So so sorry to hear that
No words can express how your feeling
God love him i pray he is safe in gods arms
But what a good fella he was
In his death he helped save 4 others. there will always be a part of him alive
Regarding christmas its gonna be hard, bittersweet so am just gonna say to you that you and your family will get though it with some joy and some sadness. some happy and sad thoughts.
Think as a family you will think of something to do for this brave good man
