Thirteen years ago, a highly influential murder case occurred in Qianzhou City.
A high school student, after finishing evening classes, was robbed and murdered at his home.
The amount stolen was only 500 yuan.
Police found the murder weapon at the crime scene, a fruit knife from the student's home.
A severely deformed bloody fingerprint was discovered on the knife handle.
However, the deformation of the fingerprint was too severe and the technology at the time was limited, so it could not be successfully identified right away.
After that, it entered the Provincial Fingerprint Database Battle Repository, and it wasn't until now that it was discovered by Lu Chuan.
Every time the provincial department holds a fingerprint battle, they set up a hero list in the system to motivate the dozen or so experts to excel beyond each other.
Everyone's name is on it, and solving a case accumulates corresponding points.
For instance, solving a murder case gives ten points.
