Forensic palynology in Canada: an overview with emphasis on archaeology and anthropology

Palynological analysis is shown from published and unpublished Canadian examples to be a useful tool in forensic investigation, although the technique is almost unknown and therefore under-utilized by forensic investigators. The techniques of pollen and spore identification and interpretation are continually improving, indicating that the potential for forensic applications is real. Focus in this paper is on an updated interpretation of palynological data that was presented during a trial involving a scientific test of oral history as part of a claim for aboriginal title to a large area of British Columbia (BC) (Delgamuukw versus the Queen). Although the original decision in British Columbia Supreme Court was decided in favor of the government defendants, an appeal to the Supreme Court of Canada overturned the original decision, and established new principles and rights for aboriginal peoples.     

Personal identification of cold case remains through combined contribution from anthropological, mtDNA, and bomb-pulse dating analyses

In 1968, a child's cranium was recovered from the banks of a northern Canadian river and held in a trust until the "cold case" was reopened in 2005. The cranium underwent reanalysis at the Centre for Forensic Research, Simon Fraser University, using recently developed anthropological analysis, "bomb-pulse" radiocarbon analysis, and forensic DNA techniques. Craniometrics, skeletal ossification, and dental formation indicated an age-at-death of 4.4 ± 1 year. Radiocarbon analysis of enamel from two teeth indicated a year of birth between 1958 and 1962. Forensic DNA analysis indicated the child was a male, and the obtained mitochondrial profile matched a living maternal relative to the presumed missing child. These multidisciplinary analyses resulted in a legal identification 41 years after the discovery of the remains, highlighting the enormous potential of combining radiocarbon analysis with anthropological and mtDNA analyses in producing confident personal identifications for forensic cold cases dating to within the last 60 years.
