Williams+Case+Study+Questions+CK

1.)  The use of fiber evidence in the Williams case differed significantly from its use in previous cases in the respects that  a.   It was a make or break situation.  b.   It convicted a suspect and narrowed own the options. They had a person in mind since they saw him on the bridge and the matching fiber further helped solidify the progress.  2.)   They learned that the fibers on the bodies were rare, as there were not a lot of matching ones circulating in the area. They learned that they had to get specific as to the type; it would not be generic. The significance of their discoveries is that they now had access to information that allowed them to narrow down the possible suspects. All of the fibers could be traced back to a single source. 3.)  The information of the source of the fibers would give them access to manufacturer information, which would give way to retailers, which would give way to customers. They could then see if any of the buyers of the carpet matched their profile.  4.)   First, they matched the fibers from the body to the house, then used the information from the manufacturer and matched him to the profile.The company had a specific line of carpet that the fibers could be matched to. 5.)  They used statistical probability to tie Williams to his victims, as well as the fact that the carpet was rare. Though the probability was rare, they applied the statistics to the profiles and progressed from that point.
