Can Neck Contusions in Unexplained Pediatric Deaths be Explained by Cardiopulmonary Resuscitation?

The distribution of cutaneous contusions in infants may raise the possibility of maltreatment. Neck contusions are particularly problematic since they seldom occur outside the setting of abuse, while cardiopulmonary resuscitation (CPR)‐related maneuvers may involve the neck. To address the role of CPR in neck findings, we examined 260 consecutive pediatric autopsies in which CPR was attempted. No neck contusions were identified in manners of death classified as natural, undetermined, or suicide. Contusions were present in two of 80 deaths classified as accident and had obvious accidental causes. About 26% of deaths classified as homicide had neck contusions with no explanation provided by the caregiver (p < 0.0001). In conclusion, neck contusions in deceased children with no apparent explanation should be regarded as suspicious for abuse and investigated accordingly. CPR is not a plausible explanation for neck contusions in children.     

A Forensic Entomological Analysis Can Yield an Estimate of Postmortem Interval,and Not Just a Minimum Postmortem Interval: An Explanation and Illustration Using a Case

Several authors claimed that a forensic entomological analysis can never be interpreted as the postmortem interval (PMI), but that it can be interpreted as a minimum postmortem interval (PMI_min), or dead for not less than X amount of time. Because in most instances, a PMI estimate should be a range, that is, the set of values from maximum postmortem interval (PMI_max) to PMI_min, objections to PMI estimation are objections to PMI_max estimation. The arguments for this position did not address the substantial body of literature describing estimation of both PMI_max and PMI_min using insect succession analysis. This report reviews the scientific issues and presents a recent homicide investigation in which several forensic entomology experts used the absence of carrion insects on the corpse, a kind of succession analysis, to estimate PMI or PMI_max.     

Deliberate ingestion of foreign bodies as a form of self-harm among inpatients within forensic mental health and intellectual disability services

Deliberate foreign body ingestion is a significant issue in prison and psychiatric settings. It is associated with serious physical complications, including bowel obstruction, perforation and haemorrhage. Episodes of deliberate foreign body ingestion were identified retrospectively from 5417 incident records from two inpatient forensic services (one mental health and one intellectual disability) over a one year timeframe, using related search terms. Rates were compared according to gender, diagnosis and level of security. Incidents of deliberate foreign body ingestion were found to occur on average every 2.7 days across the study population, with 133 incidents recorded over a one year period, accounted for by 27 patients. Women and patients in lower levels of security were significantly more likely to engage in deliberate foreign body ingestion. Staff responses to this behaviour were highly variable. Deliberate foreign body ingestion occurs frequently within inpatient forensic services, and can have significantly detrimental physical implications for affected patients. Further research should investigate the psychiatric and intellectual disability profile of such individuals in further detail, as well as exploring patient narratives; both of which will help inform development of treatment strategies.     

The Effects of Pre-admonition Suggestions on Eyewitnesses’ Choosing Rates and Retrospective Identification Judgments

Pre-admonition suggestion is an identification-relevant comment made to an eyewitness by a lineup administrator before the lineup admonition. Quinlivan et al. (2012) found that their suggestion inflated mistaken identification rates and retrospective identification. However, the suggestion used was a compound statement, making it unclear which component influenced choosing rates. The current experiment was conducted to parse out the effects. Participants (N = 211) viewed a crime video and received either one component of the compound suggestion (a suggestion to pick or that the witness had paid substantial attention), both components, or no suggestion. All participants received an admonition, made an identification choice, and answered questions about their witnessing experience. The results demonstrated that the pick suggestion increased mistaken identifications from a perpetrator-absent lineup whereas the effects of the attention suggestion were restricted to the retrospective judgments. These results show support for the role of secondary (non-memorial) processes in eyewitness identification.     

On the Diagnosticity of Multiple-Witness Identifications

It is not uncommon for there to be multiple eyewitnesses to a crime, each of whom is later shown a lineup. How is the probative value, or diagnosticity, of such multiple-witness identifications to be evaluated? Previous treatments have focused on the diagnosticity of a single eyewitness’s response to a lineup (Wells and Lindsay, Psychol. Bull. 3 (1980) 776); however, the results of eyewitness identification experiments indicate that the responses of multiple independent witnesses may often be inconsistent. The present paper calculates response diagnosticity for multiple witnesses and shows how diagnostic probabilities change across various combinations of consistent and inconsistent witness responses. Multiple-witness diagnosticity is examined across variation in the conditions of observation, lineup composition, and lineup presentation. In general, the diagnostic probabilities of guilt were shown to increase with the addition of suspect identifications and decrease with the addition of nonidentifications. Foil identification results were more complicated-diagnostic of innocence in many cases, but nondiagnostic or diagnostic of innocence in biased lineups. These analyses illustrate the importance of securing clear records of all witness responses, rather than myopically focusing on the witness who identified the suspect while ignoring those witnesses who did not.     

The validity of criminal justice contacts reported by inmates: A comparison of self-reported data with official prison records

Purpose

Existing research on criminal justice contact data has not adequately examined the quality of self-reported timing data, has produced discrepant findings on validity as it relates to demographics, and is limited in its assessment of data quality using a life event calendar method. The study described in this article assessed the validity of self-reported contacts with the criminal justice system gathered using a life event calendar with a sample of incarcerated men.

Methods

Self-reports of criminal justice contacts (i.e., arrests, jail terms, prison terms) were obtained from over 700 incarcerated men using a structured life-event calendar method. Similarly, data were collected from the inmate's official records for the same events. These reports served as an external criterion for the self-reports.

Results

Results indicated a significant degree of reporting errors for arrests using the life event calendar approach with better reporting for jail and prison terms. Additionally, individuals with the highest number of previous arrests had the greatest recall difficulties.

Conclusions

Recall of arrest presents a difficult recall task. The life event calendar method should either be modified to improve recall of specific events for criminological samples or used instead to capture information on more general and extended events.
