AAFS – American Academy of Forensic Science
Abandonment: Knowingly giving up one’s right to property without further intending to reclaim or gain possession. Abandoned property can be searched by police officers without a search warrant. Most states deem it illegal to abandon motor vehicles, and the owner may be summoned to civil court to answer charges, pay fines, or to receive notice of vehicle impoundment and disposal.
Abduction: The criminal act of taking someone away by force, depriving that person of liberty or freedom. A person who has been kidnapped against their will has been abducted. This definition does not apply to a law-enforcement officer in the performance of his duties.
*FYI writers – Local police agencies can and do investigate kidnapping/abduction cases. I’ve worked and solved several. The FBI does NOT have to be called for abduction cases.
Abscond: To covertly leave the jurisdiction of the court or hide to avoid prosecution or arrest. A suspect who “jumps bail” or hides from police, while knowing a warrant has been issued for her arrest, has absconded from justice. Film director/producer Roman Polanski absconded to France before he could be sentenced for having unlawful sex with a minor.
Adipocere – Waxy substance found on decomposing bodies (consisting of fatty tissue). Also known as grave wax.
Affidavit – Written statement of facts given under oath.
ALS (Alternate Light Source): Lighting equipment used to enhance/visualize potential evidence.
APIS – Automated Palmprint Identification System.
Armed Robbery: Robbery is the act of taking, or seizing, someone’s property by using force, fear, or intimidation. Using a weapon, such as a gun, knife, or club, to carry out the same robbery constitutes an armed robbery. You have NOT been robbed when someone breaks into your home while you’re away and steals your TV.
Badge Bunny: Nickname given by police officers to females who prefer to date only police officers and firemen. Many of these badge bunnies actively pursue recent police academy graduates to the point of actually stalking the officers. Some have even committed minor offenses and made false police complaints to be near the officers they desire. Many police academies mention badge bunnies near the end of the officer’s academy training to prepare them for the possible situation.
BDU – Battle dress uniform (often worn by crime scene investigators, SWAT, canine officers, and entry teams).
BioFoam – A substance used to make impressions.
Bond – Money or other security posted with the court to guarantee an appearance.
Case File: Collection of documents pertaining to a specific investigation. The case file specific to a particular homicide investigation is sometimes called the “murder book.”
Case Identifiers: Specific numbers or alphabetic characters assigned to a specific case for the purpose of identification. For example – Case #ABC-123 or #987ZYX
Chalk Outline – This is a myth. Police DO NOT outline the bodies of murder victims. Why not? Because doing so would contaminate the scene. Tracing around the body could also move vital evidence. Crime scenes are photographed, not color-in with fingerprints or pastels.
Chase: Empty space inside a wall, floor, or ceiling that’s used for plumbing, electrical, and/or HVAC ductwork. A chase is a common hiding spot for illegal contraband and/or evidence (murder weapons, narcotics, stolen items, etc.).

Complaint – Statement given under oath where someone accuses another person of a crime. Officers may also refer to a call as a complaint. “Man, I caught two loud music complaints in one hour last night.”

Cook – Make crack cocaine or methamphetamine.

EDTA – Anticoagulating agent (tubes containing EDTA have purple tops).
Electrostatic Dust Lifter: Device that electrically charges a piece of plastic film that’s placed over a print made in dust (a shoe or palm print, for example), which in turn causes the dust to adhere to the film. The result is a perfectly captured print that’s ready for photographing.
Fire triangle – Three must-haves for a fire to burn—heat, fuel, and oxygen.
