The insulin pump as murder weapon: a case report

Microprocessor-controlled insulin pumps designed for continuous delivery of short-acting insulin analogs into subcutaneous tissues offer several important potential benefits for diabetic patients. The delivery of other substances using these systems is technically feasible. We present a case of homicide involving lethal doses of etomidate and atracurium injected via the victim's insulin pump. This unique situation could be encountered by homicide investigators more frequently as the popularity of these systems continues to grow.     

Identification of an alleged offender of murder by VNTR analysis: case report

DNA typing was used to demonstrate that three human body pieces found disposed of in the countryside around Athens and the suspicions about the perpetrator's identity were connected. Reverse paternity testing was attempted by comparative typing of three variable number tandem repeats loci in the remains, as well as in the presumptive parents and sister of the decedent, demonstrating Mendelian inheritance of the alleles of the loci analyzed. Confronting the results of the abovementioned analysis, the suspect accepted the accusation.     

Hair as a source of forensic evidence in murder investigations

Obtaining palynological and other botanical evidence from murder victims is becoming part of routine mortuary protocol in the United Kingdom. Forensic pathologists are often keen to cooperate in the collection of classes of material that have, in the past, been considered to be of little importance in criminal investigation. Work over the last eight years has demonstrated the great value in scrutinising cadavers for the presence of plant material and/or soil stains. Macroscopic plant remains and palynomorphs (pollen, spores and other microscopic entities) retrieved from skin and hair have allowed the differentiation of murder scenes from places of eventual deposition. Furthermore, although the opportunity has not yet presented itself, obtaining palynological evidence from the hair of suspects is feasible. During an offence, the offender might have had physical contact with foliage or the ground. Pollen and spore assemblages picked up by hair during that activity might provide forensic evidence for contact. Brief details of some aspects of case histories are presented to demonstrate the value of sampling cadavers. One case has been through the courts while the other is ongoing and, therefore, cannot be identified.     

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.     

The evidence notwithstanding--a case report on a rape.

This report concerns the rape of a woman by a stranger. The complainant stated that, during the course of the rape, penetration took place without ejaculation: these details were later confirmed by a suspect. This suspect, who was identified by the complainant, confessed and was convicted. Laboratory findings, however, indicated that the suspect could not have been the source of the semen found on the complainant's underpants. Further, a vaginal swab taken from the complainant contained intact sperm cells, an indication of a recent sexual contact. In spite of the presence of semen on the underwear which could not have come from the suspect, and the nonoccurrence of an ejaculation during the rape, the complainant maintained that she had not had a sexual contact for a month prior to the rape. This apparent contradiction and its implications are discussed.     

Child abduction murder: the impact of forensic evidence on solvability

This study examined 733 child abduction murders (CAMs) occurring from 1968 to 2002 to explore the influence of forensic evidence on case solvability in CAM investigations. It was hypothesized that the presence of forensic evidence connecting the offender to the crime would enhance case solvability in murder investigations of abducted children. This study examined the impact of CAM of different types of forensic evidence and the impact of the summed total of forensic evidence items on case solvability by controlling for victim age, victim race, victim gender, and victim-offender relationship. Time and distance theoretical predictors were also included. Binomial logistic regression models were used to determine whether forensic evidence was a critical solvability factor in murder investigations of abducted children. This research indicated that, while forensic evidence increased case solvability, the impact of forensic evidence on solvability was not as important as other solvability factors examined.     

The use of the subculture of violence as mitigation in a capital murder case

This paper examines the role a sociologist in a capital murder case involving a defendant who was black and a victim who was a white on-duty police officer. The author of this paper testified in this specific case and has worked as a sociologist in over 60 capital murder cases. The use of the subculture of violence as mitigation is presented.     

Bayesian framework for the evaluation of fiber evidence in a double murder--a case report

Fiber evidence found on a suspect vehicle was the only useful trace to reconstruct the dynamics of the transportation of two corpses. Optical microscopy, UV-Vis microspectrophotometry and infrared analysis were employed to compare fibers recovered in the trunk of a car to those of the blankets composing the wrapping in which the victims had been hidden. A "pseudo-1:1" taping permitted to reconstruct the spatial distribution of the traces and to further strengthen the support to one of the hypotheses. The Likelihood Ratio (LR) was calculated, in order to quantify the support given by forensic evidence to the explanations proposed. A generalization of the Likelihood Ratio equation to cases analogous to this has been derived. Fibers were the only traces that helped in the corroboration of the crime scenario, being absent any DNA, fingerprints and ballistic evidence.     

