We report a case of a 51-year-old male who experienced fatal pancytopenia following an MTX medication error during treatment for rheumatoid arthritis. His blood MTX concentration measured 0.04 μmol/L 11 days after discontinuation. Postmortem examination revealed MTX-related toxicity in multiple organs, including the liver and intestines. The spleen showed a prominent increase in plasma cells, including numerous Mott cells. Forensic analysis established the cause of death as acute MTX intoxication, directly stemming from a chain of medical negligence involving prescribing, verification, and administration failures. This case underscores the necessity of rigorous therapeutic drug monitoring, individualized dosing, and robust systemic safeguards to prevent iatrogenic fatalities, highlighting its critical medicolegal and educational implications for forensic and clinical practice.</div></div>","PeriodicalId":16098,"journal":{"name":"Journal of forensic and legal medicine","volume":"120 ","pages":"Article 103159"},"PeriodicalIF":1.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147792932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through a review of 2586 homicide cases adjudicated by Spanish courts, of which 278 (10.75%) involved perpetrators with mental disorders, the distinctive characteristics of these cases were examined. Most involved lethal attacks against family members, with 26.1% constituting parricides. A key finding was that these victims received compensation in only a small number of cases, a disadvantage largely attributable to the intrafamilial nature of most incidents. A further shift in the victimization paradigm may therefore redirect attention toward the specific characteristics of this form of victimization—frequently experienced within the perpetrator's immediate family circle—and promote a more preventive, victim-oriented institutional and professional response to such cases.</div></div>","PeriodicalId":16098,"journal":{"name":"Journal of forensic and legal medicine","volume":"120 ","pages":"Article 103173"},"PeriodicalIF":1.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147995874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All decedents were male, and all ligatures were horizontally oriented. The manner of death was classified as suicide in 15 cases and undetermined in one. Notably, one quarter of cases lacked petechiae, explained by the highly constrictive nature of zip ties and their ratchet locking mechanism. In half of the cases, neck compression resulted from a single ligature formed by one heavy-duty zip tie (6 cases) or several smaller zip ties interconnected to create one ligature (2 cases). The remaining half of the cases involved multiple zip tie ligatures. Most cases (14/16) demonstrated congestion of the head and neck above the ligature mark, occasionally accompanied by ear or nose bleeding. Review of previously published cases revealed similar findings, except for one reported double homicide involving an adult female and her child, a vulnerable population as further corroborated by several news stories. This study emphasizes the importance of recognizing the unique properties of zip ties, particularly their ratchet mechanism, when evaluating ligature strangulation. Without such awareness, the absence of petechiae or congestion may lead to diagnostic uncertainty and the mistaken assumption that neck compression did not contribute to death. One case involving an elderly male showed neither congestion nor petechiae, raising the possibility of reflex cardiac arrest triggered by carotid sinus stimulation.</div></div>","PeriodicalId":16098,"journal":{"name":"Journal of forensic and legal medicine","volume":"120 ","pages":"Article 103130"},"PeriodicalIF":1.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147848025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although dual-energy X-ray absorptiometry (DXA) scans of the distal 1/3 of radius and ulna are widely used in large-scale osteoporosis screenings, forensic studies leveraging such data remain scarce. This study utilized a retrospective dataset (spanning ages 12-96) of 5,134 DXA scans from the distal 1/3 radius and ulna. We analyzed these DXA scans with metadata, including sex, body mass index (BMI), and osteoporosis diagnoses, to train machine learning models. Linear regression (LR), support vector regression (SVR), random forest regression (RFR), XGBoost (XGB), and LightGBM (LGBM) models were optimized via Bayesian cross-validation. Results indicate that the simplest model constructed solely based on <em>BMD data + Diagnoses</em> showed good performance with a mean absolute error (MAE) of 2.40 years. The best-performing model was the RFR model built using the combination of <em>Female + Diagnoses</em>, with an MAE of 2.18 years. When only considering BMI, the best model was the RFR model for the <em>Normal weight + Diagnoses</em> combination, with an MAE of 2.54 years.
