Filicide, attempted filicide, and psychotic disorders

The objective of the study was to describe and discuss the cases of two women who faced criminal charges, one for attempting to murder her three children and the other for killing her 1-year-old boy. After a forensic psychiatric assessment of their level of criminal responsibility, these patients were considered not guilty by reason of insanity and were committed to forensic mental hospitals. These two patients received a diagnosis of paranoid schizophrenia, according to the DSM-IV-TR criteria. In both cases, psychotic symptoms were present before the manifestation of violent behavior, in the form of persecutory delusions, auditory hallucinations, and pathological impulsivity. The investigation into cases of filicide may contribute powerfully to expand our understanding of motivational factors underlying this phenomenon and enhance the odds for effective prevention.     

Double parricide: forensic analysis and psycholegal implications

In a retrospective study, eleven adult parricidal forensic cases from Southern California are presented. Each case involves the murder of both parents and was referred for forensic evaluation. Common characteristics among the eleven cases are presented. Two case examples illustrate features of recognized adult parricidal subtypes. The findings are compared with studies involving parricide, double-parricide, and extant case law.     

Psychiatric morbidity in murder and attempted murder crime convicts: a Turkey study

In the present, the morbidity of psychiatric disorders of homicide/attempted homicide crime convicts imprisoned in Turkey, Sivas maximum security prison was investigated. Seventy imprisoned homicide/attempted homicide crime convicts included in this study. Sociodemographic information form, structured clinical interview for DSM-IV Axis-I disorders and structured clinical interview for DSM-III-R personality disorders applied to the participants. Most commonly diagnosed disorders among those convicts were current Axis-I disorders, depressive disorders (7.1%) and anxiety disorders (5.7%). Among Axis-I disorders, the most diagnosed one was the substance use disorders (45.7%). The most diagnosed Axis-II disorder was found as to be antisocial personality disorder (48.6%). The rate of convicts who were diagnosed as having both Axis-I and Axis-II disorders was 51.4%. The most prevalently accompanying lifetime Axis-I disorders to antisocial personality disorder with respect to Axis-I, and Axis-II comorbidity was substance use disorders. As a result, it was thought that the substance use disorders and antisocial personality disorder among the homicide/attempted homicide crime convicts were the most prevalent lifetime psychiatric disorders.     

Psychopathology and weapon choice: a study of 103 perpetrators of homicide or attempted homicide

Bone marrow (BM) analysis is of forensic interest in postmortem toxicological investigation in case of limited, unavailable or unusable blood samples. However, it remains difficult to determine whether a drug BM concentration is therapeutic or represents overdose, due to the lack of studies on this alternative matrix. Given the variations in BM composition in the body, sample location was suggested to be a relevant factor in assessing BM concentration. The aim of the present study was to compare postmortem caffeine concentrations in various BM sample locations and secondly to consider the correlation between BM and blood concentrations. Six BM samples (right and left side: proximal and medial femur and 5th rib) and a blood sample were collected from 21 forensic autopsies. Gas chromatography coupled to tandem mass spectrometry was performed. Blood caffeine concentrations ranged from 60 to 7591ng/mL. Femoral and rib BM concentrations ranged from 51 to 6171ng/g and 66 to 7280ng/g, respectively. Blood concentrations were always higher than BM concentrations. As a good correlation was demonstrated between blood and rib BM and between blood and the average of the four femoral BM concentrations, blood caffeine concentrations could be correctly extrapolated from BM concentrations. BM caffeine concentration was found to depend on sample location. Rib BM caffeine concentrations appeared to be systematically greater than averaged femur values and concentrations were much more variable between the 4 femur BM samples than between the 2 ribs. From a practical point of view, for caffeine analysis, rib BM appeared more relevant than femoral BM, which requires multisampling to overcome the concentration variability problem.     

Own-age bias in video lineups: a comparison between children and adults

Abstract

The present study investigated whether child (six–eight years of age) and adult witnesses (18–29 years of age) would exhibit an own-age bias when trying to identify targets from video lineups. One hundred and eighty-six participants viewed two filmed events that were identical, except one starred a child target and one a young adult. After a delay of two–three days each witness saw a lineup for the child and adult target. Children exhibited an own-age bias and were better at correctly identifying the own-age target from a target-present (TP) lineup and made more correct rejections for the own-age target-absent (TA) lineup. Adults however, showed a reversed own-age bias for the TP lineups as they made more correct identifications for the child target, but exhibited no bias for the TA lineups. The results suggest that differences in identification accuracy may be due to whether witness age and suspect age overlap.

