Small muscles, such as the jawbone, are usually affected first. Im not familiar with the case you are speaking about of course however I can say that TOD is usually an estimate. Why is it so important to get an accurate estimate of the time of death when someone has died under suspicious circumstances? The key is that the corpse will lose or gain heat until it reaches equilibrium with its environment. Explain your answer. Explain your answer. The post-mortem interval (PMI) is the time interval between when the individual died and when the body was found.
