EVIDENCE OF ARSON OBJECTIVES Identify types of evidence

EVIDENCE OF ARSON

OBJECTIVES • Identify types of evidence • Demonstrate collection, documentation, and packaging of evidence • Understanding evidence analysis

TYPES OF EVIDENCE TO COLLECT • Physical – Tool Marks – Fire Debris – Hydrocarbons – DNA – Prints • Statements (witness, suspect, victim) • K-9 Alerts • Video/photo • Cell phone

EXAMPLES OF PHYSCIAL EVIDENCE • • Tool marks Fire debris (accelerants) Liquid sample (accelerants) DNA Fingerprints Powder analysis Fracture patterns

TOOL MARKS

FIRE DEBRIS IGNITABLE LIQUID PRESENSE

Hydrocarbon Evidence In Soil • Hydrocarbon evidence in soil must be placed in a clean, metal can • The can with the evidence must be kept frozen until it is analyzed by forensic technicians • Bacteria in the soil will degrade the hydrocarbon • Placing the evidence in a freezer will slow down the process of degradation

LIQUID SAMPLE IGNITABLE LIQUIDS

Pipette/Glass vial

Liquid Evidence packaged

DNA EVIDENCE

Dry DNA Evidence/Fingerprints

PRINTS

POWDER ANALYSIS

• Or anti-static collection bag

FRACTURE PATTERNS

OTHER EXAMPLES

INCENDIARY DELAY DEVICE

STATEMENTS Documentation of events, crime scene observations, statements (witness, victim, suspect), and anything pertinent to the investigation. **Remember, you may be testifying to these observations a significant time after the incident.
