It is a process that keeps track of how evidence moves and writes down information about each person who touched it, the date and time it was collected or moved, and the reason for the move. Maintaining the integrity and admissibility of evidence is important.
Typically, the complainant is the one who makes a statement alleging that another individual committed a crime.
Physical evidence includes physical items like fibers, biological material, and latent fingerprints. Physical evidence is anything that can link a victim or suspect to the scene of a crime. The DNA in biological evidence is not always visible to the naked eye.
A witness is someone who knows something important about a crime or other event. They may have witnessed or heard the crime or had crucial information about the defendant.
The spiral search pattern includes making circular motions (either inside or outward) throughout the area in question. It is a distinct and specialized crime scene search pattern. It is often used at crime scenes that are small or crowded, like small, fenced yards or small rooms. Investigators begin at one end of the search area and go forward in the same direction to conduct the approach. People often use spiral searches to find a certain item at a crime scene.
With close-up photography, you can show details about the evidence. A close-up shot is a picture or film shot made at close range of a subject or object in order to reveal better detail.
Trace evidence is conveyed when two items come into contact or when small particles are dispersed by an action or movement.
"Every contact leaves a trace" is a well-known forensics principle, also called Locard's exchange principle after the criminologist who came up with it. The theory says that every criminal leaves something behind at the scene of the crime and takes something away from the scene of the crime.
It is commonly considered of as evidence to support a belief, conclusion, experiments, or other secondary sources of knowledge. Providing evidence to back up an argument necessitates the audience using prior information and thinking more thoroughly about it.
Plastic prints are made when you touch something soft and malleable, like wax or fresh paint. They may also be seen with the naked eye.
DNA is a type of physical evidence that can be found in biological evidence. Biological evidence is not always evident to the naked eye. DNA testing has added to the types of biological evidence that can be useful.
A patent print is just a print that can be seen. Some imaging is needed to preserve many of these prints, which are fully apparent to the naked eye.
Private property refers to property owned by private parties, i.e., anyone or anything other than the government. Real estate, buildings, things, and intellectual property can all be considered private property (copyright, patent, trademark, and trade secrets).
Zone Method: To search a scene, divide it into four parts. The search can be done by the investigator alone or with the help of other people. The people searching each quadrant can do it in any way they want. This strategy works effectively on huge areas.
This method only works for large outdoor scenes, such as fields, deserts, and other open areas. It's like the zonal method, but the wheel is split into different sections based on how big the crime scene is.
Elimination prints are a common part of an investigation. Getting fingerprints from anyone who has a good reason for why their prints were found at the scene helps get rid of their prints from the scene. Knowing what prints belong to which people speeds up the investigation process because those prints can be "eliminated" from other prints that don't belong to "authorized" people.
