After high-profile events involving firearms, gun violence often becomes the center stage of public discourse with national media attention, overshadowing less common causes of homicidal deaths, such as sharp force injury, blunt trauma, and asphyxia. A retrospective analysis of all cases referred for medicolegal autopsy to the Medical and Forensic Autopsy Division of the Department of Pathology and Laboratory Medicine at the Medical University of South Carolina from 2013 to 2018 documented 793 deaths where the manner was classified as homicide. Of these, 18% (144) of the deaths were caused by non-firearm-inflicted injuries.

Misoprostol is a prostaglandin analog commonly used to induce termination of pregnancy. Clandestine home terminations complicate forensic fetal autopsy when a history of misoprostol use is withheld and the gross and histologic findings are sparse, as is often the case. One hundred thirty-two placentas with no vaginal misoprostol use, low-dose misoprostol use, and high-dose misoprostol use were reviewed for the presence, volume, and locations of microcrystalline cellulose and crospovidone, common tablet fillers in misoprostol tablets.

Diffuse Large B-cell Lymphoma, the most common adult non-Hodgkin lymphoma, is a proliferative neoplasm of enlarged B cells. Patients may be asymptomatic on presentation, but if present, symptoms often correlate with direct organ dysfunction resulting from the site of involvement. While the gastrointestinal system is the most common site of extranodal involvement, virtually any part of the body can be infiltrated by malignant lymphocytes.

Vitreous fluid sampling for postmortem chemistry analysis is discouraged in pediatric forensic cases involving head trauma due to the risk of introducing retinal artifacts. Aqueous fluid is physically separated from the posterior chamber of the eye, and therefore, unlikely to produce vitreal artifact when sampled. Analysis of aqueous fluid is therefore proposed as a substitute for vitreous.

Loperamide is an over-the-counter, μ-opioid receptor agonist commonly used as an antidiarrheal agent. Loperamide was thought to have minimal abuse potential due to its low bioavailability and limited central nervous system activity; however, there have been increasing reports of loperamide misuse in supratherapeutic doses to achieve euphoria and/or avoid opioid withdrawal. A literature review suggests a rise in loperamide abuse was inevitable, with substantial increases in reported cases over the last decade.

Respiratory pathogens have been detected in forensic investigations using multiple techniques; however, no study has examined the use of automated, nested, multiplex polymerase chain reaction (ANM-PCR), commonly used in living patients, in the forensic setting. This retrospective study assessed the utility of ANM-PCR in detecting respiratory pathogens in the pediatric forensic setting. Respiratory samples from 35 cases were tested for up to 20 respiratory pathogens.
