ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONapproximately 20 hours before the measurements were taken at 18:15on May 2. Thus, the time of death was approximately 10 PM on May1.”• The twelfth item is optional but shall appear only if DRDE is present inthe field. It is subject – death age estimate text/ DEAT. It is enteredin UNICODE and a typical entry may be “DCIA {dental cementumincrement analysis} was performed on the left mandibular secondpremolar. The tooth was embedded in epoxy, sectioned, and mountedto a glass slide ground and polished and examined under 10, 20 and40X magnification under polarized light. Subject estimate to be 23.5 to24.5 years based on DCIA.” 1408.12.7 Field 12.007: Original dental encoding system information /ODESThis field is used to describe the data collection schema that was used for theoriginal recordation of dental information. It is a mandatory field if Field 12.010:Tooth data detail / TDD appears in this record. Otherwise this field shall not bepresent in the record. ODES need not be a forensic data system or a systemcapable of formulating an ANSI/NIST-ITL conformant record or transaction. Thepurpose of this field is to specify the rules and definitions that were used tospecify the original data collection.* The first information item is mandatory. It is the original systemname code / OSNC. The code is selected from the following list:EDRFastIDNamUsElectronic Dental Record SystemInterface for completing the INTERPOL DisasterVictim Identification forms 141The National Missing and Unidentified PersonsSystem 142occurs as body temperature changes after death occurs. There is usually decline intemperature until the body reaches the ambient temperature. According to the seasons andthe geographical area, the ambient temperature may vary widely and should be aconsideration. Using the Glaister equation: 36.9ºC (98.6ºF) minus the rectal temperaturedivided by 1.5 will give the approximate hours elapsed since death. Then, as decompositionoccurs, the temperature of the body tends to increase. The rate of decomposition willdepend upon local conditions, for example, sun, water, or ice.” This book also describesLivor mortis and Rigor mortis in estimating time of death.140See: Wedel V, Found G, Nusse G A 37-Year-Old Case Identification Using Noveland Collaborative Methods, Journal of Forensic Identification, Vol. 63.
