I believe Acevada had him killed somehow. His character was introduced to show the cutthroat intensity and the power of Aceveda and bring in the the theme that Poloticians are above the law. Claudette said something that reinforced this viewpoint. Something to the effect of, "I'm sure you won't let the election stop you"
The reason his campaign HQ was threatened is because people know that he was behind it. Sure Andre 3000 wasn't even a threat but hhe insulted Aceveda and made him look stupid so he had to die.
I think that could be a great storyline but why bring it up when it is never going to be looked developed, same with Lloyd.
