I don't go to cemeteries unless one of my Family or a close Friend is being laid to rest. And, once that happens, I don't go back to their graves. They live on forever in my heart and mind.
I would rather sit on a memorial bench in a garden, surrounded by the hustle and bustle of Life, observing the craziness around me, than visit a grave site.
Just my personal preference.
As to why other murdered/missing persons don't have memorials, I can think of several reasons. If the person was murdered, maybe the Family wanted to put the whole episode behind them and live off of their good memories as well. Maybe the deceased was cremated, and the ashes scattered in the deceased person's favorite place. Or, maybe their assets were given to charity, per their request.
As to missing persons, I think the hope always exists that said person may come back through the door alive and well someday. Granted this is rare, but there is always hope.
JMVHO.
Just had a post deleted because it was “depressing”. Didn’t see that as a rule violation.
