My 85 Y/O father has been traumatized by the sudden death of my younger brother (aged 51) in 2015 so much so that he has been highly susceptible to Nigerian scams which in previous years, he would've laughed at. He has lost upwards of $30,000 and possibly more in this past year alone to various scams. I am the only child living and am aged 61. I don't know how to stop him from responding to these people---it is all done online via e-mail. I did convince him to go to the FBI and we filed an IC3 report but so far nothing has been done (but it was less than two weeks ago; I know they are back-logged). I am also caring for my 83 Y/O mother and unfortunately, she is of no help insofar as controlling his behavior. He is still insisting that these "accounts" are real despite the fact that I keep telling him that the only money existing in these scenarios is the money he is putting OUT.
