Tom, you quoted a really important passage in the article: "Osborn says a man named Jarriel Johnson drove the accuser to the Durham Police Department to pick up her belongings March 21. The motion points to a statement from Johnson saying the accuser engaged in sexual activity with at least four different men from March 10 to March 12."
The reason I think this is so important is because it supports the idea that Mangum wanted to bail out of this accusation early on. There would be no other purpose in Johnson making this statement to the police. The statement would clearly be something said by someone who wanted to "dilute" and cast doubt on any evidence of a rape by throwing a great deal of doubt on where any injuries, semen, etc. came from, similar to the widely publicized Kobe case. Combine this with Mangum's statement to UNC Medical that she drank a great deal of alcohol the night before, and a picture of an effort to recant or muddy the case appears.
