I also posted links to two different MSM articles which reported that fast-tracked DNA in this case could be returned in two days. If LE traveled all the way to CO, they probably asked for DNs DNA to be fast-tracked. IMO, pinning the Delphi murders on DN is not gonna happen.
I agree with you, DN is in a lot of trouble in CO and may have even killed TW but I think that his DNA did not match the sample they have that they believe belongs to BG. Back to the drawing board as they say.
