STRmix is software used by the NYC Office of Chief Medical Examiner to interpret complex DNA evidence from crime scenes, including samples that contain DNA from more than one person. It uses probabilistic genotyping — a statistical method that generates millions of possible DNA profiles — to calculate the likelihood that a given person contributed to a DNA mixture. The results are used to support or challenge identifications in criminal investigations and court proceedings.
