Each of these sections can be subdivided into smaller sections for smaller teams to search thoroughly. D)Search method that employs two people performing line searches that originate from adjacent corners and form perpendicular lines E)Search method in which the investigator moves in an inward spiral from the boundary to the center of the scene or in an outward spiral from the center to the boundary of a scene F)Search method employed by several people moving from the boundary straight toward the center of the scene (inwarD)or from the center straight to the boundary (outward) G)Search method used by one or two investigators by walking in straight lines across the crime scene H)A precise rendering of the crime scene, usually drawn to scale I)A list of all people who came into possession of an item of evidence J)Physical evidence whose origin is known, such as blood or hair from a suspect, that can be compared to crime scene evidence K)The initial survey of the crime scene carried out by the lead investigator where he or she will gain an overview of the scene in order to formulate a plan for processing the scene L)Any object that can establish that a crime has or has not been committed or can link a crime and its victim or its perpetrator M)Uncontaminated surface material close to an area where physical evidence has been deposited -Spiral search
