C said the person was 120-140 pounds, I believe (my computer is on the fritz so I can't get to my notes) and short, which would point more to female body build than male. Could still be a young man though.
glorias, it seemed she estimated the person's height to be around the same as Gail's, which as I recall, was 5'8" . To me that would be tallish for a woman. I could be wrong--this is off the top of my head. I'll check back and see if I can find exactly what she said.
....Okay, here's the link and the quote: http://chattanoogan.com/articles/article_203258.asp
"C said she never saw the face of the female passenger. She said she appeared to be from 5'7"-5'9" and weigh 120-140 pounds."
That weight would be sort of thin and slight for a male.
