Criminal Investigation and Forensics
Good Moring, I am expert witness VaShanti Lawrence. I was called to testify about hair. Also I am here to inform you about the forensic hair analysis and explain why it is considered calls evidence. I am going to prove that the suspect Colin Ross’s hair does match the hair found at the crime scene. This is a diagram of the basic structure of hair a hair from the crime scene, or one found on the victim, will be microscopically compared with a number of hair samples from the suspect. There are certain characteristics or traits to look for when analyzing macroscopically or microscopically. When analyzing the hair macroscopically you should look at the length, color, sheen, whether it’s wavy or straight, and the presence or absence of follicle tissue or not. Also you should try to determine the body location the hair came from. When analyzing hair microscopically you need to determine if it’s animal, vegetable, or synthetic in origin.
Hair is a charcter shared by all humans. Hair is a form of class evidence that had been useed in forensics analysis. Class evidence is evidence that can be linked to a group of people rather than individual evidence which can only be linked to one person.
