Medico-Legal Investigation of Death Flashcards
Major duties of a forensic pathologist
- To determine cause and manner of death.
- To identify the deceasedif unknown.
- To collect evidence from the body.
- To document injuries or lack of them.
- To deduce how the injuries occurred.
- To document any underlying natural disease.
- To attend scene of crime.
- To determine or exclude other causes of death.
- To provide expert testimony.
The philosophy behind forensic medicine
Applying medical knowledge
and methodology
for the resolution of
legal questions and problems for individuals and societies’.
- Without good legal medicine – there
can never be good justice!
Def of legal medicine
- the application of medical knowledge to the administration of the law,
- and to the furthering of justice and,
- in addition, the legal relations of the medical practitioner
legal medicine in relation to the need for justice
- Its born from the need for justice
- It has had to adapt to a succession
of scientific, technological, sociocultural and legal contexts throughout history. - As a branch of science it is in constant evolution.
- On it depend the honour and freedom of people
Forensic medicine
The Living: Forensic medicine, also known as legal medicine, focuses on applying medical knowledge to investigate crimes involving living persons. This field encompasses:
Clinical Forensic Medicine: Examining victims of assault, domestic violence, or sexual abuse to document injuries and collect evidence.
Forensic Psychiatry: Assessing the mental state of individuals involved in legal cases, determining competency to stand trial, or providing psychiatric evaluations.
Forensic Toxicology: Testing individuals for drugs or alcohol, especially in cases of suspected poisoning or substance abuse.
Age Estimation: Using medical techniques to estimate the age of individuals, often in cases of immigration or human trafficking.
Forensic pathology
The Dead: Forensic pathology is the branch of medicine that deals with investigating deaths, particularly those that are unexpected, unexplained, or suspicious. This field includes:
Autopsies: Conducting thorough examinations of deceased bodies to determine the cause and manner of death.
Postmortem Toxicology: Analyzing tissues and fluids from the deceased to detect the presence of drugs, alcohol, or toxins.
Trauma Analysis: Identifying and documenting injuries to understand the circumstances leading to death, such as in cases of homicide, accident, or suicide.
Time of Death Estimation: Using various methods to estimate the time of death, which can be crucial in criminal investigations.
early example of forensic medicine at the Cape
In 1660, a notable postmortem examination was conducted on the body of a boatswain’s mate. The examination was requested by Jan van Riebeeck and performed by the Senior Ship’s Surgeon, P. Chevalier, in the presence of the Fiscal and surgeon Pieter van Clinckenbergh. The report stated that the jugular vein and carotid artery were severed, leading to death from loss of blood

Primary Medical Cause of Death
The primary medical cause of death is the disease or injury that initiates the sequence of morbid events leading directly to death. It is the starting point of the fatal process.
Example: A fatal heart attack caused by severe coronary artery disease.
Circumstances in Which Death Occurred
The context or situation surrounding a person’s death, often described using terms like “as gathered” or “as informed.” This includes the conditions and events leading up to death as reported by witnesses or discovered during investigation.
Example: A person found deceased in their home after reporting chest pain to a friend the previous day.
Mechanisms of Death
The physiological changes or pathological processes that result in death. These mechanisms explain how the primary cause of death leads to the cessation of life.
Example: Cardiac arrest caused by a heart attack.
Contributing Cause of Death
A condition or factor that contributes to an earlier death but is not the primary cause. It exacerbates the primary condition, accelerating the fatal outcome.
Example: A person with chronic atherosclerosis who dies from carbon monoxide poisoning.
Predisposing Cause or Condition
An underlying condition or circumstance that makes an individual more susceptible to an accident or fatal event.
Example: Alcohol consumption leading to impaired driving and a motor vehicle accident (MVA).
Precipitating Cause
An immediate trigger that precipitates a fatal event, often by inducing stress or excitement in an already vulnerable individual.
Example: A heated argument that triggers a cerebral hemorrhage in a person with high blood pressure.
Terminal Cause of Death
Definition: The final event or complication that directly leads to death, often following an initial injury or disease.
Example: A person with a head injury who develops pneumonia, which ultimately leads to death.
Exclusive (Sole) Cause of Death
A single cause that directly leads to death without any contributing factors.
Example: A stab wound to the heart causing immediate and fatal blood loss.
Manner of death
The manner of death refers to the way in which the cause of death came about. It is categorized into five main types:
Different Courts and Standards of Proof
- Criminal law: ‘Beyond a reasonable
doubt’. - Civil law: ‘On a balance of probabilities’.
- HPCSA: ‘Negligence’.
Criminal Law: ‘Beyond a Reasonable Doubt’:
Definition: In criminal cases, the standard of proof is “beyond a reasonable doubt.” This means that the evidence presented must be so convincing that there is no reasonable doubt left in the mind of the judge or jury about the defendant’s guilt.
Application: This high standard is required because criminal convictions can result in severe penalties, including imprisonment or even the death penalty.
Example: A person is charged with murder, and the prosecution must prove beyond a reasonable doubt that the defendant committed the crime.
Civil Law: ‘On a Balance of Probabilities’:
Definition: In civil cases, the standard of proof is “on a balance of probabilities.” This means that the evidence must show that it is more likely than not that the claim is true (greater than 50% likelihood).
Application: This standard is lower than in criminal cases because civil cases typically involve disputes over rights, obligations, or damages rather than criminal penalties.
Example: A person sues another for breach of contract, and the plaintiff must prove that it is more likely than not that the contract was breached.
HPCSA: ‘Negligence’
Definition: In cases involving the Health Professions Council of South Africa (HPCSA), the standard of proof often revolves around “negligence.” This means that a medical practitioner failed to provide the standard of care that a reasonably competent professional would have provided under similar circumstances.
Application: This standard is used to assess professional conduct and determine whether a healthcare provider has acted negligently.
Example: A patient claims that a doctor’s negligent actions during surgery caused harm, and the HPCSA investigates whether the doctor’s conduct fell below the expected standard of care.
The Old B-1663 Form
The B-1663 form was a standardized document used in South Africa for reporting and certifying the causes of death. It was an important tool for recording information about deaths, including the primary and contributing causes, and ensuring accurate and consistent documentation for legal and public health purposes.
The new DHA-I663
Also known as the Notification of Death/Still Birth form, is a crucial document used in South Africa for reporting and certifying deaths.
This form is part of the administrative process managed by the Department of Home Affairs (DHA) and is essential for the legal registration of deaths.
Identity as Key Section of the DHA-1663 Form
This section captures the personal details of the deceased, including:
Full name and surname.
Date of birth.
Identity number (or passport number for non-citizens).
Residential address.
