Criminal profiler Pat Brown gave us 5 theories:
1. As assassin which was hired because of his insider trading. In other words, someone hired an assassin to take him out because he was about to squeal on them. This guy makes 10 million/year, why is he doing insider trading?
2. His wife hired an assassin to take him out.
3. Someone shot him b/c he was denied healthcare (or his family member was).
4. Someone shot him as a political statement, like he views the CEO as the symbol of what's wrong with the system.
5. Lastly - and this is a little far-fetched, but this has happened before - the United CEO hired a hitman himself. The reason he would do this - he's facing lawsuits, and possibly would get convicted for insider trading - so he wants to end it all and make it look like a homicide. That way his family still gets the insurance money.
The weirdest part is that the hitman only waited 5 mins. Like, how did he know that he was going to be walking across just then?
