When Sun Jun and his team were handling the Wang Huifang murder case, Lu Chuan was still working on the fingerprint identification analysis on his side.
Even though the fingerprints were relatively clear due to the bloodstains, they were too fragmented for a complete analysis, so Lu Chuan had to resort to similarity analysis for manual identification.
It was Lu Chuan's third time refreshing the system page and adjusting the fingerprints for system analysis.
The broken fingerprints not only failed to provide consecutive feature points, but were also few in number, adding to the difficulty of Lu Chuan's analysis.
Ultimately, the method Lu Chuan adopted was to segment the bloody fingerprint into four relatively complete parts and then conduct identification and analysis on each part.
Simply put, this segmentation method transformed a fingerprint that couldn't be analyzed as a whole into four relatively independent ones for identification.
