Project Identification: Developing Accurate Identification Criteria for Hispanics

National Institute of Justice Award No. 2008-DN-BX-K464

 In 2008 I received funding from the National Institute of Justice to collect data on undocumented border crossing fatalities (UBCs) at the Pima County Office of the Medical Examiner (PCOME).  Because the PCOME has a high rate of positive identificaitons for the UBCs and because most of their UBCs are from Mexico, it allowed me to create a osteometric database and can be used to further research and development in forensic anthropology.

The specific goals of the grant were to  1) to obtain cranial and postcranial skeletal measurements from individuals from Mexico to establish a database of available reference data for further research and development; 2) to create sectioning points and classification functions for population-specific sex estimates applicable to the majority of Hispanics within the United States; and 3) to utilize traditional and geometric morphometric methods with the new reference data to explore morphological variation of among Mexicans, American Blacks, and Whites, to provide better classification accuracy in ancestry estimation.
