New serial killer on the loose in Pittsburgh!

There have been 7 victims so far and all of them have been killed. The killer has sent several letters to the police and all of them say,” they won’t find me, I am too hidden, they report me as a old creepypasta that is dressing up, my victims will not hear me, for I am silent, my victims cannot see me, for I am invisible.” Those letters are chilling. Although one man saw a guy who appeared to have a long red smile and very pale enter one of the victims houses at night. This is channel 46 news which brings you Pittsburgh news as fast as possible.
