Who actually hit Natalee?

One highly controversial piece in this interview is Joe Scarborough and his own investigation of that night. He claims to have spoke to someone that was there, that said twice Joran approached Natalee and she rebuffed him. The third time he tried to approach her he got so mad at her disinterest that he hit her with a closed fist?
Since by all accounts what Joe said is absolutely not true, it does make you wonder who actually hit Natalee, if someone did with a closed fist.

This would be one of many interviews to come where Beth would be so sure of events that even three years later to most people, are still not clear at all.

What became of this witness?

Beth Twitty would begin speaking about a witness, another young girl that approached her in Aruba with another Joran van der Sloot story that paralleled Natalee's except for the ending.

Beth said that an 18 year old tourist came up to her and shared her experience with Joran and the Kalpoe brothers. She too, was at Carlos 'N Charlie's, and it was late almost time for closing. This anonymous witness would say that Joran was always scoping out the females at Carlos 'N Charlie's.

These are Beth's words

There was a similar encounter as told to her by the anonymous witness. This is the same anonymous witness that no one has ever really heard of after Beth would speak of it adamantly back in August of 2005.
