JFK witness Lee Bowers dies suspiciously

Witness after witness ended up dead after confessing knowledge of something they should not have known. Lee Bowers was one such witness. Lee was overlooking the scene where the assassination occurred where he had a near bird's eye view of the grassy knoll. He saw two strangers behind the fence just before JFK was shot and saw a puff of smoke. This confession was clearly unacceptable for the narrative they wanted to push.

But you're not going to believe how he died:

The official story is that his car left an empty road and inexplicably struck a concrete bridge.
