Do these people have names? Who are they, and what did they say?
So, "a woman who only gave her first name on a local radio station". That's a reliable-sounding source. How do we know this woman was even at the scene?
If you're referring to "Josie", she never claimed that she witnessed the event, she was providing Wilson's version of the story as she says was told to her, presumably because no one has really seen his detailed account and she wanted to get this information out there.
