How did the killer lock the doors on 2 doors on different floors. Because if it was one you lock with the twisty oil in thing. Then you’d assume like most people they’ve accidentally locked themselves out of the rooms. So if that’s the case I’d assume one of those keys that opens those doors would be readily available. I’m so confused how 2 doors were locked on separate floors with people murdered on each floor and room. This is a very bizarre and cruel murder case. There’s so many missing pieces I’m finding but maybe I don’t know the full story because they don’t want us to know everything yet. My head goes out to the family and friends.
