Final answer:
The forensic detective used a zone search method by assigning each team member to search a different room in the house, ensuring a thorough review of each area. This methodical strategy is key for finding hidden evidence and includes examining furniture, floors, and secret compartments with tools such as needles and microscopes.
Step-by-step explanation:
The search method chosen by the forensic detective, where each person in the team is assigned to search a different room for evidence, is called a zone search strategy. This method is especially useful in structured environments such as houses or buildings. The goal is to comprehensively search each area or zone to prevent any evidence from being overlooked. By dividing the house into sections and assigning a team member to each, the detective ensures that each room is carefully and systematically examined.
In practice, this method might involve searching the entire building, room by room, examining the furniture, looking between the boards and the plates, and probing the beds and the bedclothes, as well as the curtains and carpets. A forensic detective also pays close attention to details that could conceal evidence, including secret drawers, spaces under the cushions, or areas beneath the carpets. These areas are scrutinized with precision, often with tools like fine needles and microscopes, as indicated by the references to the detailed examination of every particle of the premises.
Additionally, when enough clues and measurements are collected, similarly to chemists in a laboratory, detectives can piece together a theory of the crime, even if they were not present when the crime was committed. This methodical search can lead to the gathering of evidence, including DNA extraction, that can be crucial in solving the crime.
