I'm not saying all have killing rituals but when i was a freshman in high school, there was a vacant trailer back this dead end gravel road by my friends house. he kept saying that late at night cars would go back there. so one day around noon, we snuck back there and went into it. scariest sh*t i've ever done. there was no furniture (chairs,beds, couches) inside the trailer.they had ripped out all of the carpet and on the main rooms floor there was a big circle like symbol spray painted, and there was dried blood in the middle. they had built a structure out of 2x4's that looked like a swingset frame, and i'm not lying one bit, there were 2 dead cats hanging from it. in what was supposed to be a bedroom, we found a satanic bible.
we got the hell out of there as fast as we could.
