Technician Module 2 Unit 7 Slide 5

Student Performance Objectives

• 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 6

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 evidence in the hot zone following scene security measures and safety procedures in coordination with the incident commander.

Technician Module 2 Unit 7 Slide 7

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 8

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 9

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 10

Recognition of Criminal Activity

WMD Techs should follow departmental procedures for requesting law

enforcement assistance in handling and securing suspicious packages or

suspicious persons.

WMD Crime Scene Response

• Assignments

• Recognition

• Detection

• Self Protection

• Scene Security

• Notification

• Protect the Scene

Technician Module 2 Unit 7 Slide 12

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 13

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 14

Evidence Collection

• Physical EvidenceRIP – Recognized, Identified, Preserved

• Testimonial Evidence

Technician Module 2 Unit 7 Slide 15

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 16

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 17

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 18

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 19

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 20

DO NOT LEAVE EVIDENCE UNATTENDED!

Technician Module 2 Unit 7 Slide 21

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 22

Federal Statues

18 USC 2332a: Use of Weapons of Mass Destruction

18 USC 175: Prohibitions with Respect to Biological Weapons

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 24

FBI 12 Step Evidence Collection

Step 1 – Preparation

Preparation for the collection of evidence begins before the incident.

Technician Module 2 Unit 7 Slide 25

Step 2 – Approach the Scene

Emergency responders must consider personal safety and be mentally

prepared while approaching the scene.

Technician Module 2 Unit 7 Slide 26

FBI 12 Step Evidence Collection

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.
