OK. I hear you. How do you know they didn't have a sample ?
They found Danielle's underwear with a stain in the crotch. That was 02/02,I believe. They took a sample. It is what was used later to compare to the lapel of the green jacket, and LO and BEHOLD, it came back A PERFECT MATCH. Not good, average, BUT PERFECT.
They had a supposed blood stain on the PJ's that were lying there also.
You know, the one's that Danielle hadn't worn. THey were just lying there inside out, with a bloodstain on the ankle area. (when Feldman tried to ask about Danielle having a scrape on her ankle, DUSEK objected and MUDD sustained it. WHY?) The LE's say that the DNA test of that stain didn't have Danielle's DNA. (well whose was it?)
REASON: we aren't supposed to know that those are the PJ's she wore. That she didn't have them on when she disappeared. If they admitted it was Danielle's blood, it would have damaged their case and made Damon/Brenda out to be bigger liars.
The shirt cuff, of both the pj's and purple shirt....not sure why Feldman was saying ankle but it may have been why he was objected.
