What is Evidence?
There is physical evidence which is something that has shape and comes in any form. Physical evidence can be movable or immovable. Movable evidence includes guns, hair, fibers, blood on glass. Immovable evidence includes fingerprints, or shoe prints, or tire tracks. Identified evidence shares a common source, like fibers match a shirt, an unfired bullet matches to a box of ammo. Individualized evidence can be linked to a unique source.
Reflection: At the beginning I was worried about remembering all the terms. At the end if the unit I really knew my stuff and I enjoyed learning about everything. Something that stood out to me were blood spatter. I liked learning about the angle of the wound can be shown in how the blood is at the scene.

Criminals usually come for something but almost always leave a small piece of evidence behind.This is the principle that is called The Locard Exchange. Crimes are solved by using the necessary branches of forensics to “decode” a crime scene and gather the evidence they need to catch the criminal.
