My heart aches

A terrible tragedy occurred on New Year's eve. A family of four died when their private airplane crashed into a neighborhood. A father, mother and two sons, but they also have a daughter and she is left to mourn. They just endured the death of their grandfather and their grandmother and this girl are left to carry this now too. I am just so sad for them. My BIL is close with the family and is really torn up over this. My sister helped the grandfather die with dignity (she was his hospice nurse) and became close with them as well. I just don't have the words for their loss. It is just not fair or right!
