• Recognize the importance of coordination with other
agencies on the scene in gathering evidence and
intelligence. Understand the importance of
development and sharing of the latest intelligence
that has been gathered from the scene, including
signs, symptoms, and treatment, as well as
information from interviews with victims and other
potentially contaminated individuals. Recognize that
this information should be shared with the emergency
medical manager, the on-scene incident commander
(or designee, or the leadership team under the
unified command), and the senior law enforcement
leadership at the scene.
Technician Module 2 Unit 7 Slide 5
Student Performance Objectives
• Know how to collect and forward intelligence
regarding potential terrorist/criminal actions involving
possible WMD agents or hazardous materials. Be
able to coordinate the gathering of such intelligence
from various sources that may be on the scene.
Forward this information to the HazMat manager and
the incident commander (or designee) at the scene.
• Be able to work with law enforcement to gather

measures and safety procedures in coordination with
the incident commander.
Technician Module 2 Unit 7 Slide 6
Crime Scene
A crime scene is a location where an
actual crime has taken place or there is a
possibility that a crime has taken place.
Technician Module 2 Unit 7 Slide 7
Criminal Investigation
Typical process whereby police are able
to link an offender to the crime is through
the use of investigation and finding of
evidence at the scene.
Technician Module 2 Unit 7 Slide 8
WMD Crime Scene
• Emergency responders should consider life safety as the first
priority.
• Every WMD crime scene is different and should be handled
accordingly.
• Initial response to a WMD crime scene may have very few
perimeters and be difficult to define.
• WMD crime scenes have the capability to cause mass casualties
and extraordinary damage or vice versa, small damage and few
casualties.
• Initial actions taken by responders at the scene by the emergency
responders are critical for the preservation of evidence.
• Once the crime scene has been established, law enforcement
should control ALL access to the and from the scene.
Technician Module 2 Unit 7 Slide 9
Recognition of Criminal
Activity
WMD Techs should follow departmental
procedures for requesting law
enforcement assistance in handling and
securing suspicious packages or
suspicious persons.

Scene Coordination
Responders should be able to recognize
the importance of coordination with other
agencies on the scene in gathering
evidence and intelligence.
Technician Module 2 Unit 7 Slide 12
Information Sharing
It is important of developing and sharing
of the latest intelligence that has been
gathered from the scene, including signs,
symptoms, and treatment, as well as
information from interviews with victims
and other potentially contaminated
individuals.
Technician Module 2 Unit 7 Slide 13
Evidence Collection
• Physical Evidence
RIP – Recognized, Identified, Preserved
• Testimonial Evidence
Technician Module 2 Unit 7 Slide 14
Documentary Evidence
Documentary evidence must be relevant
to the case before the court before it can
be admissible. In the case of writings, the
authenticity of the document is one aspect
of relevancy.
Technician Module 2 Unit 7 Slide 15
Discovery
Discovery is a pretrial procedure in
which one party gains information held
by the other party regarding the case
Technician Module 2 Unit 7 Slide 16
Chain of Custody
Chain if custody is the process that
begins once evidence is identified. The
best way to think about chain of custody
is to visualize a continuous loop of links
that connect together adding anyone to
the loop when the evidence changes
hands to another person.
Technician Module 2 Unit 7 Slide 17
TESTIMONY !
DO NOT RATIONALIZE ON THE STAND
DURING ANY TESTIMONY.
IF YOU DO NOT KNOW, SAY YOU DON’T
KNOW.
NEVER LIE !
Technician Module 2 Unit 7 Slide 18
Intelligence
• Recognize it as evidence
• Forward the information about the
intelligence to the supervisor
• Supervision verifies
• Supervision notifies command post
• Command post forwards to joint
operations center
Technician Module 2 Unit 7 Slide 19
DO NOT LEAVE EVIDENCE
UNATTENDED!

WMD Prosecution
All WMD crimes fall under the jurisdiction,
or the territorial range of authority and
control, of the Federal courts.
Technician Module 2 Unit 7 Slide 21

Technician Module 2 Unit 7 Slide 22
FBI 12 Step Evidence Collection
When Federal response teams arrive they
will most likely use the FBI’s Twelve-Step
Process of evidence collection. It is very
much so recommended that the WMD
Tech be familiar with this Twelve-Step
Process because it is a highly regarded
and tested method for the collection of
evidence.
Technician Module 2 Unit 7 Slide 23
FBI 12 Step Evidence Collection
Step 1 – Preparation
Preparation for the collection of evidence
begins before the incident.
Technician Module 2 Unit 7 Slide 24

Step 3 – Secure and Protect the Scene
A perimeter must be set up around, and
control zones established within, the
crime scene in order to have an
appropriate work environment.

Step 5 – Evaluate Physical Evidence
Possibilities
The team leader will determine what
types of evidence are most likely to be
encountered, and ensure that the
transient, volatile, or perishable evidence
is collected first.

Step 6 – Prepare Narrative Description
The narrative description begins as a
written document (it may be dictated) that
presents the scene in general text and
becomes more specific and detailed as
the investigation continues.

Step 8 – Prepare Diagram/Sketch of
Scene
An entry team member usually prepares
the sketches and diagrams concurrently
with other activities such as photography
and reconnaissance.
Technician Module 2 Unit 7 Slide 31
FBI 12 Step Evidence Collection
Step 9 – Conduct Detailed Search
The initial plan determines which items
constitute evidence and how they will be
collected.

FBI 12 Step Evidence Collection
Step 10 – Record and Collect Physical
Evidence
When potential evidence is discovered, it
is processed in a specific order from
handling fragile evidence to turning the
evidence over to the evidence custodian.
Technician Module 2 Unit 7 Slide 33
FBI 12 Step Evidence Collection
Step 11 – Conduct Final Survey
The final survey involves a review by all
team members to discover if anything has
been overlooked or if additional work is
needed.
