The Impact of Victim Demographics on Case Outcomes in Delinquency Proceedings: An Empirical Test

While the impact of the defendant's sex and race on processing decisions is well researched, less is known about the impact of the victim's sex and race on juvenile court decision making. Using data from the juvenile court in St. Louis, Missouri, this study explores direct and interactive effects of the victim's sex and race on outcome decisions for juvenile offenders. Findings suggest that legal differences account for most of the observed differences in detention, commitment and adjudication among the sample studied.     

Sudden Death Due To Acute Cocaine Toxicity—Excited Delirium in a Body Packer

Excited delirium denotes a life-threatening medical condition characterized by the acute onset of agitated and violent behavior that often results in a sudden and unexplained death. Cocaine-induced excited delirium refers to fatal cocaine intoxication with the following symptoms occurring sequentially: hyperthermia, delirium with agitation, respiratory arrest, and death. We present a case of cocaine-induced excited delirium in a cocaine “body packer” or a “mule”, specifically an individual who attempts to smuggle cocaine within the body. Investigators at the scene initially suspected homicide due to the victim's sharp and blunt force injuries. Three rubber packets containing cocaine were removed from the victim's rectum. Blood toxicological analysis revealed an alcohol concentration of 0.016 g/100 and cocaine >1 mg/L. The forensic pathologist should consider cocaine-induced excited delirium when an individual exhibits aggressive behavior, unexpected strength, and resistance to pain who dies suddenly. Further analysis should be performed during the scene investigation and autopsy for evidence of body packing.     

A Rapid and Efficient Method for Evaluation of Suspect Testimony: Palynological Scanning

A rapid method for evaluating suspect testimony is valuable at any stage in an inquiry and can result in a change of direction in an investigation. Rape cases, in particular, can present problems where a defendant renders DNA analysis redundant by claiming that the claimant consented to have sexual relations. Forensic palynology is valuable in confirming or eliminating locations as being crime scenes, thus checking the testimony of both parties. In contrast to some forensic disciplines, forensic palynology can provide critical information without time-consuming full analysis. Two cases are described where the palynological assemblages from comparator samples of pertinent places were compared with those obtained from clothing of claimants and defendants. The results of rapid microscopical scanning of relevant preparations led to early confessions, thus obviating the need for costly analyses and protracted court proceedings. A third case demonstrates the unbiased nature of this technique where a man, although innocent of any offense, lied about having visited the crime scene for fear of prosecution. This highlights the need for sensitive policing in claims of rape.     

Ancestry and BMI Influences on Facial Soft Tissue Depths for A Cohort of Chinese and Caucasoid Women in Dunedin,New Zealand

This study measured and assessed facial soft tissue depths (FSTDs) in adult female Chinese and New Zealand (NZ) Europeans (Caucasoids). Ultrasound was used to obtain depths at nine landmarks on 108 healthy subjects (51 Chinese, 57 NZ European), erect positioned, of same age group (18–29 years). Height and weight were also recorded. Statistical analysis focused on comparison of tissue depth between the two ancestry groups and the influence of Body Mass Index (BMI) (kg/m²). Results showed mean depth differences at Supra M2 and Infra M2 landmarks significantly greater for Chinese than Caucasoid women for all three BMI Classes (BMI <20, 20 ≤ BMI < 25, 25 ≤ BMI < 30), even BMI <20. For both groups BMI positively correlated with FSTD values at all landmarks except Labrale superius. This study enabled ancestry and BMI influence on FSTDs to be observed and compared for two distinct groups. Results add to knowledge about facial tissue depth variation.     

Copper toxicity following massive ingestion of coins

Two hundred seventy-five United States coins were discovered in the stomach of a mentally disturbed individual at autopsy. Many coins containing copper were corroded by prolonged contact with gastric juice, with subsequent absorption and deposition of copper in the liver and kidneys. The patient died from complications related to the acute toxic phase of chronic copper poisoning. A discussion of the case, foreign-body ingestion, gastric bezoars and the mechanism of copper toxicity is presented. To our knowledge, this is the first death due to copper intoxication following a massive ingestion of coins.     

High cyanide level in a homicide victim burned after death: evidence of post-mortem diffusion.

Elevated levels of carbon monoxide and cyanide serve as evidence of intravital burning in fire victims. Hydrogen cyanide is released by combustion of nitrogen-containing organic material such as plastics and wool. We present a case of a man who died of haemopneumothorax caused by a stab wound. According to several eye witnesses the body was wrapped in a plastic sheet and burned 2 days after death with the aid of gasoline. No coal pigment was observed in the mucosa of the upper airways at autopsy. The blood sample taken from the pulmonary vessels 6 days after death disclosed a level of blood carboxyhaemoglobin of 4% and of blood cyanide of 10 mg/l. The low carboxy-haemoglobin level was consistent with the smoking habits of the victim. The thoracic cavity had been opened by burning of the intercostal soft tissue. This allowed hydrogen cyanide gas to enter the thoracic cavity and diffuse into the blood probably causing the high blood-cyanide level.