A comparison of the abuse experiences of male and female adults molested as children

Do the molestation experiences of boys and girls differ? The present study analyzed data from 365 adults molested as children, and compared findings for males and females on the identity of the perpetrator, age at onset and end of molestation, duration of molestation, type of sexual acts, and whether the molestation was reported to law enforcement. Results indicated that boys and girls were equally likely to be molested by natural fathers, girls were more likely to be molested by stepfathers, and boys were more likely to be molested by friends of the family. Molestation started at the same age for boys and girls, but lasted longer and ended at a later age for girls. Males and females were equally likely to experience fondling from the waist down and oral intercourse. However, there were significant differences for incidence of anal intercourse and fondling from the waist up. Findings are discussed in the context of previous research in the field.     

Dental age estimation of Norwegian adults — A comparison of different methods

Age estimations were performed on 100 teeth according to the methods of Bang and Ramm (unsectioned and sectioned teeth), Miles, Johanson, and Dalitz, and in addition by visual examination of the unsectioned teeth. Mean error as well as standard and mean deviations were calculated. The method of Johanson was found to be slightly more reliable than the others. Visual estimation was also in some respects better than the other three methods. All methods resulted in the largest number of overestimates in teeth from persons below 40 years, from males, from the maxilla, and in teeth removed from corpses. Underestimates were predominant in teeth from persons above 50 years.     

A comparison study of hair examination methodologies

A study was conducted to investigate the accuracy between two methods of hair analysis: PCR-STR DNA analysis and microscopic comparison analysis. Standard sets of pubic hairs were collected from volunteers, and unknown sets were generated from these samples. Three out of five (60%) of the hairs analyzed produced full DNA profiles that were correctly matched to the standard sets. DNA analysis was inconclusive (partial or no DNA profile) for two out of five (40%) of the samples. In contrast, the microscopic comparison analysis correctly matched four out of five (80%) of the samples to the standard sets but mis-identified one out of five (20%) of the samples. These results reinforce the practice of preliminary microscopic hair examination in narrowing down a set of hairs for DNA analysis. Microscopic comparison analysis is sufficiently reliable to remain a rapid and inexpensive method for forensic hair analysis.     

Outpatient commitment and coercion in New Zealand: a matched comparison study

BACKGROUND: It has been hypothesized that a degree of coercion is a necessary component in using outpatient commitment to attain therapeutic outcome for those people subject to mental health law. However, what degree of coercion is required and how it is sustained is poorly understood. There is speculation that patients' recognition of beneficial as well as unwanted aspects of outpatient commitment (ambivalence) maybe an indicator that the necessary level of coercion has been achieved to facilitate a therapeutic outcome. AIM: The aim of this study was to determine the level of coercion perceived by those under outpatient commitment in New Zealand. Emphasis was given to consideration of the presence of ambivalence and the role of interactive processes, including procedural justice, in influencing patients' perceptions of coercion. METHOD: A cross-sectional comparative study was undertaken to compare the perceptions of coercion of patients on outpatient commitment (n = 69) to a matched sample of voluntary outpatients (n = 69), using the Perceived Coercion Scale. The influence of a range of variables, including patients' knowledge of and beliefs concerning outpatient commitment, were considered. RESULTS: Although the level of coercion for involuntary outpatients was relatively low, it was significantly higher than that experienced by voluntary outpatients. Yet involuntary outpatients were more likely to espouse benefits of outpatient commitment. Although there was an inverse correlation between perceptions of procedural justice and perceived coercion, procedural justice did not feature in the linear regression analysis. DISCUSSION: In the New Zealand context, involuntary outpatients hold contrasting views to outpatient commitment. We suggest that this ambivalence is an indicator that the degree of coercion is suffice to achieve therapeutic outcome. Furthermore, this study suggests the impact of procedural justice on patients' perceptions of coercion may be more crucial during admission to hospital than in the context of on-going community care.     

Skeletal identification using the frontal sinus region: a retrospective study of 39 cases

The importance of identification using the frontal sinus has been previously demonstrated in case reports. In this study, 39 cases of identification using frontal sinus comparison from the Ontario Chief Coroner's Office were reviewed and differences between antemortem and postmortem radiographs examined. All cases involved decedents older than twenty years. Three cases were rejected due to poor antemortem and postmortem film quality. One subject had no frontal sinus. Thirty-five cases provided conclusive postmortem to antemortem pattern matches. Sixteen cases also yielded metric (quantitative) matches. Duration between antemortem and postmortem radiographic examinations, age, gender, and cause of death did not affect the ability to obtain a match. This is the largest study undertaken on actual cases and demonstrates the validity of frontal sinus pattern matching for forensic identification.     

