Idiot or not this is just fucking SAD
You cant really blame an old guy that just went through the worst time in his life for falling for something like this....
Yes he most likely is not all there, but also remember that he did not grow up with the internet and most likely knows very little about it.
Yes he should have cought on, and the family should have as well
But its still fucking sad and people that do these types of things should honestly burn in hell
