My sister and I had a falling out a few years ago to punish me. She has blocked my father from me. He is in a nursing home with no phone. She has complete power of attorney they will not let me know how my father is. He has tested positive for covid 19. This was told to me by another sibling. I never hurt my father in any way shape or form. He is 87 yrs old. How can this be legal. Please help. Time is running out
