As I mentioned in the post, I read that Hao Gu was found dead in Dr. Bing Liu's car, most reports say it was his car.  If it was indeed Liu's car, it's curious to note that the location was on a different street, 100 yards away from Liu's building.  Looking at the map it occurred to me that it could be possible that a third party was involved (that was before I read this article).  I also wondered if there was something between the two men (such as a gay relationship or some other personal involvement).
