Regulatory trends in forensic science point strongly to the need for exhaustive testing of all findings and tools. At the same time a number ofjurisdictions suggest ajudicial test for the admissibility of novel scientific evidence. But in fields such as computers and cellphones, the rate of change is faster than the normal times required for peer-reviewed publication. One route to admitting les...

An amendment in 2002 to the Spanish Code of Criminal Procedure converted into documentary evidence the expert reports prepared by official laboratories aimed at determining the nature, weight, and purity of seized drugs. In most cases, experts are spared from appearance before the courts. This is likely to be extended to other forensic fields. After an overview of criminalistic identification i...

Review was undertaken from February 1969 to January 1998 at the State forensic science center (Forensic Science) in Adelaide, South Australia, of all cases of murder-suicide involving children <16 years of age. A total of 13 separate cases were identified involving 30 victims, all of whom were related to the perpetrators. There were 7 male and 6 female perpetrators (age range, 23-41 years; aver...

Nowadays, technological advances are becoming more and more important in forensic sciences. Yet autopsy is still one of the very traditional methods. This also applies for dentalautopsies, in which visual, photographic and radiological evidences are collected. In this context, Virtual Autopsy appears as a helpful and complementary tool for dental and medical cadaveric examination. Usinghigh-tec...

The debate in forensic science concentrates on issues such as standardisation, accreditation and de-contextualisation, in a legal and economical context, in order to ensure the scientific objectivity and efficiency that must guide the process of collecting, analysing, interpreting and reporting forensic evidence. At the same time, it is recognised that forensic case data is still poorly integra...

DNA fingerprinting is a powerful technology that has revolutionized forensic science. No two individuals can have an identical DNA pattern except identical twins. Such DNA-based technologies have enormous social implications and can help in the fight against crime. This technology has experienced many changes over time with many advancements occurring. DNA testing is a matter of serious concern...

Since the nineteenth century, food toxicology has evolved in several ways. The analytical power of the food toxicologist has been increased. The concept of adulterated food was modified significantly. Most commodities are now processed and addition of numerous non-nutrient additives is legalised. Other "alien" compounds get introduced in the food chain from background contamination or during pr...

This research examined how variations in the presentation of forensic science information affect factfinders' judgments in a trial. Participants read a summary of a murder case, the critical testimony being the results of a microscopic hair comparison given by a forensic expert. Across two experiments we manipulated how the expert expressed his results, whether he gave an explicit conclusion co...

Image fusion is a process of combining two or more images into an image. It can extract features from source images, and provide more information than one image can. Multi-resolution analysis plays an important role in image processing, it provides a technique to decompose an image and extract information from coarse to fine scales. In some practical forensic examinations (such as the cartridge...
