within the police files saved by the hampshire police society from destruction, there is an item thatgay. her hair brush. and on it, some very obvious strands of hair. could these hold genetic information about her health? after a lot of research, i managed to track down one of the world's leading organisations for genetic examinations. based in the united states, they are the people who could tell me what secrets the hair on the brush could be holding. what can we actually get from the hair, bearing in mind it is 70 years old? after 70 years, and particularly on hair, the dna information that you would acquire would be mitochondrial dna information. unfortunately, it would not have information, really, relating to a disease state in your victim. it is very frustrating. this actually belonged to gay gibson. it hasn't been back in the great hall since the events of march 19118. and it seems the technology isn't practical enough to tell us what may live within the actual strands and follicles that sit upon the brush. but maybe one day it can give us a true picture of gay gibson's health
