  62. Do not attempt to reconstruct the items
    or process latent prints from the pieces before
    1. Wear gloves to avoid contaminating the area with your own fingerprints. Be careful not to wipe possible
    prints off the surface.
    2. Hold a flashlight at an angle, and look for obvious signs of a latent print.
    3. Take your brush and lightly dab into the powder once you find a target area.
    4. Tap and twirl the excess powder off the brush in the jar of powder. Use it sparingly because it tends to
    get on everything. It is better to use too little than too much.
    5. Lightly brush from side to side, or swirl the brush, on the target area. If the powder adhered to the print
    is too thick, brush off the excess powder with a clean brush and adjust the amount of powder.
    6. When you find a print, apply the tape in the following manner:
    a. Place a suitable fingerprint card on a flat surface nearby so that it is ready for the print you lift with
    the tape.
    b. Turn under the end of the lifting tape to form a tab.
    c. Extend the tape to a distance long enough to cover the print.
    d. Place the rolled end of the tape just above the latent print, but keep it off the print.
    e. Make sure that you do not trap foreign matter or air bubbles under the tape.
    f. Smooth from the tabbed end of the tape back toward the rolled end or vice versa. Use your finger,
    pen, or another object to smooth out the tape and release any trapped air. It is the same basic
    process as putting a decal on a window. With time and practice, you will develop your own
    technique for applying the tape.
    7. Slowly lift the tape containing the developed prints from both ends, being careful not to touch the tape
    to another surface, such as your gloves.
    8. Carefully place the tape on the fingerprint card in the same way that you placed the tape over the latent
    print. Place the print in the designated place on the correct side of the card.
    9. On the back of the fingerprint print card, record the date, case number, the location within the crime
    scene where you retrieved the fingerprint and any other information your agency's policies and
    procedures require. Be careful not to damage the print.
    10. Follow your agency policies and procedures to submit print evidence.

          

  63. Microanalysisis the process of microscopically analyzing trace evidence, such as paint, glass, and cloth fibers, to determine a possible source or origin. Microanalysis can

  72. Dislodge the magazine andare transferred from the friction ridges on fingers by a FOREIGN SUBSTANCE (not a body residue), like blood, paint, or dirt, and are
    readily visible.

    ammunition in a
    separate container, then place them both in the firearm or evidence box.

    tool.

          

  77. Sometimes, soil from a crime scene attaches to a suspect's or victim's clothing, shoes, tires, or other objects, and the person transports it todetermine what evidence at the scene belongs to the criminal and not to the victims or witnesses.

          

  78. The most common way to process latent fingerprints is bydusting them with one of several types of powder, which
    develops the print and makes it visible. Use a fine brush to apply dust to the surface on which someone placed a
    print. Lift a found print from its original surface with clear or frosted tape, then attach it to a small note card.

          

  79. The direction of force or the order in which glass is broken can determine on whichside of the glass the suspect stood, thus establishing the suspect's entry or exit path.

  82. Dr. Edmond Locard (1877-1966), a pioneer in forensic science, formulated the fundamental principle of forensic science:"Every contact leaves a trace." Referred to as
    Locard's Exchange Principle, this contends that everyone who enters a crime scene will both bring something into and take something from it.

    secretions, feces, or vomit

          

  84. • spiral search pattern:usually used outside by one person. The searcher begins
    at a certain point and walks in increasingly larger circles to the outermost boundary of the search area.

          

  85. A suspect does not have the right todamaged surface and submit it to the laboratory for comparison with the suspect's
    tool.

          

  86. Other pieces of evidence that may contain saliva, and require examination, arefingerprints, shoe prints, blood, fibers, hair, tool marks, paint scratches, broken glass,
    bodily fluids, controlled substances, electronics equipment and computers, firearms,
    broken or damaged materials, tire tracks, documents, and bones.
