As much as I love seeing these creepy mystery videos, I have to be honest and say that for the first time, Matthias has disappointed me. It could be from the fear that impaired his ability to think straight so I can understand that. The fact that he told Sam to try her fingers on the safe, instead of trying to see if there was still a finger print on there is frustrating to me personally. Movies have often shown that you can take a finger print from an old surface, and use that on a finger print scanner. However, I have never tried this, nor have I ever seen anyone attempt this in real life, therefore I can't say with certainty if it could've helped.
