    broken into residence and scribed into her
    television. He also told her that he loved her
  • Mrs. Jones and husband go to dinner out of town.
  • While gone, their residence was burglarized with
    several items taken (gun, money and drugs). Also
    it is believed that the items taken from the
    other burglary were also taken from Mrs. Jones
    residence

    stolen items including items taken from other
    burglary

37

Worked cases
  • I worked over 100 fire scenes from 09/01/2005 to
    08/31/2006.
  • We do not do full blown investigations
  • We are only mainly for the fire scene exam.
  • With being on over 100 fire scenes, the travel
    involved, the care for the canine, there is not
    much time for anything else.

77
How the canine works
  • The canine is purchased overseas
  • We get them from a vender in Alabama
  • The canine is trained on odor for 5 weeks before
    we get it
  • The canine is placed with the handler and they
    train for an additional 5 weeks

78
How the canine works
  • The canine uses its nose.
  • The canine smells in parts per million and
    billion.
  • The canine works for the reward.
  • The canine has a passive alert. Sit and stair.
  • The canine knows when he finds the source of the
    odor its toy will pop out.

79
How the canine works
  • There are four drives prevalent in SFMO canines
  • Hunt
  • Air scent
  • Retrieve
  • Prey

80
How the canine works
  • There are many uses for the canine in today's
    work and play environment

82
How the canine works
  • Work dogs
  • Pet dogs
  • There is a difference

83
How the canine works
  • The work dog works. That is all he wants to do.
    He wants to find the odor and get his toy and
    play.
  • He is born, bread and raised this way.
  • However he will still be just a dog when he wants
    to.

84
What the K-9 team can do for you
  • The team can assist you with the fire scene exam.
  • Safety
  • Diagram
  • Documentation
  • On scene interview
  • Fire debris removal
  • Evidence location and collection.

85
What the K-9 team can do for you
  • Fire scene examinations should not be undertaken
    alone. A minimum of two individuals should be
    present to ensure that assistance is at hand if
    an investigator should become trapped or injured.
    If it is impossible for the investigator to be
    accompanied, he or she should at least notify a
    responsible person of where the investigator will
    be and of when he or she can reasonably be
    expected to return. 

86
What the K-9 team can do for you
  • The main reason for the K-9 team on a fire scene
    is evidence location and collection.
  • Some handlers will tell you where to pull the
    sample.
  • Some will pull the sample and send it to the lab
    themselves.

87
What the K-9 team can do for you
  • When a canine/handler team is used to detect
    possible evidence of accelerant use, the handler
    should be allowed to decide what areas (if any)
    of a building or site to examine. Prior to any
    search, the handler should carefully evaluate the
    site for safety and health risks such as
    collapse, falling, toxic materials, residual
    heat, and vapors and should be the final arbiter
    of whether the canine is allowed to search.

88
What the K-9 team can do for you
  • It should also be the handlers decision whether
    to search all of a building or site, even areas
    not involved in the fire. The canine/handler team
    can assist with the examination of debris (loose
    or packaged) removed from the immediate scene as
    a screening step to confirm whether the
    appropriate debris has been recovered for
    laboratory analysis. 

89
What the K-9 team can do for you
  • Properly trained and validated ignitable liquid
    detection canine/handler teams have proven their
    ability to improve fire investigations by
    assisting in the location and collection of
    samples for laboratory analysis for the presence
    of ignitable liquids. The proper use of detection
    canines is to assist with the location and
    selection of samples. 

90
What the K-9 team can do for you
  • In order for the presence or absence of an
    ignitable liquid to be scientifically confirmed
    in a sample, that sample should be analyzed by a
    laboratory. Any canine alert not confirmed by
    laboratory analysis should not be considered
    validated. 

91
What the K-9 team can do for you
  • Research has shown that canines have responded or
    have been alerted to pyrolysis products that are
    not produced by an ignitable liquid and have not
    always responded when an ignitable liquid
    accelerant was known to be present. If an
    investigator feels that there are indicators of
    an accelerant, samples should be taken even in
    the absence of a canine alert. 

92
What the K-9 team can do for you
  • The canine olfactory system is believed capable
    of detecting gasoline at concentrations below
    those normally cited for laboratory methods. The
    detection limit, however, is not the sole
    criterion or even the most important criterion
    for any forensic technique. Specificity, the
    ability to distinguish between ignitable liquids
    and background materials, is even more important
    than sensitivity for detection of any ignitable
    liquid residues.

93
What the K-9 team can do for you
  • Unlike explosive- or drug-detecting dogs, these
    canines are trained to detect substances that are
    common to our everyday environment. The
    techniques exist today for forensic laboratories
    to detect submicroliter quantities of ignitable
    liquids, but because these substances are
    intrinsic to our mechanized world, merely
    detecting such quantities is of limited
    evidential value. 

94
What the K-9 team can do for you
  • Current research does not indicate which
    individual chemical compounds or classes of
    chemical compounds are the key triggers for
    canine alerts. Research reveals that most classes
    of compounds contained in ignitable liquids may
    be produced from the burning of common synthetic
    materials.

95
What the K-9 team can do for you
  • The proper objective of the use of canine/handler
    teams is to assist with the selection of samples
    that have a higher probability of laboratory
    confirmation than samples selected without the
    canines assistance. 

96
What the K-9 team can do for you
  • Canine ignitable liquid detection should be used
    in conjunction with, and not in place of, the
    other fire investigation and analysis methods
    described in this guide. 

97
What the K-9 team can do for you
  • Location of evidence
  • Sometimes there will be an indication where we
    would not think to pull a sample
  • The K-9 will go to the strongest source of the
    odor
  • Contents legs at floor level
  • Door jambs and base plates
  • Under decks in the dirt

98
What the K-9 team can do for you
  • A quicker search, fewer and more accurate samples
  • Because the K-9 has a stronger sense of smell he
    will go to the odor
  • The Investigator may only look at the burn
    patterns and pull from experience
  • May pull more samples than is needed

99
Knowing when to call a K-9 Team
  • Get accurate information from the requestor
  • Contact the owner and find out what was in the
    structure.
  • Contact local Police

100
Knowing when to call a K-9 Team
  • The requestor will give you general knowledge
    about the fire
  • What type of structure and use
  • Date and time
  • Weather conditions
  • Utilities
  • Any suspicious activity

101
Knowing when to call a K-9 Team
  • The owner can give you information about what was
    in the structure.
  • Storage of ignitable liquids
  • Chemicals

102
Knowing when to call a K-9 Team
  • The Police can give you history about the address
  • Calls for service
  • Type of calls
  • Drug activity
  • Disturbances
  • Burglaries
  • Other fires in the area

103
Knowing what to do before the K-9 team arrives
  • Do what you need to do to prepare for your
    examination.
  • Exterior photos
  • Diagram
  • Interviews
