Examination of bomb scene evidence is an area of increasing involvement for the forensic scientist in which incidents may vary from student mischief to mass murder. To undertake explosive casework responsibilities, the scientist must have personal experience of the type of physical evidence left after explosions, including device remains, characteristic damage, and chemical residues.
Numerous forensic science laboratories have approached the identification and comparison of automotive paints differently, but the paint samples are normally subjected to a series of microscopic and chemical examinations that yield chromatic and geometric appearance information as well as fundamental molecular information concerning the types of resins and pigments present.
A rapid system for the identification of Chrysler Corp. vehicles from paint samples has been devised. The data presented outline the production relationships of Chrysler vehicle lines to their various assembly plants from 1960 to 1979. Marketing trends seen in our data illustrate the usefulness of a statistical data base. Microscopic and chemical data from the analysis of 107 core samples, representing paint samples collected from 1452 Chrysler Corp. vehicles, are presented and discussed.
The recent advancement of highly specialized instrumentation and instrumental techniques has enabled the forensic scientist to analyze paint samples in the microgram and picogram ranges. The limiting factor is often the physical recovery of small samples for microchemical analysis. A number of chemical procedures have been employed for the microanalysis of paints. Both infrared spectrophotometry (IR) and pyrolysis-gas chromatography (PGC) are popular techniques for the identification and comparison of paints.
