Do they know who did it? I read in my Gainesville paper this morning that they were looking for a white man around 25 years of age, wearing a black cap with some kind of logo of a red spear. But the paper probably goes to bed pretty early, so possibly more information has come out.
See

for picture and more on slaying.
