A case where someone steals a doctor's identity, medical license, and DEA license would not be the jurisdiction of local police like the NYPD. Medical practitioners (doctors, dentists, physician assistants, nurse practitioners, etc.) don't automatically have the privilege to prescribe all drugs. A medical license gives practitioners authority to prescribe any drug that is not a controlled substance. A practitioner needs to get a separate license from the DEA (Drug Enforcement Administration) in order to have the authority to prescribe medications that are controlled substances, like in this case Benzedrine. So if someone were unlawfully prescribing controlled substances by stealing a medical practitioner's identity to fraudulently use that practitioner's DEA license, that crime would be investigated by the DEA and prosecuted by the U.S. Attorney's office, not NYPD narcotics and the New York County DA's office.
