Found this video, which could be heavily related to Jessica. It was released months before the marble hornets jessica videos.

Shit. Shit shit shit. So this video now raises a question in which my own personal issues with people on the internet has to be leveraged against how awesome I think Marble Hornets is. I
really hope this isn't some jackass taking what Marble Hornets is doing and trying to hijack some portion of the storyline. On one hand I don't see why the guys at MH would give such a massive, gigantic bit of information away while their show is building mystery around the character of Jessica. Would the internet give us some dude making a MH documentary that gets in the way? Hell yeah.
I'm giving it a 50/50 chance that this is a part of the "MH" viral because this was just so good, but the other side of the coin is that this is just some sort of internet dude getting in the way and trying to get attention for his additions to something that someone else is doing.
