Fatal Dog Maulings in Colorado: A Forensic Case Series

Lethal dog attacks, though comparatively uncommon, are a serious forensic, public health, and medico-legal problem. Our case series explores three lethal canine attacks occurring in the first months of 2025 in the state of Colorado as a way of better understanding canine-mediated mortality. Autopsy and investigative reports were analyzed for three adult victims who were killed over six weeks as a result of dog attacks. Cases were identified through review of official coroner autopsy records, with inclusion limited to deaths certified as due to canine mauling; all other cases were excluded. Demographic data, scene context, and injury findings were extracted from the autopsy reports and investigative files. Comparative analysis was conducted to assess similarities and differences in injury distribution, environmental context, and contributing health factors. Case 1 involved a 76-year-old woman with dementia, fatally attacked by her own 14 dogs at home, suffering exsanguination from femoral artery trauma. Case 2 concerned a 68-year-old woman with multiple comorbidities, found with extensive defensive wounds and avulsion injuries in a suspected feral or uncontained canine attack. Case 3 described a 57-year-old man fatally mauled while walking his dog, with major scalp avulsion and bite injuries inflicted by two pit bulls. All deaths were certified as accidental. Common forensic findings included patterned puncture wounds, soft tissue gouging, and circumferential limb injuries. Defensive wounds were present in two of the three cases. Scene contexts ranged from domestic residences to public areas, with both owned and unrestrained dogs involved. Here, the volume of cases in a short period of time demonstrates the forensic significance of the determination of canine injury patterns, specifically among susceptible victims and street canine populations. This comparative analysis provides insight into wound morphology, victim response, and issues involving multi-canine attack scenes. These findings may have an impact on future guidelines of forensic investigation, animal control laws, and health education.
