Continuity mistake: When Dexter is packing kill tools for the road he "packs light" and chooses a knife and hammer. However once he's at the hotel room setting up the kill room he unrolls his entire set of tools like he does at all the other murder room scenes.
Continuity mistake: When Dexter is killing Stan Beaudry, the drop of Beaudry's blood encompasses the width of the blood slide when the two pieces of the slide are pressed together, but then goes to being roughly half the size when the shot changes.
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."
