FSC239Y5 Lecture Notes - Dot 4, Cyanoacrylate, Silver Nitrate
Document Summary
Collection: photography, fingerprint tape, dental stone lift, sulfur casts, electrostatic lifters, gel lifters. An intentional or unavoidable characteristic that repeats during the manufacturing. Tread pattern, type of footwear, size, wear pattern, defects. Physical shapes, spatial relations with each other . Fingerprint id three conclusions, will match the person. Footwear and tire tracks more variables that will change the impression. There is a spectrum for the types of conclusions. Blood reagents, bb, potassium thiocyanate, iodine fuming. Photography: designation number, date, location, initials, badge. Fingerprint tape on acetate or backing card. Photography: scale in the same plane, lens perpendicular, designation number. Fingerprints: recognize and identify: training, document: photography (perpendicular to surface of evidence), notes and sketches, collect: intact and submitted to lab, conclusion. Residue deposited by friction ridges of the human hand. If the damage exceeds the dermal papillae (includes a code which will regenerate in the same pattern), there would be no regrowth of fingerprints.
