Developing Identification Methods for US/Mexico Border Crossing Fatalities and Hispanics

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 identifications 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.

Data collected from the NIJ grant has created new reference data that has been used to create new techniques for sex estimation for individuals considered Hispanic and helped to improve ancestry estimation.  Further, standard data collected on OpID cases adds to this database.
