Exemplar

A known or the source from which evidence originated.

Exemplar is useful

to match evidence at crime scene with source from suspect possession.

Primary crime scene

origin of crime

Secondary crime scene

additional place where evidence for crime can be found.

role of first police officer

secure crime scene, establish a perimeter, separate suspects and victims and witnesses.

Henry Faulds

Who developed the first classification system for fingerprints?

AFIS

Name of the current electronic fingerprint system

Patent prints

Prints that are visible, in blood, paint, oil, ect

Latent prints

Prints that are hidden to the eye

Plastic prints

indents of prints left in soft material

Iodine

react with carbohydrates in our fingerprints and produces brown prints. works best on paper and cardboard.

cyanoacrylate

fuming with super glue and produces white prints

silver nitrate

reacts with the sodium in salts secreted onto fingerprints through sweat glands, produces red prints (works best on styrofoam and wood)

ninhydrin

reacts with the amino acids in fingerprints and produces purple prints (works best on paper)

HemaStix

a blood reagents test with ___ coated in tetramethylbenzidine that turns green in the presence of hemoglobin

Leuco Crystal Violet

a test that make blood easier to view in photographs

Luminol

a test used when blood is very difficult to find (if it was cleaned up). it interacts with the iron in blood and a positive result turns blue

phenolphthalein

a blood reagents test that reacts to hemoglobin and turns pink if the protein in present (also called Kastle-Meyer Test)

fluorescein

a test used to detect latent or old blood. if positive, turns green (only visible under UV light)

UV light

powerful light source that can be used to detect a variety of fluids including blood

lines of convergence used to determine

what is used to determine the source or origin on blood spatter

types of evidence

testimonial, physical, trace

types of fingerprints

loop, whirl, arch

types of blood spatter

passive, projected, transfer

what are the things you can tell from blood spatter

angle of impact, velocity, direction of movement, and the lines of convergence (and origin and height)

swipe
