Associative Evidence - any evidence that places an individual at a scene and/or with a victim
Class Evidence - evidence that requires classification into a more narrow range
Electronic Evidence - information and data transmitted and/or stored in any electronic device
Latent Evidence - any evidence that is not visible without the use of chemical, photographic, or
electronic development / enhancement
Trace Evidence - evidence that has to be extracted from another substance and is in very small amounts,
often invisible to the naked eye
Indicative Evidence - evidence that substantiates or proves that a certain period of time has elapsed
Circumstantial - facts, observations, activities from which the culpability of an individual may be inferred
LOSER - LISTEN to victims and/ or witnesses
OBSERVE the scene and surroundings- including the approach
SEARCH for potential victims, suspects, witnesses, and physical evidence
EVALUATE the scene and information obtained - does it add up?
RECORD information in a memorandum or case book
Role of the First Responder - -three tiered response: police, fire department, emergency medical services
-all scenes must be treated as criminal investigations as any incidence can have criminal origin
-first officer at the scene identifies and initiates the appropriate respond
