Hair found at a crime scene contains DNA, which can be compared to a suspect's or victim's DNA to establish a link. Hair also has unique characteristics like color, length, and treatment, which can be used as evidence in investigations. Analyzing hair evidence can help to identify individuals present at the crime scene.
A rough crime scene sketch is typically done before evidence is collected. This preliminary sketch helps document the layout of the scene, including the location of items like weapons, bodies, and other important details for investigative purposes. It is not meant to be precise, but rather to provide a general overview of the scene.
The police, criminal investigators, forensic scientists, and/or FBI collect physical evidence, which is evidence at the crime scene. They also take photographs at the crime scene and take notes (like to say what time and location the incident happened), and they also do sketches on the crime scene. They draw out two sketches--one is called the rough sketch, which is drawn at the scene. The finished sketch is the sketch drawn after being at the crime scene. Finished sketches include measurements, precise locations, and other things that will help them solve the crime scene.

Crime scene investigators begin by having the scene of the crime secured. They must then take photographs of the crime scene, take notes on important pieces of information (such as posistion of a victim, presence of bruises or swelling), and identify items that need further testing in the lab. A crucial part of processing a scene is ensuring that evidence is not altered or contaminated. Failure to do so could result in all evidence being discarded.
