Translation of the body of text of page 5 as I read it to be
simply stated, the theory explains that the Hairs and fibers found on an individual are reflective of their most recent and immediate surroundings. This principle is particularly applicable to situations in which a body is in physical contact with an object such as a residential or automobile carpet. Based upon my review of the evidence, including crime scene photos, it is indisputable that Colette MacDonald's body was last in contact with with the shag rug in the master bedroom. Based upon my experience and training as a hair and fiber examiner, it is my opinion that rugs are conductive to the transfer and retention of foreign fibers. Further, since woolen fibers possess an outer layer of scales, they are among the fibers most readily transferable to surfaces such as rugs.
