THere was a 1 3/16 inch area. Again it was not photographed as per protocol. There are polaroid pictures of the cutouts on the jacket. There were 2 other spots on the jacket that tested postitive for blood. One had no DNA and the other was degraded to the point that only 3 markers registered. The blood that was identified as Danielle's matched all 13 markers after having been drycleaned. Drycleaning degrades DNA
The only thing found on the head board were some blue/gray fibers. No hair, no blood. Dusek said that Danielle was violently raped and her head banged against the headboard... Here is a link to a picture of the bed in the RV Link. She's 48 inches, he is 6' 2".
The single hair found in the RV was degraded.
Here's a site with other information. SND The Trial Evidence section has charts about what LE/Experts testified to. Also note that the hairs that had MitDNA do not list the lenght. Specific page references to transcripts are given.
All that said, there is speculation that there was more of a relationship between the convicted and Brenda than the public is aware of. One of my sources for that info, infact testified during the penalty phase. There's much more to this sordid story.
