‘And who’s to say this article is correct?’

since the entire thread is based on the article, your understanding after reading said article is quite incorrect based on the stated content...the actual truth could of course be something else...

It said the caller was "unidentified." That means that until we know further, it could have been McMichaels, or it could have been someone else.

We will eventually find out who made that call, and if it was not McMichael, it was likely someone known to him, for how else was he made aware of the situation?
