Before any fanatics get to you, Slenderman and Jeff the Killer aren't real either. In fact, the creator of Slenderman has stated multiple times that he's a fictional entity.

If you want to read about something that happened in real life, here are a few.
 * "The Deaths of Lela and Raymond Howard"
 * "Plague of 1918"
 * "Chago"
