Life is bittersweet sometimes, I was a young man when I had something similar happen.

I was fortunate to have had a decent amount of community support, that was a good 25 years ago.  Hopefully the son will have the same.  I've been paying it forward ever since whenever I can I never forgot what my community did for myself and my family.

One bit of advice : the families impacted will be flooded with FOOD with great intentions, and the last thing those grieving want to do is eat.  What really was helpful was assistance with normal stuff like painting, yard work, house maintenance, esp. if they have to make a tough decision like selling a house to cover any estate expenses.

The silver lining with my situation when I was young, it forced myself to learn some blue collar skills that to this day continue to pay dividends to myself and now my Denver community.

Best wishes to those impacted.  Time heals all wounds.
