The body, which had been decomposing for two weeks, had its blood long decayed, making it impossible to determine DNA information through blood analysis.
Lu Chuan collected hair and nails.
As for fingerprints…
Collecting fingerprints from a highly decomposed body is an extremely challenging task; of course, Lu Chuan was working on it, but it took quite a long time.
Moreover, the subsequent fingerprint comparison was also difficult. Lu Chuan planned to do DNA identification analysis first and then try fingerprint identification if the comparison did not succeed.
Of course, these are just conventional identity identification methods; if they all fail, they can actually reconstruct the deceased's portrait based on the head.
A portrait artist is not a new technical profession in the criminal investigation industry.
