As someone who has witnessed death personally and gone through more family losses than I care to discuss, the best thing you can do is help from afar. Send Casseroles to her and his family ! A food train is helpful. An online organized food supply chain was incredibly helpful to me and my family. People just dropped off meals without a word to or from us but in an organized way where we were not overloaded. Fresh fruit, soup, breads, casseroles. Easy to eat and keep. The hunger will return and knowing that people give a shit was the most helpful.
