This story is rather interesting to read but not to heed or even
pay attention too. It's rather nice, exactly like an urban legend,
no firm evidence, no one to relate the story to, it's always "my
fren's fren" or "my fren". Exposing him will leave you in trouble
or unable to expose him will leave you in more trouble? And
suddenly this jerk vanished without a trace, no pic, no name, no
contact. IMHO, I think this jerk doesn't even exist at all. Nice
story bearie000. 
But then you did a good thing to remind women out there that there
are men capable of heindous deeds just for sex. Women by far does
the same thing, not for sex, but for a comfortable life and for
fame.
