Although it could have.
There is too much other evidence that would indicate that something else happened, too.
And since we don't know, it should be investigated because foul play could be involved in the orginal incident. And even that doesn't really matter except to bring a possible criminal to justice. They had to right to murder an innocent American lady.
I'm glad you brought it up just for my own review, for my own personal knowledge. Nothing to do w/this case.
thanks again.
