2,4,6‐Tri(2′‐pyridyl)‐1,3,5‐triazine for determination of iron(II), Iron(III), and total...

When iron‐based tools, such as knives or guns, are held, traces of iron can transfer to the skin. However, no previous studies have been published regarding the effect of the elapsed contact time on the transfer of iron species with different valences to the palm. Compared with 3...

Environmental assessment of gunshot residue particles in the public domain of the United...

Only limited data currently exists on the inadvertent transfer of gunshot residue (GSR), or GSR‐like particles through contact with public places. In this study, an assessment occurrence of GSR in public environments in England, UK was undertaken. Utilizing a stubbing sampling te...

Can latent fingerprint disclose the sex of the donor? A preliminary test study using GC–MS...

While fingerprints are a highly used means of identification, not every fingerprint left behind on a potential crime scene can be used for identification purposes. In some cases, the fingerprint may be smudged, partially preserved or overlapping with other prints hence distorting...

Shedder status—An analysis over time and assessment of various contributing factors

The shedder status of a person is an important consideration when evaluating probabilities of DNA transfer during activity‐level assessments. As an extension of our previously published study, the shedder statuses of 38 individuals were reassessed 1 year later. The study found th...
