Well what i learned in class is very important to solving crimes, it is called entomology. Entomology helps find out things about a death a that persons body can't say, but the things and insects around it can tell the investigators. For example, a blow flies state and size will give the entomologist a pretty good idea of how long the body has been there. Or where the person was killed if the person was moved from one region to another. We also found out more ways to determine how long the person has been dead.

Rigor mortis is when the body turns hard. can help give an estimated time of death. If the rigor is just in the head and shoulders then the corpse has only been there for a few hours. It it is past the shoulders then the body has been there for at least 5 or more hours. Rigor is when the body starts to harden.

Liver mortis is pooling of the blood in the spot in the body where it is the lowest point. It starts to happen 2hours after death.

Bones help determine the sex,age and height. The size of the pelvis can tell the sex: if it is more than 90degres it is the female. The height just gives you a better understanding of what the person looked like before death occurred. Age is determined by the teeth. Also the length of the bones is what anthropologists use to analyze dead people.
