I'm not sure if its random or glitchy. I managed to open the basement and escape with the evidence. However, I did the exact same thing that I did the very first time. The first time, I didn't escape. The basement door didn't open. I tried it again (since it was the only logical thing I could see to open the basement door) and I made it out. Either way, it was fun. A little frustrating, but I still enjoyed it. Thanks.
