I typically have very little sympathy for victims of scams like the Nigerian scam. After all, such things require the victim to be rather greedy and usually somewhat vain.
But this story has me rethinking those assumptions.
Basically, an 89-year-old apparently well-respected university professor was separated from millions of dollars of his money by the Nigerian scam. I read up on scams a couple of months ago as research for my novel. (If you ever need to do this, Fay Faron's book Rip-Off: A Writer's Guide to Crimes of Deception was a really excellent resource.)
Going on what I learned from Faron's book, how the UCI crime happened illustrates perfectly why the scams target old people and how well that works. In this case, the crime victim ever lied and claimed he'd lost the money in "bad investments" rather than admit what happened.
I can completely understand that, especially in a man who got his fame by pointing out Ronald Reagan's mental difficulties awhile before other people could see them.
