Response Assessment of Thermal Papers from Four Continents to Fingerprint Development by Heat

Latent fingerprint deposits on thermal paper sourced from the U.S., China, the U.K., and Australia have been visualized by heating. U.S. and Chinese sourced paper produced two distinct types of fingerprint development. In one type (type 1), the paper dye colors where the deposit is present (as previously reported) and in the other type (type 2) the ‘inverse’ of this gives paper coloring only in areas not coincident with the deposit. Both development types gave identifiable fingerprints, the majority fading within 24 h of heating. Fingerprint development from U.K. and Australian sourced paper was exclusively type 1 and resistant to fading. Temperatures for fingerprint visualization were higher for U.S. paper (64–71°C) and Chinese paper (75–95°C) than for U.K. and Australian sourced paper (43–50°C). Particularly for Chinese sourced paper, these temperatures were within a few degrees of the normal paper color temperature. A mechanism for type 2 fingerprint development is proposed.

电热板消解电感耦合等离子体质谱法测定人发中33种无机元素的含量

目的建立头发中33种无机元素的电热板消解电感耦合等离子体质谱（inductivelycoupledplas—ma—IllasssDectrometry,ICP—MS）测定方法。方法以锂（6Li）、锗（^72Ge）、钇（^89Y）、铟（^115In）、铽（^159yb）作内标,硝酸和过氧化氢作为消解酸体系．采用电热板消解对头发进行前处理,ICP—MS法分析人发中33种无机元素的含量。结果电热板消解ICP—MS法的检出限为0．0001μg／g（Th）-10．9μg／g（Ca）,定量限为O．0005μg／g（Th）～25μg／g（Ca）,加标回收率为86％～113％,日内及日间精密度≤9.2％,与微波消解法检测结果相比,差异无统计学意义。结论电热板消解ICP—MS法高效、准确度高,适用于对头发中33种无机元素的分析。     

An Unusual Pattern of Decomposition Associated with Suicidal Electrocution in a Bath

A 51‐year‐old man was found dead face down and partially submerged in a bathtub alongside two hairdryers. The hairdryers had continued to work, as the victim had bypassed the electrical board of the house prior to dropping them into the water. This had resulted in death due to electrocution, with subsequent heating of the bath water causing marked putrefaction and softening of the immersed body parts. The back and feet, which were not submerged, were preserved. The degree of anterior decomposition was not in keeping with the postmortem interval; however, regional decomposition with sparing of the back and feet provided a clue at autopsy as to the sequence of events. Individuals with training in, or knowledge of, electrical circuitry are capable of modifying domestic wiring so that safety switches and/or fuses can be bypassed ensuring that electrical devices will continue to function even while under water.
