Study Notes
Forensic Pathology
- Forensic pathology does not involve the study of mental health, environmental, or occupational health.
- The main finding that forensic pathologists are particularly interested in is the cause and manner of death.
Death Classification
- Natural deaths are those caused by disease or natural processes, whereas unnatural deaths are those caused by external factors such as trauma, poisoning, or homicide.
Rigor Mortis (RM)
- Temperature is a factor that can influence the period of development of rigor mortis.
- Rigor mortis typically reaches its maximum peak around 12-18 hours after death.
- Studying the posture of a deceased body in relation to rigor mortis helps determine if the body was moved after death.
- Rigor mortis can be manipulated by moving the body, but this may not always be detectable.
- Cadaveric spasm is a phenomenon that is not related to rigor mortis.
- Heat stroke can cause a stiffness/rigidity more intense than rigor mortis.
Post-Mortem Changes
- Cadaveric spasm (CS) occurs at the moment of death and is characterized by instantaneous rigidity.
- A forensic pathologist studies post-mortem changes such as rigor mortis, livor mortis (hypostasis), and algor mortis to determine the time of death.
- If an obvious weapon is found at the scene of death, a forensic pathologist should not touch or move it.
Hypostasis (Livor Mortis)
- Hypostasis is the purplish-red discoloration of the skin due to gravity-dependent blood pooling.
- The cause of the purplish-red discoloration in hypostasis is the accumulation of deoxygenated hemoglobin in the blood.
- Hypostasis reaches its maximum peak around 8-12 hours after death.
- The blanching test is used to determine fixed hypostasis, which helps determine the length of time the body has been in a certain position.
Death Scene Investigation
- The role of a forensic pathologist at the scene of death is to observe and document the body and surroundings to aid in determining the cause and manner of death.
- Placing paper bags over the hands of a deceased individual helps preserve evidence, such as skin cells or other trace materials, under the fingernails.
- Examining the position of bullet holes in clothing helps determine the trajectory of the projectile.
