Frequently Asked Questions
What is algor mortis?
Algor mortis refers to the postmortem cooling of the body toward ambient temperature, a standard method forensic professionals use to help estimate time since death, especially within the first 24 hours.
Why does ambient temperature affect the formula?
A body cools faster in colder surrounding air, so a different cooling rate constant is used depending on whether the ambient temperature is above or below freezing.
How accurate is this estimate?
Algor mortis estimates are approximate and can be affected by many factors including body size, clothing, humidity, and airflow. Forensic professionals combine this method with other indicators like rigor mortis and livor mortis for a more complete estimate.
Is this formula used in real forensic investigations?
Yes, a version of this simplified cooling formula is a commonly-taught starting point in forensic science, though real investigations use more detailed models accounting for additional environmental factors.
