people can get dirt or move them which contaminates them so they can't really find out things from the fibres then. but if you look on websites you can find out.
no
so that no evedence is contaminated or removed
So they can better determine the area of the crime scene. Also to keep onlooking citizens out of the crime scene so it is not contaminated.
Forensic technicians and crime scene investigators are responsible for collecting physical evidence, such as dried blood and fibers, at a crime scene. They follow strict protocols to properly document, collect, and preserve evidence for analysis in the laboratory.
To prevent the contamination of any evidence possibly left at the scene.
its gauze and gauze hahha LOL
Macroscopic scene - the "large view" of a crime scene, including things such as locations, the victim's body, cars, and buildings. Microscopic scene - a crime scene viewed in terms of specific objects and pieces of evidence associated with the crime, such as knives, guns, hairs, fibers, and biological fluids.
Securing a crime scene is crucial to preserve evidence, prevent tampering, and protect the integrity of the investigation. It helps ensure that clues and information are not contaminated, lost, or destroyed, which is vital for solving the crime and holding perpetrators accountable.
Fibers found at a crime scene can provide valuable information such as the type of material, color, and potentially where it came from. By analyzing fibers, investigators can connect suspects to crime scenes or link different crime scenes together. This evidence can help establish a timeline of events and create a stronger case in court.
"Preserve the integrity of the crime scene." This phrase emphasizes the importance of securing and protecting the area where a crime has occurred to ensure that evidence is not contaminated or tampered with, allowing for a thorough investigation to take place.
Fibers can have probative value in forensic investigations because they can be transferred between people and objects, connecting them to a specific location or individual. By analyzing the physical and chemical characteristics of fibers, forensic experts can provide evidence to help link a suspect to a crime scene or victim. Fibers can be compared and matched to those found on a suspect's clothing or at a crime scene, strengthening the case against them.
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.
