Steve Thomas said on Larry King Aired May 31, 2000 - 9:00 p.m. ET "......Patsy cannot be convicted because of some reasonable doubt, but an intruder cannot be convicted either because of the same reasonable doubt. This case requires a confession"
Patsy responded that "It requires DNA identification."
This exchange clearly shows two mindsets regarding the Jonbenet case. The Ramsey camp were pushing for a case resting on dna. Steve Thomas, who felt Patsy killed JonBenet and that John Ramsey wasn't involved, felt only a confession would solve the case. In his views, the dna found on the underwear (which as of 2000 was all the police authorities knew) could be touch dna from a multitude of sources i.e factory workers who handle clothes etc.
Thus, the new findings in DNA are signalled by the Ramseys as evidence of an intruder -- how can foreign dna, from separate items of clothing possible match etc. However, if UKGuy is correct in what he has stated then the dna being not 'mixed' with Jonbenet's blood could still be 'touch' dna.It is plausible that the dna from the longjohns that supposedly matched that found in the underwear is a result of contamination after the crime. For MurriFlower, note that I'm saying it is possible and that it is only speculation.
