11Because the carpet fibers were unusual colors,
the probability they would be on a body was quite
low.The probability they would appear together
was even lower.

13Probabilities
House carpet 1 in 5000
Car carpet 1 in 1800
14Overall probability 5000 X 1800 9,000,000
about 1 in 9 million
15There are about 2 million people in metro
Atlanta, so it is VERY unlikely the murderer was
someone else.
16Williams was convicted and sentenced to two life
terms in prison.
17Since his conviction there have been numerous
appeals and re-investigations, most recently in
May, 2005.Each time, the evidence was found
convincing.
18After Williams was taken into custody, the
murders stopped.
