Shop NYC Top

I come to this subreddit as I am desperate for help, I apologize if that is not the proper place. My sister has been living in NYC for almost 10 years now, she is french but got a green card. Almost two years ago she had some kind of burn out/mental breakdown and lost her job and all her friends. My mother and I finally convinced her to come back home, and last time we spoke to her she was supposed to leave her flat and buy a one-way plane ticket.

My mum speaks to her almost daily, but it’s been 3 weeks now without a single word from her. Now to be honest she already disappeared for a few months last year, so it could very well be her having another mental health crisis. But we have absolutely zero contact in NYC, all the people we knew moved out of the city. I tried calling her precinct but they tell me they will only do something if the request comes from an American citizen or if we are physically here.

We simply have her address and that’s it. What can we do to at least check if she’s home or not ?

Thank you for your help.
