•This is the first STR report of a southern Mexican-Mestizo population (state of Guerrero).•The reported allele frequencies and forensic parameters validate the use in forensic casework.•Based on 15 STRs, we detail the genetic structure of Mexican Mestizo populations.•Three main Mexican population clusters are concluded: Northwest, Center-South, and Southeast. Allele distribution and forensic parameters were estimated for 15 STR loci (AmpFlSTR Identifiler kit) in 251 Mexican-Mestizos from the state of Guerrero (South, Mexico). Genotype distribution was in agreement with Hardy–Weinberg expectations for all 15 STRs. Similarly, linkage disequilibrium test demonstrated no association between pair of loci. The power of exclusion and power of discrimination values were 99.999634444% and >99.99999999%, respectively. Genetic relationship analysis regarding Mestizo populations from the main geographic regions of Mexico suggests that the Center and the present South regions conform one population cluster, separated from the Southeast and Northwest regions.
