Roy Whiting, a 56-year-old mechanic, was imprisoned for life for the murder of 8-year-old Sarah Payne in 2000 after a single strand of hair found on his shoe allowed police to perform a full DNA comparison matching it to Sarah. Sarah was abducted and strangled to death while playing near her grandparents' home in England. This hair evidence was crucial as fibers from Sarah's blue dress could not be used for identification.
