Crime scene investigators use techniques like powder dusting, cyanoacrylate fuming, or ninhydrin spraying to develop latent fingerprints at a crime scene. They then lift the developed prints using adhesive tape or specialized fingerprint lifting tools for analysis and comparison.
Police investigators require crime scene photos to be taken so that later on they can review the crime scene even if it was already cleaned. It occurs if someone wants to review old files and files an appeal.
The original location of a crime or accident is called the primary crime scene. This is where the incident first occurred and where evidence is typically found and collected by investigators to piece together what happened.
Objectivity in crime scene reconstruction is important because it helps ensure that investigators analyze evidence without bias or preconceived notions. By adhering to objectivity, investigators can focus on facts and evidence, leading to more accurate and reliable conclusions about what transpired at the crime scene. This ultimately helps in seeking justice and holding offenders accountable.
Forensic investigators use genetic markers that vary from person to person. Thus, if all of the genetic markers in the DNA from a crime scene are identical to the genetic markers in the DNA from one of the suspects, that is good evidence that the suspect and crime scene DNA came from the same individual.
Securing a crime scene is crucial to preserve evidence integrity and prevent contamination. It helps maintain the chain of custody, ensuring that evidence can be admissible in court. It also protects the safety of investigators and ensures a thorough and accurate investigation.
Crime scene investigators document and analyze information found at crime scenes.
Observation
The crime scene investigators use the biotechnology and genetis technology for solving their case. They collect every sample from the crime scene and perform the laboratory tests on it which gives them clue about what would have happened on the crime scene and then DNA and the fingerprints are used to prove the identity of the person associated with crime scene
