That's when EN reportedly told Krisztian. But in the same affidavit, "Altergott said Nowsch never told him the people in the green car ever shot at him."
The warrant affidavit makes it sound as if EN's conversation with Altergott & Krisztian was one conversation with all 3 of them together. If so, then one of them is either misremembering that conversation or lying. Or maybe Altergott left the room (bathroom? get another beer?), and while he was out of the room, EN told K no one had shot at him.
Either way, that same affidavit says that Brandon says that he fired at EN in the cul de sac, and that police found 9mm casings in the cul de sac.
Both can't be true. Either Brandon fired, or Brandon didn't fire. I tend to believe that Brandon fired. Not only does that correlate with the fired 9mm casings found by police, but it's actually one of the very very few statements by the Meyerses that hasn't changed at all. (Although in early reports they said Brandon was firing a shotgun, but they have consistently reported that he fired.)
So IF EN told one or both of his friends that no one shot at him, he was either mistaken or lying. Or Krisztian might be mistaken or lying about EN telling her that.
