Please ping me if this turns out to be yet another hoax so I can add it to my list.
Thanks.
Here's the only report I've seen (found via google I hasten to add) that dares to offer the motive given by the perpetrator:
A female student turned herself in, claiming that she and two others hung the noose as a piece of ironic "performance art."
(It's self-evident the university knows what's going on here -- the suppressing of this "motive" is more pointlessly PC than the suppressing of what everybody here knows.) Well there we are, a little "irony", a little "performance art", statement -- whatever the statement was supposed to be -- is made. Problem solved? As the comedians say, "wait for it...!":
"But activist students interpreted the act as a sign that a threat still looms on campus."

Oh, and there's still no mention of the criminal's name or race.
