The Atlanta Child Murders
Atlanta: black boys are murdered Similar fibers are found on the bodies When this is revealed, bodies start being dumped in water
Stopped by police on a bridge Said he was at a club, but no one saw him there Two days later a body appears downstream
Serial killers usually are… White Male Middle-aged Heterosexual
Wayne Williams was… A young black man—not a typical serial killer
BUT … This case pioneered the use of fiber evidence.
Key Fiber Evidence Avocado carpet fibers matching those in Williams’ home Purple carpet fibers matching those in Williams’ car
These two fibers were found on almost all the bodies. Many also had dog hairs, blanket fibers, etc. that also matched items in Williams home.
Because 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.
Probabilities House carpet1 in 5000 Car carpet1 in 1800
Overall probability … 5000 X 1800 = 9,000,000 … about 1 in 9 million
There are about 2 million people in metro Atlanta, so it is VERY unlikely the murderer was someone else.
Williams was convicted and sentenced to two life terms in prison.
Since his conviction there have been numerous appeals and re-investigations, most recently in May, Each time, the evidence was found convincing.
After Williams was taken into custody, the murders stopped.
