Forensic anthropologists have long used qualitative decomposition data to estimate the time of death. Linking more quantitative data, such as regional data on the rate of decomposition of remains, with traditional qualitative data could improve time of death estimations. The current study examined the rate of decomposition for a variety of experimental burials in Alberta in order to provide the regional data on decomposition in this area. Twenty-one domestic pigs were buried in 21 pits at the test site during May, June, and August 2002. Following burial, they were excavated and observed over a period of 15 months in Edmonton, Alberta. Observation data recorded at 2 weeks, 5 weeks, 3 months, 1 year, and 15 months were correlated with decomposition stages, time since death, climate data, grave type, clothing, and burial depth among other factors. Results discuss the regional information concerning the stages of decomposition. Factors most contributing to advanced decomposition were climate data, insects, and grave type. Tables, references
