Background and Clinical Significance: Fatal attacks by domestic dogs, particularly against familiar owners, are rare but represent a significant forensic and public health concern. Understanding the dynamics and forensic features distinguishing predatory aggression from postmortem scavenging is essential, especially when cases involve large breeds and vulnerable individuals, such as the elderly. Case Presentation: An 82-year-old man was found dead in his home, presenting extensive mutilation of the head and neck. He lived with his daughter and her four-year-old male German Shepherd. The dog exhibited blood and tissue residues on its mouth, forelimbs, and abdomen. Autopsy findings indicated death due to hemorrhagic shock from deep cervical and facial vessel lacerations. There were no defense wounds or classic bite marks; however, massive excision of musculocutaneous tissue from the neck to the scalp suggested active predation rather than postmortem scavenging. The facial and cervical soft tissues were completely avulsed, exposing deep anatomical structures and causing the loss of the right eye and dental elements. No signs of third-party involvement, intrusion, or external aggression were identified, and the dog appeared healthy and unrestrained. Conclusions: The findings support the theory of a fatal attack by the household German Shepherd occurring shortly after the victim’s meal. This case underscores the potential for lethal aggression in domestic dogs toward familiar humans, even in the absence of provocation or prior behavioral concerns. It highlights the importance of awareness and preventive measures when managing large, powerful dog breeds in environments with elderly or otherwise vulnerable individuals.
