I believe it is. It will show DNA to help find evidence and suspects to close the case!

Pollen at a crime scene can be collected using techniques like tape-lifting, vacuuming, or swabbing. The collected samples can then be analyzed under a microscope to identify the types of pollen present, which can help link suspects or objects to the scene.
finger prints
"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."
Because in every crime something is either taken and/or left behind by the culprit, therefore connecting them to the scene.
It is called "processing"
Fingerprints left at a crime scene are called latent prints. These prints can be collected and used as evidence to help identify suspects and link them to the crime.
No, crime scene units are responsible for collecting and analyzing physical evidence at crime scenes. It is law enforcement agencies that investigate crimes, catch offenders, and make arrests based on the evidence collected by crime scene units.
Fluids (of all types) are collected and sealed in air-tight vials or small bottles/jars.
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.
Potential sources of DNA at a crime scene could include blood, saliva, skin cells, hair follicles, semen, and other bodily fluids. DNA can also be extracted from items that the perpetrator may have touched, such as weapons or clothing. Additionally, trace DNA left behind on surfaces or objects could be collected as evidence.
its evidence. it doesn't mean everything but what is collected during a criminal investigation that helps prove the suspect/prosecutor committed the crime. Much of it is collected at the crime scene, if there is one.
A crime scene investigator collects physical evidence from crime scenes, documents and preserves it for analysis. A crime scene analyst, on the other hand, works in a lab to analyze evidence collected by investigators, such as DNA, fingerprints, and ballistics, to provide conclusions and insights to aid in investigations.
