Vote on whoever killed MARIO here.

with the new information regarding fireworks, and bee's testimony that she saw dude throwing fireworks around, i now consider him the most likely suspect

You all have chosen to execute DUDE, who was indeed THE KILLER.

His role was the ULTIMATE TIMER, with the following abilities:
+A bell in your room will chime 4 times throughout the night, each separated by an equal amount of time having passed. Only you can hear it and only if you are on the second floor, and it cannot be moved elsewhere.
+The first chime is at the start of the night, the fourth is at the end.
-If you are asleep or knocked out when the bell chimes, you won't be aware that it has. However, one can wake you to start the night.

The door to a SMALL DARK ROOM opens, tossing DUDE inside. Suddenly, the room is filled with light, as TEN FIREWORKS are suddenly lit by themselves inside the room. They explode, gibbing him into nothingness.
