Answer: The short answer is yes, it could. but, it would have to be set up to analyze results to differentiate species. The sequencer will report the base pairs for any properly prepared sample, but interpreting the results is a software package. The software is available, but I would think it unlikely that an analysis package used in a forensics lab would have the capability to be so specific. More likely it would report "Non Human Sequences Found."
