Quite an interesting story about the assassination of Durham White
Stevens;http://www.koreanamericanheritage.com/kna.htm

Yeah, I've read that version, which, of course, could be just slightly
slanted to the Korean POV. That said, it's about the only history on the man
I could find online. I guess I'll have to break down and go to ugh! *the
library*. Oh, well. That'll give me a good reason to visit Boston on one of
these cold winter days. I mean, how expensive could it be to park in Boston,
anyway . . . ;-)

Go to Google Scholar and type in "Durham White Stevens" (remember the
quotation marks). There's about twelve more references to him there.
Probably would find more with some differing search strings.
