Introduction:

- Livor mortis, also known as lividity or postmortem lividity, refers to the pooling of blood in the lowest parts of the body after death.

- Forensic significance: Helps estimate time and circumstances of death.

Understanding Livor Mortis:

- Process: Begins within 30 minutes to 2 hours after death and becomes fully apparent within 6-12 hours.

- Cause: Blood settles in the dependent areas of the body due to gravity and lack of circulation.

Forensic Significance:

- Time of death estimation: Livor mortis patterns can indicate whether a body has been moved after death.

- Determining position: Livor mortis can provide clues about the position of the body at the time of death.

Livor Mortis Examination:

- Assessment: Forensic investigators examine the color, distribution, and fixedness of lividity.

- Fixed lividity: Livor mortis becomes fixed after 8-12 hours, indicating that the body has not been moved.

Limitations and Considerations:

- Factors affecting lividity: Ambient temperature, body position, clothing, and movement after death can affect livor mortis patterns.

- Redistribution: Lividity may shift if the body is moved after livor mortis becomes fixed.

Conclusion:

- Livor mortis is a valuable tool in forensic investigations for estimating time of death and determining body position.

- Careful examination of lividity patterns provides crucial insights into the circumstances surrounding a death.
