The remains  of the hairs remain in the evidence locker, in a red
Petri dish.  The container bears the required chain of custody
markings.  One of the dates is some months before the second
trial.

Approaching the second trial, DNA testing had improved.  By
late 2007, more alleles could be tested, so instead of 7.5 million
to one, it might be a 15 or 20 million to one result.  Or it would
almost certainly exclude Moore, if it really wasn't his pubic hair
with Karen's blood on it.

The prosecution never had the DNA retested.  We would know
if they had, since prosecutors are required to provide that
evidence to the defense, and to the Court.  The defense, on the
other hand, isn't required to provide DNA results to anyone
except the Judge.  In such circumstances, the Judge restricts the
defense lawyers' ability to challenge the prosecution's DNA
evidence.  

In the second and third trials, in a DNA case, Daniel Moore's
lawyers offered no DNA testimony in his defense.
Moore left two pubic hairs in the crime scene, one on the bed
and the other in a bloody wash cloth. Mitochondrial DNA testing
of each hair gave odds of 500 to 1 that each belonged to Moore.  
Nuclear DNA testing of an attached
skin tagt matched Moore
with odds of 7.5 million to one.  It is the most damaging and
most conclusive evidence possible of his guilt--his pubic hair in
the crime scene with Karen's blood on it.  The hairs were
collected weeks before Moore confessed involvement to his
uncle.  They have remained under secure chain-of-custody since
the night of the murder.
