The Technical Hazards Response Unit (THRU) is responsible for protecting over 1,800 men and women in the Laboratory Division’s Forensic Response Portfolio by providing on-site expertise in health and safety matters, paramedic medical care, complex evidence access, and operational logistics, as well as delivering accredited health and safety training. The unit manages all safety equipment utilized by the field Evidence Response Teams (ERTs) and Hazardous Evidence Response Teams (HERTs), as well as the Laboratory Division’s regional response infrastructure.

What they do:
When the FBI’s forensic responders encounter complex, high-hazard crime scenes, they provide the health and safety, evidence access, and logistical support necessary for these responders to operate in a variety of hazardous environments.

The unit also supports other evidence collection hazards, such as treacherous or physically inaccessible crime scenes, including those located in high-altitude environments or amid rocky or rough terrain. They also support the Laboratory Shooting Reconstruction Team and, when necessary, transport hazardous evidence from crime scenes or between partner laboratories. THRU personnel develop and instruct both FBI and state and local public safety personnel in specialized training. This includes courses that are Federal Law Enforcement Training Board-accredited and meet nationally recognized professional standards. On average, their training personnel support 70 courses annually, through which approximately 1,300 students receive specialized training.

The mission of the Scientific Response and Analysis Unit is to provide scientific, technical, and forensic support to FBI criminal and intelligence investigations involving chemical, biological, radiological, and nuclear materials, including their actual or threatened use as weapons. This is accomplished by developing, maintaining, and executing the FBI’s ability to evaluate, collect, examine, and analyze materials and related evidence.
Team:
Consists of two elements: Response and Analysis. Each has chemical, biological, and radiological/nuclear subject matter experts supported by operations research analysts, quality assurance specialists, management and program analysts, and a logistics management specialist.
What they do:
Provides end-to-end case support, crime scene processing and collections, evidence examination, and courtroom testimony regarding:

Chemical threats, including chemical warfare agents, such as nerve, blood, or blister agents.

Biological threats, including toxins and microbial agents, such as bacteria, viruses, and fungi that can cause disease in humans, animals, and plants.

Radiological/nuclear threats, addressing radiological and nuclear materials and associated devices, both intact and post detonation/dispersion.

Specialty examinations, such as:

Carbon-14 age dating of human remains

Plant, animal, insect, and seed identification

Genetically modified organisms

The team:
Photographic Operations consists of a supervisory photographer, along with scientific and technical photographers, providing on-call 24/7/365 response, site surveys, aerial missions, and equipment procurement and repair.
Photographic Operations:
Highly-trained scientific and technical photographers provide aerial photography; aerial mapping; operational site surveys to include special events; venue photography; high-resolution digital still photography; and 360 spherical imaging using both digital video and digital still photographic equipment. Scientific and technical photographers capture detailed and accurate photographic imagery for site documentation of crime scenes, bullet trajectory analysis, accident reconstruction, and evidentiary photography. FBI crime scenes are coordinated with Evidence Response Teams.
Field Photography Program:
Photographic Operations manages the FBI Field Photography Program, supporting field photographic personnel with photographic policies; installation of photographic equipment; coordination of equipment purchases and repairs; and the transition of field offices to newly adopted equipment and photographic techniques. In addition, OPU holds an annual field photography conference.
Photographic Services:
Photographic Operations provides services supporting the FBI operational site survey mission, aerial photography program, and crime scene survey and documentation. Photographic imagery collected for a site survey package in conjunction with the operational site survey mission can assist weapons of mass destruction and hazardous materials responders, SWAT teams, the Hostage Rescue Team, and command post decision makers by providing detailed venue information in an all-inclusive pre-surveyed and mapped scene.

Their mission is to provide hazardous and traditional evidence collection Capabilities to FBI field evidence response teams, Hazardous Evidence Response Teams, Hazardous Evidence Response Components, Underwater Search and Evidence Response Teams, and law enforcement partners by offering forensic training, resources, and expertise in support of the FBI’s investigative priorities.

The Program
The program supports teams in all 56 FBI field offices. They have to operate at an exceptional level of competence to make certain that evidence is collected in the correct manner so it can be introduced in courts.

The Team
The team is composed of special agents, forensic canine consultants, operation specialist, logistics specialist, and management and program analysts.

What do they do?
Training:

Provides basic forensic evidence preservation and collection training to new agents.

Coordination and Response:

Provides crime scene supplies and equipment, on scene support, and coordination for response to national and international special events and major crime scenes.

Underwater Evidence Program:

Composed of trained drivers capable of using sophisticated equipment underwater for searches to locate and recover evidence and human remains.

Forensic Canine Program:

Established to leverage scientifically based methods and canine behavioral applications of forensic detector dogs to assist federal, state, and local law enforcement agencies.

Hazardous Evidence Response Team Program:

This program provides support to the U.S. government’s response to incidents and threats involving weapons of mass destruction. HERTs support investigations of terrorism and the criminal use of chemical, biological, radiological, or nuclear materials. The program provides training, leadership, and subject-matter experts in hazardous evidence collection, crime scene management, and the processing of forensic evidence in CBRN crime scenes.
