...AC Pounds, M. Phil.; R Grigg, Ph.D.; T Mongkolaussavaratana, Ph.D. The use of a new amino acid reagent 1,8-diazafluoren-9-one (DFO), which produces a highly fluorescent species with latent fingerprints on paper, is described. Spectral characteristics of the fluorescent fingerprint show excitation...

...DS Moore, B.S., M.Ed. For almost a decade, document examiners have used the electrostatic detection apparatus (ESDA) to detect and visualize indentations on paper. Many of the same papers that undergo the ESDA process, however, may also be capable of yielding latent print evidence of vital...

...FJ Gerhart, M.S.; DC Ward, B.S. Comparisons of torn paper matches are difficult, time-consuming microscopic examinations. A technique is described where adjacent match bodies are submerged in an ethanol/water solution resulting in a significant increase in the number of observable points...

...KC Dixon, M.S.F.S. Torn paper match examinations are one of the important types of examinations made by the Document Section of the FBI Laboratory and are probably some of the least heard about and least publicized examinations made by this laboratory. These examinations have often been extremely...

...II Ziderman, B.Sc., M.Sc., Ph.D. Evidence in the form of paper documents can be highly valuable in crimes of fraud. Available methods of examination do not provide absolute certainty that two samples have the same origin. A new technique for testing paper, known as inverse paper chromatography...

...AH Lyter, III, M.S. A relatively simple examination of suspect water-soluble paper residue can be performed by using chemical testing and microscopic and instrumental procedures, and meaningful results can be obtained. The consistency between test results of individual constituents and actual...

...JD Kelly, M.S.; P Haville, B.S. A method is presented for the characterization of zinc oxide photocopy papers. The tests include nondestructive physical examinations of weight, pH, and color under ultraviolet light. Chemical tests, consisting of thin-layer chromatographic examination...
