Jiang Yuan made the fingerprints of the greenhouse arson case over and over again for a week. Now when he saw the newly downloaded fingerprints, a picture appeared in his mind.

The pictures are not the same, but there is a certain degree of similarity. Considering factors such as the deformation of the fingerprints and the sun exposure, Wei Zhenguo said earlier, it is really possible.

Both have their own flaws. It may be difficult to prove that they are the same fingerprint. Merging two fingerprints into one fingerprint is also a very difficult operation.
