The process of collecting bloodstains was relatively simple, and Lu Chuan completed it quickly.
Although the crime hadn't happened long ago, the bloodstains had already lost their vitality, making DNA extraction more difficult.
However, in the crime scene, there wasn't just one similar droplet-shaped bloodstain left behind.
Similar bloodstains were found beside the living room sofa, the edge of the coffee table, and the edge of the bedroom door.
"Start with blood type analysis, and compare it with both the victim and Wang Hui."
Liu Guodong also took these droplet-shaped bloodstains seriously.
DNA extraction is time-consuming and the success rate cannot be guaranteed, but blood type verification is much simpler.
Using blood type test paper, you can get results in less than five minutes.
"Master, look at these two bloodstains."
Starting from the entrance, Lu Chuan attempted to reconstruct the crime scene based on the bloodstain patterns.
