Due to privacy laws, you have to be in contact with someone, they are not allowed to tell anyone who is and is not staying with them. You can ask for a message to be posted to that person in case they are there. The only time that they share if someone is staying there is if the authorities need that information for justice or safety.

I dont believe shelters give out that information due to the Privacy Act of 1969
