A Denver TV station is reporting that a DNA sample taken from John Mark Karr doesn’t match the DNA found in the underwear of the late JonBenet Ramsey.

Not only does this mean that JonBenet’s killer is still at large, but also has to be considered a massive blow to the career prospects of Will Arnett (above), who had to be first in line to play Karr in the inevitable made for television exploi-drama.
