Pallor mortis - paleness occuring 15–120 minutes after the death
Algor mortis - reduction in body temperature following death.
Livor mortis - 20 min to three hours after death, max within 6-12 hours. Heat will speed the process. The settling of blood to the lowest portion of the body.
Rigor mortis - commences after about 3 hours, reaches maximum stiffness after 12 hours, and gradually dissipates until approximately 72 hours (3 days) after death.
Putrefaction - 2 to 3 days to 4 weeks
Decomposition - speed varies greatly
Skeletonization - speed varies greatly
The EMT's noted rigor in her jaw at 6:48 am and therefore did not perform CPR.

Livor mortis (Latin: livor—"bluish color," mortis—"of death"), postmortem lividity (Latin: postmortem—"after death", lividity—"black and blue"), or hypostasis (Greek: "sediment") is one of the signs of death. Livor mortis is a settling of the blood in the lower (dependent) portion of the body, causing a purplish red discoloration of the skin: when the heart is no longer agitating the blood, heavy red blood cells sink through the serum by action of gravity. This discoloration does not occur in the areas of the body that are in contact with the ground or another object, as the capillaries are compressed.
Livor mortis starts twenty minutes to three hours after death and is congealed in the capillaries in four to five hours. Maximum lividity occurs within 6-12 hours. The blood pools into the interstitial tissues of the body.

Rigor mortis, or postmortem stiffening and contraction of all muscles, usually occurs three or more hours after death and can last for approximately 36–48 hours in temperate climates and about 9–12 hours in tropical temperatures. If a murderer moves a body before rigor mortis (RM), the new position will be "frozen" during RM, not the original one that would have characterized the pattern of the body falling at the crime scene. Therefore, the position a body shows during rigor mortis cannot be assumed as the position in which the victim was at the moment of death. The rigor mortis phase is not the best time for the pathologist to determine the cause of death, because several changes take place in the internal muscles, such as the heart and the ocular muscles, which can be misleading. For example, rigor mortis dilates the myocardial (heart) muscles, giving it the appearance of cardiac hypertrophy (enlarged heart). Contraction of the iris muscles also dilates the pupils during rigor mortis.
The factors that interfere with the onset and duration of rigor mortis are temperature, existing antemortem pathologies, age, body muscular mass, and the degree of muscular activity immediately before death. Higher temperatures shorten the time till the onset of rigor mortis and its time of duration. A strong fight or lengthy physical effort before death causes an earlier onset and shorter duration of rigor mortis. Children and older adults have also earlier rigor mortis than younger adults. Generalized infections, or long, debilitating diseases also produce earlier onsets and shorter periods of rigor mortis, whereas extensive antemortem bleeding or death due to asphyxia delays rigor mortis onset.

At 2000 hours rigor mortis was marked in the upper and lower extremities, neck and jaw. Livor mortis was posterior, red and fixed. Both rigor and livor mortis were appropriate for the decedent's position. There was cutis anserina of the legs. There was skin slip with pressure on the lower left eyelid.
