Final answer:
The statement that crime scene technicians must collect evidence without altering the scene is true; it's vital for ensuring an accurate investigation and legal process.
Step-by-step explanation:
It is indeed the responsibility of the crime scene technician to collect the evidence without altering the crime scene. This statement is true. Preserving the integrity of the crime scene is crucial for a thorough and accurate investigation. Forensic science, which encompasses disciplines such as biology, chemistry, and biochemistry, relies on the meticulous collection and analysis of evidence. Forensic scientists and technicians work with various types of samples, including hair, blood, and other body fluids, and their work also involves processing DNA, which can be found in many different environments and materials. In this way, they can help piece together how a crime occurred, much like chemists use measurements to form theories about properties that are not directly observable.
