PRESENTATION OUTLINE

FIBERS

LUIS ARREDONDO

FIBERS CANNOT DEFINITIVELY PINPOINT TO A CULPRIT BECAUSE THEY CARRY NO DNA

FIBERS ARE COLLECTED BY USING TWEEZERS, TAPE, OR A VACUUM

FIBERS ARE FIRST DETERMINED WHETHER THEY ARE NATURAL, MANUFACTURED, OR BOTH

A MICROSPECTROPHOTOMETER IS THE MOST EFFECTIVE WAY TO ANALYSE FIBERS

THE FIRST STEP IN ANALYSIS IS TO COMPARE COLOR AND DIAMETER

THE WAYNE WILLIAMS CASE IS THE FIRST CASE TO HAVE RELIED ON FIBER ANALYSIS FOR THE EVIDENCE

THE SPECTROMETER SEPARATES LIGHT INTO COMPONENT WAVELENGHTS

THE COMPARISON MICROSCOPE IS USED FOR MORE PRECISE IDENTIFICATION

NATURAL FIBERS COME FROM PLANTS OR ANIMALS

MANUFACTURED FIBERS ARE MADE FROM LONG STRANDS OF POLYMERS
