Study Notes
Introduction to Criminal Investigation
- The objective of a criminal investigation is to gather evidence and identify the perpetrator of a crime
- A procedure for conducting an investigation will be discussed, including the main objectives and steps taken in a preliminary investigation
Types of Bombs
- Explosive Bomb: causes damage by fragmentation, heat, and blast wave
- Incendiary Bomb: constructed with flammable materials designed to produce a burning effect
Laws Pertaining to Arson and Explosives
- Arson (Class A, B, or C Felony): knowingly damaging a building or inhabitable structure by starting a fire or causing an explosion
- Knowingly burning or exploding (Class "D" Felony): knowingly damaging property of another by starting a fire or causing an explosion
- Reckless burning or exploding (Class "A" Misdemeanor): recklessly damaging or destroying a building or inhabitable structure of another by knowingly starting a fire or causing an explosion
- Negligent burning or exploding (Class "B" Misdemeanor): with criminal negligence causing damage to property of another by fire or explosion
- Causing catastrophe (Class "A" Felony): knowingly causing death or serious physical injury to ten or more people; or substantial damage to five or more buildings or inhabitable structures
- Possession, manufacture, transport, repair, or sale of certain weapons prohibited (Class "C" Felony)
- Bombing and other explosive matter upon bus or near bus terminal (Class "A" Felony)
- False Bomb Report (Class "A" Misdemeanor): knowingly making or causing to be made a false report to any person that a bomb or other explosive has been placed in a public or private place or vehicle
Bomb Threat Response Procedures
- Turn radio off when nearing the scene to avoid detonating an explosive device
- Contact the manager or person in charge of the building
- Building search should be conducted by personnel familiar with the premises, with police assistance if necessary
- Evacuation procedures:
- Evacuate everyone if an explosive device or suspected device is found
- Be aware of the possibility of a second device
- Post guards at entrances
- Evacuation distances depend on the size of the explosive device:
- Small device (up to 5 lbs.): up to the size of a shoe box or lunch box
- Medium device (up to 10 lbs.): small attaché case/large handbag
- Large device (up to 50 lbs.): large suitcase
- Unknown sized device: secure perimeter of 300 feet
Bombing Scene Procedures
- Establish a perimeter by locating the furthest piece of debris from the blast seat
- Limit admittance to the scene to authorized personnel
- Use one entry/exit path to minimize the chance of destroying fragile evidence
- Be cautious of secondary devices while securing the perimeter
Elementary Chemistry of Fire
- Four elements of fire: heat, oxygen, fuel, and uninhibited chain reaction
- Heat is transferred in three ways: conduction, convection, and radiation
- Phases of structural fires:
- First Phase (incipient): fire produces gases, rapid progress after flaming starts
- Second Phase (free burning/flame producing): major involvement, convection heating
- Third Phase (Smoldering): burning is reduced to glowing embers, toxic/flammable gases present
