Intro to Hair

Hello you fine jury before me <3 today i will be speaking on the topic of hair which many of you im assuming dont know all the technicalities of it and im here to change that. as a mega overview; its a class evidence piece unless found with more specific DNA such as the root of the hair.

Cuticle: the cuticle is basically the shape of the scale which you can see on the outside.

Cortex: The cortex is the thickness of the hair along with the actual feeling of the hair and its texture.

Medulla: is the pattern on the inside which can be difficult to actually see

Human VS Animal Hair

There are some key differences between human and animal; one example is how a human hair will always be amorphous scales on the outside. And the constant pattern inside of the hair will also tell you the ethnicity of the human in question.

And two general differences between that of a human hair and a animal is the scale shape and the texture of the hair. such as a blondes hair next to a hair from your cat. Its gonna be different

Cortex

1. in both hairsit seems to be constant, no big leaps of patches of baldness?

Medulla

The medulla is different from the hairs I think, the crime scene hair is much more thick then the suspects hair, it almost looks like a animal hair.

Roots

daniel_harbour — 2019-08-20 17:03:51 UTC

The crime scene hair had been ripped from the suspect it looks and the suspects hair looks as if it fell out with time.

Anagen: this is when its growing and is nice and rooted into your dome so these guys arent going anywhere.

catagen: this is the phase it spends most of the time, its not falling out yet if it was tugged there is a chance its coming out.

Telogen: This is when the hair is pushed up and out to make way for new hair to grow.

The root at the crime scene is a unique one because it shows there was a struggle at the scene because the root exhibits a sign of distress within the victim

Distal

the crime scene hair was pulled out but the end is in perfect condition while the suspects hair has been torn and or cut at some point in the past.

Final Analysis

daniel_harbour — 2019-08-20 17:15:01 UTC

I have no clue to be frank with you. But the suspects hair i feel like does nit sync up with the crime scene hair. its too different and to many variables left to the unknown so im going to say the suspect is innocent.
