My youngest brother has an apartment at 811 2nd Ave East, Unit #1 in Culbertson MT. His name is Lloyd J. McDonald. On Tuesday he passed away. I gave permission to his landlord to enter the apartment to be sure everything was OK. There was no mail around, and I am inquiring as to how he would receive mail in Culbertson MT. Thank you for your attention to this matter.
