Jay-Z had Cathy White (His Alleged Mistress) Killed
Cathy Koreana White died of a brain aneurysm in September 2011; rumors had spread a year prior to her passing that she was Jay-Z's mistress. As a result, her passing triggered a wave of speculation and conspiracy theories involving Jay's attempts to silence her, particularly since her death occurred around the same time that Beyonce announced her own pregnancy.
Never mind that, in the words of one gossip blogger, "The detective told me they found nothing suspicious in both the toxicology or autopsy reports." Because the detective also definitely acted "vague and apprehensive about giving me more specific details."
I think we all know what that means: Jay-Z must have sacrificed an alleged lover in order to retain his standing in the Illuminati.
