I would treat it as foul play. Especially look at the husband. Something is not right. It sounds strange that the last thing he heard her say is she needed to get some fresh air? Look very closely at the husband. Unfortunately, 9 times out of 10 once a wife goes missing the husband has played a role.
Exactly! Literally who says that “ I need to get some air, fresh air” and leaves the house in pajamas bottoms and a shirt, I’m pretty sure that sentence is only used in the movies. In my life I’ve never said that – it sounds fake & dramatic And she just couldn’t walked out her front door to get Air or out to the balcony or back yard? Sounds like BS from the husband. Also sounds like what she probably said was more likely “I need some time or space from you” like she had an argument with her husband.
