Assessing the FBI ’s Native American STR database for random match probability calculations

The impact of forensic DNA evidence in casework lies in its ability to generate robust random match probabilities (RMP) and/or likelihood ratios (LR) that are precise. These statistics are calculated using population allele frequencies generated from the Federal Bureau of Investigation ’s (FBI) Combined DNA Index System’s (CODIS) core short tandem repeat (STR) markers. Recently, the number of CODIS core STRs was expanded from 13 to 20 loci to increase the power of discrimination and compatibility internationally while also decreasing adventitious matches [1].
