Radiocarbon dating as tool to assist in triaging cases of unidentified human remains in Victoria,Australia: A case series

In cases where human remains are unidentified because there is no initial identification hypothesis, limited contextual information, and/or poor preservation, radiocarbon (¹⁴C) dating may be a useful tool to further assist with identification. Through measuring the amount of ¹⁴C remaining in organic material, such as bone, teeth, nail, or hair, radiocarbon dating may provide an estimated year of birth and year of death for a deceased person. This information, may assist in, establishing whether a case of unidentified human remains (UHR) is actually of medicolegal significance and therefore, requires forensic investigation and identification. This case series highlights the application of ¹⁴C dating to seven of the 132 UHR cases in Victoria, Australia. Cortical bone was sampled from each case and the level of ¹⁴C was measured to provide an estimated year of death. Four of the seven cases analyzed contained the levels of ¹⁴C consistent with an archeological timeframe, one contained a level of ¹⁴C consistent with a modern (i.e., of medicolegal significance) timeframe, and the results for the remaining two samples were inconclusive. Applying this technique not only reduced the number of UHR cases in Victoria but also has investigative, cultural, and practical implications for medicolegal casework in general.     

Older adults in secure mental health care: health,social wellbeing and security needs measured with HoNOS-secure across different age groups

The number of older offenders is rapidly increasing in the United Kingdom and some older adults with mental health issues are referred to secure care services. It is therefore important to understand their unique characteristics in order to develop services based on their individual needs rather than chronological age. This study explored wellbeing and security needs of younger and older patients admitted to a secure psychiatric hospital. HoNOS-secure assessment at admission and discharge was extracted and used to build an anonymous data-set. Group comparison and score change during admission were conducted for six age groups: 18–24, 25–34, 35–44, 45–54, 55–64 and 65+. Younger patients improved on most measures whereas older patients aged 55–65+ showed little improvement or deterioration over time. This finding suggests that the subscales are sensitive to age difference although the needs measured by HoNOS-secure are less likely to inform the decision to discharge.
