Was wondering if anyone can provide me with information and or where to find information about the "Circleville Letter Writer"

..."anonymous letters threatening residents of central Ohio"

The episode debuted in 1994 on Nov. 11th
And I would really like to read more about it.

You might remember it as the episode where Robert Stack actually recieved a threat from the writer.

Please any kind of help will be appreciated

I did a search on this board....here's the results -
