For your notes:
Mario "Buchi" Rasmijn (Aruban Park Ranger = APR)
Greta kept calling it "a hair" and the APR corrected her and told her "It not A hair" it's duct tape that I found on the rocks here on the coast. He says "ahhhh it's look like two colors of hair. One lighter than the other one, or ah you can say one is darker than the other one.
Found on Sunday at 11:45am during his regular shift patrol and he was not "tipped" off about it.
Greta asked him he could see the hair pretty easily on the duct tape? and he responed "not really". (so he saying that you could not see it easily but that there was hair on the duct tape - I take it also that that the hair is 2 toned and not that one hair is a different color than another, even though he tried his best to descibe it for Greta. The guy was having a rough time understanding what Greta was after with her questions. English is probably not is native language.)
The Transcript should be up sometime in the next few hours.
I must really be out of it because I though this guy said the hair was not only two-toned but 6 inches long.
There are a couple of transcripts on this thread posted yesterday that describes the strands of hair found on the duct tape.
Since the park ranger, Mario "Buchi" Rasmijn, either did not see or "not really" could see the hair pretty easily I would not put a lot of weight in his own or coached response to Greta.
Regarding the two-toned hair: Even if Natalee's hair is natural (not dyed or even highlighted), it can easily be two-toned. When I was a teen I would pluck out a long blonde hair and find a totally different shade toward the scalp than the basically colorless shade at the ends.
