Abstract
The ongoing humanitarian aid crisis at the US-Mexico border has experienced an
increase of individuals “Other Than Mexico” apprehended in the past couple of years. In
2019, Mexico was surpassed as the nationality with the most apprehended individuals
reported by the CBP (US Customs and Border Patrol, 2019a). Despite the increase of
Central and South American individuals reported as apprehended, current craniometric
data does not have reference samples of these reported countries. Craniometric analysis
can aid in the identification of presumed migrant remains by estimating the geographic
origin of an individual. Currently, the only reference data available for comparison when
conducting anthropological analysis on migrant includes a “Hispanic” and a Guatemalan
Mayan group. Grouping Latin American individuals under the term “Hispanic” is
problematic as the term does not include all Latin American countries. Therefore, this
project aims to address these problems by looking at craniometric variation from South
American samples in comparison to current Central American reference data. This
research looks at archaeological and modern samples from Colombia, Brazil, Peru,
Guatemala, and Mexico using thirteen ILDs as described by Howells (1973). Results
further demonstrate the need of modern reference samples and further analysis between
country samples and within country samples. Incorporating reference samples of the CBP
reported apprehension can aid in the identification of presumed migrants found in South
Texas and allow for further anthropological, DNA, and isotopic analysis to further
provide a positive identification.