Reduced punishment in Israel in the case of murder: bridging the medico-legal gap

The psychiatrist's assessment of criminal responsibility of an accused in court for an act of crime has always been a matter of great difficulty. In 1997, clause 300a was incorporated into the Penal Code of Israel, thereby permitting a more lenient punishment for murder than mandatory life imprisonment. The clause includes the definition of what is meant by "severe mental disorder" and "significantly restricted capacity" by the defendant to understand the criminal nature of his or her act and to refrain from committing it. Usage of the concepts "disorder" and "significantly restricted capacity" in addressing the issue of diminished responsibility of the mentally ill is new to the Israeli legal code. The emergence and evolvement of the above concepts are presented through a historical review of the Israeli encoded law concerning mental illness, analyzed from a psychiatric perspective.     

Effects of psychopathy and violence risk testimony on mock juror perceptions of dangerousness in a capital murder trial

The recent introduction of the Psychopathy Checklist-Revised (PCL-R) into the sentencing phase of capital murder trials has heightened concerns about the potentially prejudicial impact of such information on jurors, who might give disproportionate weight to this diagnosis when determining whether a defendant is a “continuing threat to society”. To investigate this issue, 238 undergraduates read a case summary based on US v. Barnette ( ), in which prosecution testimony was presented regarding the presence of a mental disorder (psychopathy, psychosis, or no disorder). Compared to the “no disorder” condition, participants rated psychopathic defendants as more likely to be violent in the future, even though testimony related to level of risk (high or low) was held constant. The difference in perceived dangerousness across the psychopathy and no disorder groups was particularly pronounced when the experts described the defendant as being at low risk. A similar pattern of effects was noted for the psychosis condition, suggesting that the impact of mental disorder testimony on perceptions of dangerousness may not necessarily be specific to the PCL-R.     

False rape: a case report

A 16-year-old girl was admitted to the emergency department for sexual assault. The forensic examination revealed genital lesions of an age that were incompatible with her statements. She also presented extragenital lesions that resembled self-inflicted lesions. The reports of false rape allegations in the literature have all dealt with the motivations of the false victims. This case report is a reminder that an allegation of rape can be considered only on the basis of proof and not on speculation.     

Caffeine fatality: a case report

A case of fatal caffeine toxicity due to suicidal ingestion of a "look-alike" illicit drug is reported. Caffeine concentrations were determined by high pressure liquid chromatography (HPLC) with the brain having the highest level reported in the literature to date. Also, the blood concentration of caffeine was one of the highest among the cases reported. A literature review of caffeine fatalities is presented.     

Identification of a phosphoglucomutase 1 (PGM 1) variant in a case of murder/suicide

A murder/suicide case is reported in which a phosphoglucomutase (PGM) 1*W9 variant was detected in a woman, her child, and from blood collected at the scene.     

Human cannibalism: a case report

Human cannibal cases are relatively rare in modern civilized societies. We report a single case of familial cannibalism that occurred in Oklahoma in 1977. The investigation posed unique problems in pathology, psychiatry, criminalistics, and serology.     

Child barbarity and torture: a case report

Penile strangulation with a strand of hair, acting as a tourniquet, and perforation of the eyes with a knife are uncommon accidental injuries in children. In such a situation, a mistreatment must be evoked. We present a case of barbarity and torture involving a young boy 3 years old. He was a victim of penis strangulation and perforation of the eyes, performed on previous surgical and infectious lesions. The mistreatment was performed by his mother's boyfriend. The perpetrator used the previous lesions to hide his misdeed. This amazing case of mistreatment points out the violence of the wounds and their being performed on previous lesions.     

An already archived latent fingerprint as a DNA source for STR typing in a murder case

Former studies have shown that even a single skin contact, resulting in a latent fingerprint, can transfer enough DNA for genetic analysis. However, up to now latent fingerprints have usually not been used for DNA typing. In the present case the smeared trace of a hand was found in the suspect's car and archived. As it could not be evaluated in a classical manner, the evidence had to be examined by molecular genetic methods. DNA was extracted and typed in five different STR loci. Based on the yielded results, the significance of the findings is discussed.
