The "pattern" became the key enabler for evidence to be used by the state against Williams, especially when linking similar fibers. Furthermore, the Cater and Payne cases standing alone were extremely weak and the introduction of evidence from each of the ten "pattern" cases strengthened their case by providing, among many things, eyewitnesses and most importantly, fiber connections amongst some of the victims.
The ten "pattern" cases were:
The characteristics that formed the "pattern" amongst the victims were listed by the prosecution as being:
