Final answer:

At a crime scene, police officers, CSIs, forensic scientists, medical examiners or forensic pathologists, forensic anthropologists, and detectives work as a team to collect evidence, analyze the crime, and solve the case.

Step-by-step explanation:

At a crime scene, a team of professionals work together to gather evidence and piece together what occurred. Among these are police officers, who secure the scene and collect initial statements, and crime scene investigators (CSIs), who meticulously document the scene and collect physical evidence such as fingerprints and footprints. Forensic scientists apply scientific techniques to analyze biological samples like hair, blood, and body fluids, and process DNA to link suspects to the crime or exonerate the innocent.

Medical examiners or forensic pathologists are responsible for examining deceased victims to determine causes of death. Forensic anthropologists may be called upon when dealing with human remains, to determine factors such as age, sex, and stature, and to help understand the circumstances surrounding the death. Lastly, detectives lead the investigation, interrogating suspects and piecing together the evidence to solve the crime.
