A serial killer of elderly women: Analysis of a multi-victim homicide investigation

A case of serial killing by poisoning by a 59-year-old practical nurse is discussed. Following a report by an emergency-room doctor of an attempted murder, police performed an investigation into all deaths of patients in the nurse's care. Earlier, a medico-legal cause-of-death investigation had been performed on two of these cadavers, but in the other three cases the death certificate had been issued after a medical investigation only. In two of these latter cases, the body had been cremated, but fixed histological samples taken at medical autopsy were available, while in one case the person had died recently and the body was thereafter exhumed and autopsied. All of the suspected victims were older people who required nursing, and the nurse's course of action was consistent in all cases. In the absence of ordinary post-mortem toxicology samples in the medical cases, extraordinary evidence--paraffin-embedded liver tissue samples originally taken for histology at autopsy--was successfully recovered in two cases and analyzed for drugs. In all five cases, drugs not prescribed to the patient were detected, including digoxin, dixyrazine, citalopram, venlafaxine, and benzodiazepines (diazepam, chlordiazepoxide, temazepam, and oxazepam). The nurse was eventually found guilty of five murders by poisoning, five attempted murders, and three aggravated assaults. The nurse was sentenced to life imprisonment.

Excepting psychiatry, psychology and medicine remain largely separate disciplines. In forensic inquiries, the psychologist assesses the mind, whereas the pathologist examines the body. Both fields, however, actively participate in the same investigations, albeit from different standpoints, contributing to explorations of crime scene dynamics, identification of offenders, and legal proceedings.In recent years, peer review has become a staple of research, because subjecting work to scrutiny by other experts promotes accuracy.

Elderly abuse is still a hidden problem, often underestimated. It is much more common than the data available suggest. Unfortunately, the incidence is expected to grow with the progressive increase in the elderly population in the future. The aim was to examine the available literature in the last 5 years to define the state of art on this phenomenon, with particular regard to the nursing role in elderly abuse, focusing on the possible types of mistreatment, the motivations and preventive interventions. Articles published in the last 5 years regarding the mistreatment of the elderly were selected, by using scientifically recognized databases such as PubMed, Cochrane Library, Medline, Scopus, and Web of Knowledge. Several keywords were used for the query among which were: "elderly abuse" and "elderly abuse in nursing home". Moreover, to better understand the entity of the phenomenon, we also searched the corresponding keywords for child abuse. Considering the Scopus database, only 78 out of 1,342 published articles in the last 5 years deal with abuse of the elderly in relation to nursing, representing a very small part (5.81%) of the considered sample. Comparing the number of articles, the ratio child/elderly is equal to 1/0.04, underlying the poor interest of research on this phenomenon. Moreover, it was observed that elderly abuse in nursing homes is still underreported in both original articles and reviews. Despite the aging of the population, elderly abuse and neglect still remain hidden problems, overlooked and also underestimated in the literature.
