Comparative StudyRadiographic features of intracorporeally smuggled liquid cocaine.
The radiological features of intracorporeally smuggled cocaine powder are well-established. Liquid cocaine is a novel method for intracorporeal drug smuggling. We describe radiological features of liquid cocaine on abdominal plain films and computerized tomographic (CT) scans and compare them to those of cocaine powder. ⋯ Liquid cocaine has several unique imaging features that assist its detection on abdominal plain film. A CT scan can assist detection in inconclusive cases by demonstrating hyperdense irregular packets of liquid cocaine and a "jigsaw" pattern of gas between them.

Case ReportsThree rounds as "tandem bullets": unusual findings in a case of a suicidal gunshot to the head.
We report an unusual case of suicide in which three 7.65 caliber projectiles were found in the single gunshot wound to the head of a 53-year-old man. Based on data collected at the death scene, CT scan, autopsy findings, and ballistics analysis, the events were reconstructed as follows: two 7.65 mm rounds had already been fired from the 9 mm Makarov pistol the subject was using but, being a smaller caliber, the cartridges had slipped forward and lodged within the barrel. When a third 7.65 mm cartridge was chambered and the gun fired for the third time, the nose of the last bullet hit the lodged bullets and all three rounds were propelled out of the muzzle in tandem as a single shot. ⋯ In cases of gunshot wounds where the manner of death is unclear, a number of well-described circumstantial parameters, such as an atypical anatomical location of the gunshot, unusual firearm, or ammunition, as well as ambiguous autopsy findings, can raise doubts about the manner of death. In very rare cases, despite a single entrance wound, two or more bullets are recovered from the body, fired by the same weapon at the same time (the so-called "tandem bullet" phenomenon). Injuries by "tandem bullets" have crucial implications in gunshot deaths because of the mismatch between the number of entrance and exit wounds and the number of bullets found in or near the body.

Comparative StudyAn evaluation of two conducted electrical weapons using a swine comparative cardiac safety model.
Arrest-related deaths proximate to the use of a conducted electrical weapon (CEW) continue to generate controversy despite a better understanding of the multi-factorial nature of many of these deaths. With the rapid adoption of this technology by law enforcement, and the proliferation of companies entering the marketplace, it is important to have a method to assess the relative safety of these weapons. ⋯ Our results suggest that the TASER X2 may have an improved cardiac safety margin over the Karbon Arms MPID as determined by a smaller area of cardiac pacing on the anterior chest in our model. This model seems to offer a reproducible means of comparing the cardiac effects of CEWs.

The excited delirium syndrome (EDS) is a life-threatening condition caused by a variety of factors including drug intoxication and psychiatric illness. Fatal instances of excited delirium frequently come to the attention of the medical examiner/coroner due to the circumstances and potential causes. Excited delirium may include paranoid, aggressive, and incoherent behavior which may lead to an encounter with law enforcement. ⋯ When attempting to determine the proximate cause of death in instances with multiple potential causes, determining the mechanism of death often is useful. As not all causes of death have pathologically-demonstrable mechanisms of death, examination of the circumstances of the death often are diagnostically important. The main goal of the autopsy of deaths suspected to be due to EDS is to identify (or exclude) intervening diseases or injuries sufficient to explain the death in the context of the investigated circumstances.
