Final answer:
Dr. Alec Jeffreys did not use traditional fingerprints in policing; instead, he was a pioneer in the field of DNA analysis, developing DNA fingerprinting in 1985 for forensic science, which was distinct from early physical fingerprint identification methods.
Step-by-step explanation:
The first person to use fingerprints in police-related work was neither Alec Jeffreys, John Doe, Jane Smith, nor Michael Johnson. The concept of using fingerprints for identification actually dates back much earlier. However, the technology of DNA fingerprinting was developed by Dr. Alec Jeffreys of Leicester University in the United Kingdom in 1985. Dr. Jeffreys did not use traditional fingerprints in his work; he was a pioneer in the use of DNA analysis for forensic science, as shown by his involvement in solving an immigration case using this technology.
It's important to differentiate between the use of physical fingerprints and DNA fingerprinting. The latter is a genetic analysis that identifies individuals based on their unique DNA profiles, and it was this advancement that Dr. Jeffreys contributed to, not the initial use of fingerprints in policing.
