Sandude, you can be "convinced" all you like, but there is no way you KNOW that to be true. He was jailed long before Aug. 1, in any case.
That is correct, I don't KNOW for sure. It does fit in with all that we know happened between the 1st of August and the 14th of August. We will find out one day I'm sure of that. At some point the family and LE will let us know whose voice Mary Katherine did recognize.
