State of Arizona, Appellee v. Joseph Wesley Gomez, Appellant

Summary

The court held that the Confrontation Clause was not violated when a testifying DNA analyst described profiles generated by non-testifying technicians and offered an independent matching opinion. The analyst had reviewed the technicians’ work, was familiar with the laboratory’s procedures, and personally performed the interpretive comparison. The court also held that no limiting instruction was required because the testimony about the profiles served purposes beyond merely supporting the expert’s opinion.
