Time of Death Based on Algor Mortis and Rigor Mortis

This occurs 2-4 hours after death, where the blood pools due to gravity. The area affected is a bluish-red color.

• rigor mortis

• algor mortis

• livor mortis

The cooling of body temperature after death is:

• algor mortis
• livor mortis
• rigor mortis
• pallor mortis

The process that causes the muscles in the body to stiffen resulting in rigidity after death is called

• algor mortis

• rigor mortis

• livor mortis

Maximum rigor mortis occurs

• between 2-4 hours

• 2-6 hours after death

• 12 hours after death

• 48 hours after death

Rigor mortis starts at the feet and moves up the body.

• True

• False

Estimate the approximate time of death for the following situation:

A body was found with no evidence of rigor.

• 2 - 6 Hours

• 8 Hours

• Less than 2 Hours

• More than 10 Hours

Under normal circumstances, approximately how many degrees will a body cool during the first 12 hours?

• 0 degrees

• 2.5 degrees

• 1.4 degrees

• 5 degrees
