I'm not saying she would have been open about it. I'm saying IF your scenario is valid, she would not have the same need to cover up her electronic footprint as the guy would. He would delete emails, phone calls, etc. Maybe even have another phone or only contact her via his work computer. Etc, etc. Yes, she would likely keep the relationship secret but she probably wouldn't go out and buy a burner phone, delete messages, etc. She would have no need to do that. Also, having known more than a few women and men in so-called secret relationships, I can say people ALWAYS know. You might think nobody else does, but they do. There would be missing gaps when she came back on weekends, people would have seen them out. Because she stayed with her mother and he was attached, they would have had to meet somewhere, most likely a hotel. After the murder, people who saw them out or at the hotel or whatever would have come forward. And again, there would be a record on her computer, her tablet, her phone - EVEN if she deleted things, which I very much doubt she did. Add to that the manner of death, where the body was found, general reports about her lifestyle and the time she went missing. None of these support the theory of a hidden relationship, whatever your past experience tells you.
