A New Method for Determination of Postmortem Interval: Citrate Content of Bone*

Abstract: Few accurate methods exist currently to determine the time since death (postmortem interval, PMI) of skeletonized human remains found at crime scenes. Citrate is present as a constituent of living human and animal cortical bone at very uniform initial concentration (2.0 ± 0.1 wt %). In skeletal remains found in open landscape settings (whether buried or not), the concentration of citrate remains constant for a period of about 4 weeks, after which it decreases linearly as a function of log(time). The upper limit of the dating range is about 100 years. The precision of determination decreases slightly with age. The rate of decrease appears to be independent of temperature or rainfall but drops to zero for storage temperature <0°C.     

Short reviews

Abstract

In an attempt to publish some reviews sooner after material comes out, the Bulletin of Concerned Asian Scholars has added this section of short reviews of individual books, movies, TV series, and so on. For more information about short reviews as well as review essays, see the introduction to the list of books to review on p. 92 of this issue.
