Bodom
A lake in Finland where four campers decided to camp at. Late that night, an unknown killer attacked the tent by collapsing it and stabbing downward multiple times, injuring one and mutilating the other three. The badass Black/Power metal band Children of Bodom was named after this lake. And no, to the dumbass at the bottom, BODOM WAS NOT A KILLER. BODOM WAS A LAKE. The killer is unknown.
Children of Bodom are amazing.
