The Underlying Reasons 2 Chapter 71

People who are used to reading mystery novels may fantasize about the life of a criminal policeman, thinking that the criminal policeman solves cases just like in novels, and the truth of the case can be revealed as long as the famous detective makes some reasoning. However, reality is often not as exciting as novels. Many times, the investigation of a case requires investigators to conduct boring investigations for several days or even weeks. In the following days, the serious case team and the forensic team went back and forth in this "investigation---blood sampling---comparison". Because the investigation area is large, the two groups have prepared for a protracted war. However, what everyone did not expect was that the breakthrough came much faster than they expected. On July 16, they found matching blood samples in the fifth batch of test subjects! !

"According to the records, the person whose blood was drawn was named Nie Yunquan, male, 45 years old, a villager from Caiqi Town, Yunxi County." Jason handed the materials to Sean, "We compared his blood with the suspect's twice, and his Y-STR genotype completely matched the suspect, but the DNA was not compatible. In other words, the murderer is someone from the same paternal family as him, but not him."

"Next, we will find all the male members of his family, and then conduct further comparisons to gradually narrow down the scope." Ryan said, "Of course, you can also cross-check the male members of his family with the people involved in the case to see who can find the murderer first."

Sean nodded: "I think so too." He looked at Ryan and Jason, "Then let's do this. Let's do our best to identify all the members of this family, and then you two groups will continue to narrow down the scope along the DNA line. I will still start with the people involved in the case and the alibi. Let's move forward on both sides at the same time and try to find the murderer as soon as possible."

"good!"
