One of the best known fiber cases is the case of Wayne Williams and this is in Atlanta Georgia back at the end of the 70's and the beginning of the 80's. So starting in July 1979, the bodies of young black men were found dead in the woods of that area over a period of several months. It seemed likely that these murders were linked to each other. When the bodies were examined carefully, the investigators found fibers and they found the same fibers on different bodies. Identical yellow green or violet fibers in the clothing of the victims. Microscopic analysis showed that some of these fibers were quite unusual shapes and it took the police quite a while to track down the manufacturer. Now in early 1981 a newspaper picked up the story about the fibers and published it. Remember, the fibers were found in the clothing of the victims. After that newspaper article, further bodies were found but they were stripped naked and they'd been dumped in the river. So clearly the murderer read the newspaper. After the bodies were found in the river, the police started to watch the bridges. In May 2:00 am one morning, police officers watching one of these bridges heard a splash and on the bridge they found someone who they arrested and it was Wayne Williams. A couple of days later the body of the victim, a young man called Nathaniel Carter was found downstream, and yellow green fibers identical to those found on earlier victims were found on his body. Not in his clothes because he didn't have any, they were in his hair. Now the police have a suspect and they also have forensic evidence in these fibers. Naturally they searched Wayne Williams house and they found he had a yellow green bedroom carpet and the fibers from that carpet matched fibers found on 10 of the victims. Now you can make an argument here that Wayne Williams will not be the only person in Atlanta with that color or type of bedroom carpet. So, by now the police have been able to track down the manufacturer and they've been able to find out how much of this carpet had been sold. They could calculate that this carpet would be present in something like one home in each 8000 homes in the city of Atlanta. To put that in perspective at that time in Atlanta there was just over 600,000 homes. So the odds are quite good but not overwhelming. However, the police are not relying on a single kind of fiber because they also found violet fibers on 12 of the victims. These matched the fibers of a bedspread in Wayne Williams house. In addition to that, hairs from Wayne Williams dog were found on 11 of the victim's. Fibers from his car carpet were found on eight of the victims. So one single kind of fiber is not overwhelming evidence but when you take all this fiber evidence in its totality, it appears to be very strong and Wayne Williams was convicted and remains in prison to this day.
