Q: Did your lab conduct testing on evidence from the crime scene in this case?

Q: Tell the jury what types of crime scene evidence you tested and whether you compared that against the DNA of any suspect?

Q: And were you, in fact, able to identify the person who left that evidence at this crime scene?
