To your family may God's grace comfort you and your family..
I did not know your dad but I lived two doors down from your uncle Alex and aunt Sheryl in Maxwell Park, this was in the 1980's... Vivia and Mason played with my children. I pray that you somehow find peace. it's so unfortunate that this happened, he appeared to be a good man.
Look to God for peace and comfort.
God bless you and family.
