Sterling City Library Blaze

In 1983, 14 children went missing. A week later, the Stirling City Library went up in flames. The case went un solved. Three years later, a photographer, Mary Thomas, went missing on June 13, 1986. There are no records of such fire, but it is told some one deleted all information based on the case. It is rumored Mary Thomas sacrificed her self in order to kill slender man.
Who is this woman, and what happened to the children? Why are there no records of the library blaze? Nobody knows.
