Rigor Mortis Research Paper

This conclusion lines up with what the textbook states about determining a time of death. The textbook lists many factors that can affect body decomposition including temperature, rainfall, and humidity (Lyman 284). Obviously it would be extremely difficult if not impossible for investigators to factor in all these variables given the fourth months between when the body was dumped until it was found. This makes it clear that investigators could not truly determine an exact time of death.

The CSI arrived at 12:01 PM and the Forensic Investigator (FI) from the ME's Office arrived at 12:21 PM. The death analysis was performed by the FI. At the crime scene, Livor mortis was identified at the victim's back and Rigor mortis is all over the victim's muscles. Based on the information provided by the FI, Dr. Young determined that the time of death (TOD) of the victim is around 11:30 PM on June 16 to 2:30 AM on June 17.

Rigor Mortis on the other hand is the stiffening of the body due to a loss of ATP from the body’s muscles. All of the muscles are affected at the same time. Rigor mortis occurs normally two hours after death. Once in the phase of rigor mortis, it only lasts about anything from eight hours to twelve hours. Many people think that once the body hits rigor, then it is going to stay that way, however it is the opposite. The body eventually returns to a relaxed state where the muscles will lose the tightness and return back to normal. Rigor mortis has good means of determining time of

Thousands of dead seabirds are being washed up on the Alaska shoreline. Scientists estimate that the number of birds who have died since August of last year, all of them belonging to one species known as the common murres, could be as high as 100,000. And the most likely reason for their death is starvation, caused by a sudden collapse in the populations of the fish that form the basis of their diet.

Postmortem hypostasis, body temperature, rigor mortis are the three key indicators to determine the time since death. Hypostasis is characterized by the dark purplish blue color changes on the skin due to pooling of blood. The hue starts to appear within the first two hours after death and then remain permanently after a period of time, usually eight hours after death. With regard to rigor mortis, which also starts to develop within the first two hours, and then the muscles would be fully stiffed in 6-12 hours. Generally, after 36-48 hours, the body would be softer due to the relaxation of muscle. Body temperature should be measured so as to determine how long the person has been dead. The lower the body temperature, the longer the time

A mortgage is a legal agreement by which a bank loans cash at interest in return for taking title of the borrower's property, with the condition that the transport of title ends up noticeably void upon the installment of the obligation.

Firstly after the last breath is taken, the brain waves surge throughout the body. As the brain ceases to send any type of signals to the muscles in the body, they begin to slowly stop working and the body turns to a stiffened state and will stay like this for 4-6 hours. As the body is horizontal the blood pools at the lowest point of the body causing red and purple discoloration; this becomes more apparent in people with lighter skin, which is why in contrast to this, the skin looks a sickly pale. After 6 hours of being deceased the body tissue starts to decompose, this results in a fowl odor lingering from the body. As this is happening the cells inside the body build up with carbon dioxide but eventually the cells burst creating an acidic, blister-like liquid that further breaks down the muscles and tissues inside the body, this causes mass multitude of bacteria that eat away ate the remaining muscles and eventually begins eating away at the flesh; along with other insects and bugs. The bones of the body eventually are broken up by nature itself and turned to dust, creating the prefect nutrients for the soil to become fertile so that other plants can

The other method is to measure rigor mortis which describes the mechanism when the human extremities start to stiffen. It is a natural process occurring in all of us and it is the natural contracting and relaxation of the muscles caused by changes in the body's chemical balances. It usually occurs in the smaller muscles such as those in the face and neck and then reaches the larger ones. Rigor mortis normally begins two hours after death and can last from twenty to thirty hours. Attention should be paid to the misconception that this is a process which does not leave the body because after this timeframe it will. Another important coefficient for estimating time of death is forensic entomology, the study of insects, which will be dealt with

When there is a rapid break down of damaged skeletal muscle tissue the condition is termed as Rhabdomyolysis.

Burial of a body prevents many insects from getting to the body therefore slowing down decomposition. The only bugs known to reach a body once it has been buried are blowfly larvae, flesh fly larvae and coffin flies. (Fraser 2015, Per Comm). Environmental factors can also affect the way insects attend a body. During winter most insect activity is reduced. Sometimes blowflies may not be seen at a body until spring time therefore during colder weather bodies decompose more slowly than during the warmer months. (Fraser 2015, Per Comm). It is important to know the temperature of the crime scene so an accurate time of death can be achieved based on the growth of the insects. If it is cold the insects are more likely to remain smaller for a longer period of time than if

Forensic anthropologists use a number of methods to estimate the age at death for skeletal remains. In general, the methods are based largely upon the morphology of the skeletal elements, that is, the presence of non-metric traits or specific morphological features on each of the bones of the skeleton. These characteristics for example also include the degree of fusion of the proximal and distal epiphyses, fusion of the cranial sutures, dental eruption patterns etc.

Postmortem interval estimation is very important in a suspicious death investigation. Myoglobin is a hemoprotein present in striated muscles of living body. After death, myoglobin is exuded from muscles to blood, tissues and organs. So, the aim of this study was to estimate postmortem interval from myoglobin concentrations in glandular tissues. This study was done on rats to detect the postmortem concentration of myoglobin in pituitary, parotid and adrenal glands at different time intervals. There was a significant correlation between myoglobin concentration in glandular tissues and postmortem interval. By multiple stepwise linear regression analysis, the most predictable model was the combination between pituitary, adrenal and parotid myoglobin concentrations (R2= 0.992). The second predictable model was the combination between adrenal and pituitary myoglobin

forensic anthropology is one of the steps that have a major goal for identifying of skeletal remains includes an assessment specific to the cause and the manner of death [1]–[2][3]. the identity of skeletal remains is an essential part of post-mortem to recognize of biological profile of unknown
