If no crime scene analysis is carried out with the death investigation, what types of evidence may never be located and recovered?

________ can occur by introducing foreign DNA through coughing or sneezing onto evidence during the collection procedure.

Which crime-scene search pattern would absolutely require more than one investigator?

The integrity of evidence is best maintained when the item is kept in its ________ condition as found at the crime scene.

Match the word in Column 1 to its definition in Column 2. Each answer can only be used once. A)A swab of the inner portion of the cheek B)A draft representation of all essential information and measurements at a crime scene C)Search method in which the crime scene is divided into smaller sections and team members are assigned to search each section. 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 -Grid search

Which search pattern would be best suited for a crime scene where many investigators are available to search a large area?

Videos of the crime scene:

The officer charged with protecting the scene has the authority to exclude fellow officers.

It is not necessary to package evidence in separate containers.

List two possible consequences of failure to protect a crime scene properly.

Investigators should collect possible carriers of trace evidence which may include:

A ________ sketch is a draft representation of all essential information and measurements at a crime scene.

The main disadvantage of digital photography for recording crime scenes is that digital photographs can be easily manipulated by using computer software.

When a vehicle is involved in a crime, investigators should pay particular attention to signs of a(n)________ of evidence between the car and the victim.

A(n)________ control consists of uncontaminated surface material close to an area where physical evidence has been deposited.

When biological samples of unknown origin are discovered at a crime scene, investigators should:

The search pattern that employs two people performing line searches that originate from adjacent corners is:

To formulate a successful strategy for recovering relevant physical evidence at crime scenes, the investigator must ultimately rely on:
