Forensics Fingerprints Test
___ powder also can be used to expose latent prints - ANS-Magnetic; this type of powder
works better on brilliant surfaces or plastic baggies and containers
A fingerprint is manufactured from a sequence of ___ and ___ - ANS-ridges and valleys, on
the floor of the finger
Accidental Whorl - ANS-A mix of various patterns. It cannot be labeled as any other sample.
According to crook investigators, fingerprints follow 3 essential principles: - ANS-1)
fingerprints are *man or woman traits*, no people had been discovered with the EXACT
equal fingerprint
2) a fingerprint sample *will stay unchanged for the life of an individual*, however may
additionally distort due to everlasting scars and pores and skin illnesses
3) fingerprints have *general ridge traits* that permit them to be systematically identified
(ridges are inside the fingerprint)
AFIS - ANS-Automated Fingerprint Identification System. Scans fingerprints electronically
and plots the positions in their ridge traits, comparing them with prints in a database.
Central Pocket Whorl - ANS-Two deltas, a line drawn among the deltas doesn't go through
the central pocket
Classes of Fingerprints: Arch - ANS-Plain Arch (shown)
Tented Arch (peaks, seems like sharp mountain)
Classes of Fingerprints: Loop - ANS-Radial Loop, Ulnar Loop
Classes of Fingerprints: Whorl - ANS-Plain whorl, significant pocket whorl, double loop
whorl, unintentional whorl
Cyanoacrylate fuming - ANS-superglue approach
Super glue reacts with the strains of amino acids, fatty acids, and proteins inside the latent
fingerprint and the moisture within the air to provide a visible, sticky white fabric that
bureaucracy along the ridges of the fingerprint. The very last end result is an image of the
complete latent fingerprint. This picture may be photographed immediately, or after further
enhancement. However, the glue must be in gaseous nation. To try this, one places the
surface suspected of containing a latent fingerprint in a container with a heater in it. Then,
they area a small, opened box of the glue on top of the heater, and punctiliously seal the
overall one. After that, definitely wait.
