Abstract

When death occurs, the supply of adenosine triphosphate through respiration ceases, and rigor mortis begins approximately 20 minutes after death. The underlying mechanisms of rigor mortis and cadaveric spasm are assumed to be similar. However, unlike rigor mortis, cadaveric spasm is a very rare phenomenon in which muscle stiffness develops almost immediately after death. Herein we describe a 27-year-old male with suspected cadaveric spasm. A forensic pathologist concluded that the cause of death was a head injury due to a fall. When the body was discovered, a cigarette remained in the mouth, suggesting a cadaveric spasm. Some opinions deny the existence of cadaveric spasm because there is no precise pathophysiological mechanism to support it. Cadaveric spasm could not be confirmed in the present case; however, while the complete mechanism is unclear, as in this case, it is sometimes difficult to rule out the presence of cadaveric spasm in forensic investigations. Therefore, a comprehensive forensic examination is necessary, and forensic examiners should be cautious.
