Like OJ
A friend of mine heard a story that Nicole had been passed around to some OJ friend(s), particularly great running back Marcus Allen. (Don't dump on me if it isn't true, the point here is the next remark).
My friend's comment was that OJ had killed Nicole out of insecurity. It was OK for her to date one of his friends, but let her think about going out with a mild-mannered Jewish accountant, and... off with her head. (No substantiation for the second assertion either, but maybe OJ thought there was more between Ron Goldman and Nicole than dropping off her sunglasses.)
