Chapter 181: The Old Profession

Solving cold cases through fingerprint analysis had always been Jiang Yuan's forte.

The plaque commemorating his second-class meritorious service was still basking in the sun at his front door, polished to a shine by his proud father every single day.

Having worked on so many cold case fingerprints, Jiang Yuan felt there was a match as soon as he saw the bloody fingerprint on the leather jacket.

This was a kind of confidence based on personal ability.

Firstly, the clarity of a blood fingerprint was usually passable. Of course, this fingerprint had been found on a leather jacket, so its clarity was slightly compromised, but it was still much better than the condition of most latent sweat fingerprints.

Secondly, although the fingerprint was only one-third the normal size and lacked a center, it had a fingertip. This condition was very personalized.
