Maybe I'm wrong, but seems to me that investigators have next to nothing gathered up that would prove, in a court of law, just who committed this crime. At times, this presser seemed to be like law enforcement was trying to provoke whomever is on their radar. Seems odd to me that the new sketch is so different than the video of the man on the bridge and the earlier sketch of the man on the bridge. What I gleaned from this pressor... they have little or nothing, even after 1000s of hours of investigation. It's their job to gather evidence that can be used in a court of law, and now over two years later are asking the public to point a finger. They want an eye witness to come forward, someone that has info that could be helpful in a trial. I think that I can understand why the families may have left in not so good a mood.