Entrepreneurial universities in two European regions: a case study comparison

An entrepreneurial university is a natural incubator that tries to provide a supportive environment in which the university community can explore, evaluate and exploit ideas that could be transformed into social and economic entrepreneurial initiatives. Entrepreneurial universities are involved in partnerships, networks and other relationships to generate an umbrella for interaction, collaboration and co-operation. Rapid developments in science, the multidisciplinary nature of frontier research, legislative changes such as the Bayh–Dole Act and demands from business and society have shaped knowledge-based entrepreneurship within universities. Despite sharing similar historical backgrounds, economic conditions and cultural and social structures, entrepreneurial universities in most countries remain distinct from one another by their institutional arrangements, traditions and characteristics unique to each organization. Interestingly, no comparative research has been conducted to understand the similarities and differences of the conditioning factors and the outcomes/outputs of entrepreneurial universities in different regions that share similar social, economic and political conditions. This paper addresses this research deficit, adopting institutional economics and resource-based view. We compare entrepreneurial universities in two European regions (Spain and Ireland) using an in-depth qualitative approach based on multiple case studies (two Spanish universities and two Irish universities) between 2006 and 2010. The findings provide organizational practices and approaches relevant to the transformation process of other regional universities seeking to become entrepreneurial.     

Delayed left anterior and middle cerebral artery hemorrhagic infarctions after attempted strangulation: a case report

The 2 common carotid arteries bifurcate in the neck into the internal and external carotid arteries. The internal carotid artery enters the skull and further divides into the anterior and middle cerebral artery. During its short course in the neck, the carotid artery travels encased in the carotid sheath along with the vagus nerve and the internal jugular vein. During its course in the neck, the carotid artery is quite superficial, making it vulnerable to both penetrating and blunt traumatic injuries. We report here a case of a 40-year-old man who presented to the emergency department after sudden collapse and loss of consciousness a day after an attempted strangulation. Imaging revealed large hemorrhagic infarcts in the left anterior cerebral artery and middle cerebral artery territories as well as a smaller infarcts in the right anterior cerebral artery territory necessitating emergency decompressive hemicraniectomy. Our case report adds to the existing literature on nervous system injury due to strangulation. Physicians should be aware of the possibility of delayed presentation of neurological deficit after attempted strangulation.     

A decade of child-initiated family violence: comparative analysis of child--parent violence and parricide examining offender, victim, and event characteristics in a national sample of reported incidents, 1995-2005

This article examines 11 years (1995-2005) of National Incident Based Reporting System data comparing victim, offender, and incident characteristics for two types of child-initiated family violence: child-parent violence (CPV) and parricide. The objective is to better understand the victim-offender relationship for CPV and parricide and to highlight distinguishing features between the two offenses. This work extends the research and addresses shortcomings in the extant literature. Data analysis consists of chi-square tests and logistic regression. Findings suggest that CPV and parricide are distinct and unique crimes. In short, parricide offenders and victims are both older than CPV offenders and victims, with CPV offenders more likely to be female, more likely to be African American, and less likely to use a weapon than parricide offenders. The study calls for future research and exploration of preliminary support for a family violence escalation hypothesis.     

Trace evidence dynamics of cocaine on banknotes: A comparison study of paper and polymer banknotes

It is well established that a large proportion of paper banknotes in circulation contain traces of cocaine. Being able to discriminate between the innocent transfer of illicit drug particles acquired through everyday interactions with surfaces such as banknotes, as opposed to transfer resulting from criminal activities can provide valuable intelligence that can inform an investigation. With many countries adopting polymer banknotes as legal tender, it is important to consider the transfer of cocaine from these surfaces as well as the retention of these particulates on polymer banknotes for evaluative interpretation in crime reconstruction. This comparison study assessed three contact variables (force, time, and rotation) on the transfer of cocaine particulates from paper and polymer banknotes onto a human skin proxy. The persistence of cocaine particulates was assessed through a realistic scenario which mimicked a cash transaction. Quantifiable amounts of cocaine were transferred onto the human skin proxy across all of the contacts assessed, with a greater transfer observed with contacts involving polymer banknotes and those contacts which involved rotation. Following extensive handling, cocaine persisted on both banknote types, with paper banknotes retaining larger amounts of cocaine than polymer banknotes. These findings show that cocaine can persist on both paper and polymer banknotes for extended periods of time following handling and is therefore available for transfer. This transfer then readily occurs, even when contact is brief and involves relatively small forces. A key distinction between the banknote types was that cocaine particulates are more likely to transfer from polymer banknotes due to the lower retention rate of particulates on this surface. Such insights can aid in evaluating the relevance of illicit drug particles identified on items or persons of interest in crime reconstruction approaches.
