  12. Samples Examined and Linkages Over 1,100 illicit fentanyl samples examined 41 Sets of seizure linkages made to date that include: • 73 different cases/seizures • 169 different exhibits • Over 300 kg fentanyl originating from Chinaand Mexico

  13. Cocaine Signature Program Mission Origin Determination by Chemical Analyses • Research Projects • CSP • Operation Breakthrough • Cocaine IRMS • Differentiation of Growing Regions

  14. Cocaine Signature Program History More than 30 years of research producing over 100 scientific publications in peer-reviewed journals
