloween party hosted at the Broken Drum bar in Grand Forks, ND.

Before the night was over, Joel would be dead, beaten to death by another partygoer.

The only physical evidence found was something yellow from part of a costume. The suspects include a penguin, a clown, a gangster, and a construction worker.

Will the murderer be unmasked or will Joel’s killer remain disguised?
