Adding a chemical/etc. to a surface to raise the fingerprint's visibility, which allows them to collect it using a tool (the tape-like thing) and bring to a lab.
"When it comes to a crime scene investigation, the events that take place are recognition of the crime scene, documentation of the scene, finding of the evidence, collection of the evidence, and finally analyzing all of the evidence collected."
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.
When a witness is taken back to the crime scene, it is known as a witness walkthrough or a witness reenactment. This can help refresh the witness's memory and provide investigators with valuable insights into the sequence of events.
A coroner at a crime scene assesses the body to determine the cause of death. They collect evidence, such as medical history and witness statements, to aid in their investigation. They may also take samples for toxicology tests and document injuries or wounds on the body.
Police and other crime investigation workers can take DNA from the scene of the murder (or other crime) and check it with databases of other DNA samples and match it to a person(s) and then they have their suspect(s).
CSI technicians use powder or chemical solutions to make fingerprints visible on surfaces. They carefully lift the prints using tape or specialized tools without smudging them. The lifted prints are then analyzed and compared to known prints in databases to identify potential suspects.
If a crime is committed, and fingerprints are part of the evidence gathered by the forensics team in a police department, they are first run through their database to see if they match anybody already in the system. If not, then these services take prints of suspects and attempt to match them to those from the crime scene
The name of the job where you would take DNA from a crime scene is called a Crime Scene Investigator.
The scene of a crime in the first instance is usually investigated by a constable who has responded to a call to attend the scene. His job is to take down details of the crime and statements from witnesses. It is also his job to preserve the crime scene until the Scenes of Crime Officer (SOCO) arrives to take over the investigation.
forensic investigators
yes your finger prints never change. even if they take your prints when your were 1, then they take them when your are 100, it would be the same.
The advantages of using a crime scene investigator is that they can use their expertise and experience to determine what took place at a crime scene. However, without solid evidence most cases cannot just take the word of the crime scene investigator.
first you go the crime scene. second you take notes about the crime scene third you dust around for fingerprints, gunshot residue etc fourth you interview the bystanders and witnesses, record all their comments fifth you take pictures of the crime scene and finally you release the crime scene tot he public with a statement idk if it is correct but it seems pretty real
When you need to find out more about taking a crime scene investigator test, I suggest you take a look at one of the online universities. They will list the options including the costs involved and the locations where the crime scene investigator test can be taken.
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.
CSI (Crime Scene Investigation) agents take pieces of evidence from a crime scene (anything from clothes and undergarments or pictures to various weapons) and subject them to a variety of chemical, physical and analytical tests to see know the who's, what's, where's and why's of that crime scene.
