Skeletons as Forensic Evidence
Cold Case Files are records kept for criminal cases that were never solved, often after several years. In some cases, however, a murder case may go years before it is even discovered. In these cases, most portions of the body will have long since either decayed or have been scavenged. The one portion of the body that takes the longest to decay is the skeleton. These cases would be, uh, cold, but in a different way . . . A person who studies skeletons in order to determine information about the person before she/he died is called a Forensic Anthropologist.
Despite the neglect the dead body endures, there are still quite a number of things that one can learn. First of all, in the area of the skull, one can determine many things. In terms of infants, we can determine the age, in weeks, fairly accurately by examining the development of the skull:

32 weeks
Notice, apart from the difference in size, how the fontanels (the soft spots that ultimately become the sutures, or fixed joints between the bones in the skull) change over time, gradually becoming smaller. One must, however, be careful. Take the following two images, and try to figure out the approximate age of the second image, after examining the first image.
Aged 31 weeks, 32 weeks, and 40 weeks (full term)
