I found the source about the fibers. I know it's not going to pass muster for certain posters, but here it is: ST, "JonBenet Inside the Ramsey Murder Investigation. (Hardback edition)
Page 254: Back in February 1997, several fibers were taken from the sticky side of the tape that had been against JonBenet's face.
When Team Ramsey finally gave us the clothing purporting to be what John and Patsy were wearing on December 25 and 26, one of the bagged items was Patsy's red-and-black-checked jacket.
The Colorado Bureau of Investigation labs ran comparison tests and reported that four fibers that had been discovered on the tape were chemically and microscopically consistent with the fibers of Patsy's jacket.
*************
Key words, sticky side of tape, four fibers chemically and microscopically consistent with the fibers of Patsy's jacket.
Please don't say the fibers don't exist anymore because I have shown proof positive that they do. Unless the CBI is on the conspiracy to frame the Ramseys too. JMO
