Hi and Welcome to Ask A Doctor service. Yes the situations is not interesting only but also a bit oncerning .The question is more related to social then medical issue but let me offer a possible solution.There are few possible option here how to approach .The first thing you can do it to meet the person and dicuss with him what you observe .Ask his thaughts if he can offer any explaination.If this is not possible for you , you can ask the managemnt of the apt complex. They may talk to him and know more about him and may answering your questions.I am sure you would know quite enough this way .

Hope thi answer help you.Let me know if you have any mor questions.
