Here is the difference. CM created and deleted and backdated checks, written out to himself, from Joey's account, beginning Feb 1st. AND he called QBooks, posing as Joey and tried to get the online records shut down and erased.
On top of that, CM lied to investigators and told them that Joey gave him those checks on the 4tth, the same checks that CM actually created and backdated himself.
DK was not involved in any of that.
It doesn't matter if CM ever threatened Joey, because as far as any one knows, he wouldn't have done so. He had no reason to do so until things went sideways at the very end.
And he wouldn't have threatened him then because he wanted to do a sneak attack and blindside him. He is a conman and knows how to hoodwink people.
