The autopsy report. Meyer describes them on page 4. Last paragraph. It is the 'cloth hair tie which is listed in the evidence taken from the body as being black/red/white. http://www.acandyrose.com/12271996jonbenet04.gif
PR's statement was in one of her many pages of depos. I don't save every one. If I come across it I'll post the link. She was being questioned about the odd hairstyle, and being shown photos of the White's. Of course, we've never seen those photos.
Thank you.
