Crime Scene Investigation Teams

When a serious crime occurs, it's not just one person who shows up to investigate. Crime scene investigators work as a coordinated team, each bringing specialised skills to identify, collect, and process crucial evidence.

The crime scene investigator is like the team captain, responsible for securing the area and documenting everything they find. They're the ones collecting physical evidence, obtaining warrants, and preparing those detailed reports that prosecutors will use in court. Think of them as the organisers who make sure nothing gets missed.

Forensic scientists work their magic back in the laboratory, running tests on everything from blood samples to mysterious substances. They use high-tech equipment like infrared and ultraviolet light to determine what materials are made of and whether specific substances are present. They can even reconstruct crime scenes using plaster casts of footprints or tyre tracks.

The crime scene photographer captures everything through the lens - and their photos often become the most powerful evidence in court. They document the initial scene, victims' wounds, and every piece of evidence before anything gets moved or disturbed.

Remember: Photography must happen first, before anyone starts collecting evidence, because you can never recreate the original crime scene exactly as it was found.

Evidence collectors specialise in the delicate work of lifting fingerprints and gathering DNA traces like blood and hair. Their job is absolutely crucial because if evidence gets contaminated or compromised, it becomes useless in court.

Finally, CSI technicians handle the paperwork and equipment maintenance that keeps everything running smoothly. They create diagrams, maintain evidence logs, and ensure all investigative equipment is clean and ready for the next case.
